Where you place your modem in your home is important, but probably not for the reasons that you think.

You’re probably wondering if the location of your modem will impact the speed of your internet connection. That’s the biggest concern of most internet users.

Fear not, because I have some good news for you.

Where you keep your modem in your home won’t have any affect on your internet speed. With that said, the location of your modem is important for making sure it lasts as long as it should. If you don’t keep your modem in a proper location, you may find yourself replacing it sooner than you’d like.

In this post we’ll look at why the placement of your modem is important, as well as the best locations for your modem in your home.

How do your modem and router provide an internet connection?

Let’s first address the question that everyone is most worried about: Does your modem location affect your internet speed?

In order to understand if the location of your modem affects your internet speed, we need to have an understanding of how your internet devices get access to the internet. The two devices responsible for providing internet in your home are your modem and router.

What role does your modem play in your internet connection?

When it comes to the internet connection in your home, your modem basically has one job.

It’s responsible for connecting your house with the rest of the internet.

Your modem provides your home with access to the internet by establishing a connection to your internet service provider (ISP). Your ISP is the company that provides you with your internet plan (e.g. Xfinity, AT&T, Verizon, etc.).

By connecting with your ISP, your modem makes it possible for your devices to use the internet to receive email, browse websites, online shop, etc.

You can think of your modem like a key to the internet. Your modem opens the door for your devices to access the internet.

To put it simply, you need a modem if you want internet access. If you only had a router and you didn’t have a modem, your devices wouldn’t be able to reach the internet.

It’s as simple as that.

Due to the fact that your modem has such an important job, it doesn’t come with many extra features. It doesn’t assign your devices with IP addresses, provide a wireless internet signal for your devices, or coordinate the sending and receiving of data to the internet.

That’s where your router comes in.

What role does your router play in your internet connection?

If your modem connects your home to the internet, you might be wondering what your router does.

Pretty much everything else.

First and foremost, your router allows your devices to wirelessly connect to the internet. Your router uses its multiple antennas to broadcast your home’s internet connection through the air. The wireless devices in your home connect to your router through this signal, which allows them to access the internet.

Your router is able to broadcast this internet signal because it’s connected to your modem with an ethernet cable. Your modem passes the internet signal from your ISP to your router for broadcasting.

Here’s a diagram to help you visualize this:

If you have a modem and router combination device, your router won’t be connected to a modem with an ethernet cable. That’s because your modem and router will be housed in one device.

In addition to providing your devices with a wireless internet signal, your router also assigns IP addresses to your devices when they connect to your home network.

Once a device has been assigned an IP address, your router ensures that device only receives the information it requests. In other words, if you use your phone to enter a website address into your browser, your router will make sure that the requested website shows up on your phone and not on another device on your home network.

Does your modem location affect your internet speed?

Now that I’ve outlined the roles that your modem and router play in providing your home with an internet connection, we can answer if the location of your modem affects your internet speed.

As you’ll recall, your modem is connected to two things. It’s connected to your router with an ethernet cable, as well as to your Internet Service Provider.

The connection from your modem to your ISP is a wired connection as well. If you have cable internet (which most people do), your modem will be connected to your ISP through a coaxial cable.

This coaxial cable will connect to a cable jack on the wall and run outside of your home to your ISP. Here’s an example of what a cable jack looks like:

You may be asking, why is this important?

It’s important because of what these two connections have in common. They’re both wired.

The benefit of wired connections

When it comes to sending and receiving data, communication over wired connections is very fast. To take it a step further, sending data through a wire won’t usually have any impact on your internet speed.

In fact, the only time a wired connection will impact your internet speed in your home is if your modem and router are connected with an ethernet cable that’s longer than 328 feet (100 meters).

This basically means that as long as your modem and router are connected with an ethernet cable that is less than 328 feet long, it doesn’t matter where you put your modem in your home.

Remember, your modem doesn’t broadcast the WiFi signal to your devices. That’s your router’s job. All it’s responsible for is connecting your home to your ISP.

As long as your modem is connected to your router and ISP, it shouldn’t have any effect on your internet speed. It doesn’t matter where it’s located in your home.

Does your router’s placement affect your internet speed?

Unfortunately, the same can’t be said for your router.

As I mentioned earlier, your router wirelessly connects to your internet devices. As a result, if your devices are far away from your router, they’ll have a weaker internet signal.

A weaker internet signal will lead to slower internet speeds. This is why it’s important to place your router as close to your internet devices as possible.

Where you should place your router is another topic entirely. For now, I wanted to provide you with the basics to make it clear that your router placement can have a much bigger impact on your internet speed than the placement of your modem.

Does modem placement matter?

If the location of your modem doesn’t affect your internet speed, does it matter where you put it?

You might be surprised to hear that the answer is yes.

There are other reasons to care about where you place your modem. For example, if you’re not careful about your modem’s placement, it won’t last as long as it should.

Why modem placement is important

The location of your modem in your house is important for several reasons. The first (and most important) reason is that your modem can overheat if it’s not placed in the proper location.

The other reason why modem placement is important is for organizational purposes. You’ll most likely want your modem near the internet connection that goes to your internet service provider. Placing your modem near the internet jack in your home will make it much easier to set up your internet connection.

Lets’ take a closer look at each of these topics.

It can help prevent your modem from overheating

If you buy the right modem and take good care of it, it can last you up to ten years or more. With that said, if you don’t take care of your modem, you may have to replace it much sooner.

Nobody wants to deal with that.

So what exactly am I talking about here?

I’m talking about dust and heat. You need to avoid dust and heat as much as possible if you want your modem to last.

If your modem is in a location where it accumulates a lot of dust, it’ll run hotter than it should. When electronic devices get hot, they have a tendency to overheat. If your modem overheats, its electronic components inside the device can fail.

We all know what that means. If your modem’s internal components fail, you’ll need to replace your modem.

Your modem can also overheat if it’s placed too close to a heat source like the heaters in your home. You don’t want to place your router and modem on top of each other either. Doing so will cause both devices to run hotter than they should.

So where should a modem be placed to help prevent it from overheating?

The key here is to keep your modem standing upright and in a well ventilated area. Ideally, you’ll want to keep it on an elevated surface like a table or shelf. This will keep it away from dust on the ground and make sure it’s getting proper airflow to cool it.

Any elevated surface will do. For reference, here’s my modem on a chair in my living room.

If you live in a climate controlled house, you shouldn’t have any issues. Just make sure your modem is off the ground and you’ll be all set.

It makes it easier to set up your home internet

Another factor you should consider when deciding where to keep your modem is its distance from the connection to your ISP.

As I mentioned earlier, your modem needs to connect to both your router and the internet connection that comes from outside your house.

The farther your modem is from the internet connection, the more complicated it’ll be to set up your internet.

Why is that?

If your modem has to connect to the internet jack that comes from your ISP, the shorter the cable the better. The farther your modem is from this jack, the longer the cable connecting them has to be.

You don’t want to have a long cable snaking throughout your house to connect your modem to your ISP. Not only is it a tripping hazard, but it also makes your house look messy and unorganized.

Some houses have multiple jacks that connect your home to your ISP, which makes things a little easier. You can just connect your modem to the closest jack to minimize the length of the cable connecting the two.

The bottom line is, it’s much easier to keep your modem in a place that’s close to the internet jack that goes outside your house.

Especially since your modem placement won’t affect your internet speed, it’s worth finding a spot close to your internet jack.

Modem placement recommendations

By now you should have a pretty good idea where to locate your modem in your home.

Ideally, there’s a place in your home that allows you to:

• Keep your modem close to the internet jack that connects your home to your internet service provider
• Place your modem on an elevated surface near the internet jack so you can keep it off the ground
• Put your modem in a room that’s either climate controlled or gets steady, natural airflow

If you’re able to keep your modem in a space that meets the above criteria, you’re in good shape.

If you’re not able to meet the above criteria, the one factor that’s the least impactful is the distance from the internet jack. You’ll have a longer cable connecting your modem to your ISP, but it won’t affect how long your modem lasts.

Regardless of where you keep your modem, try to keep it in an open area that’s off the ground. These are the two factors that can result in your modem failing before it should, so they’re the most important.

How Long Do Modems Last? A Complete Guide

Can a Modem Overheat? What to Look For

Does Your Modem Affect Your Internet Speed?

Can I Take My Internet Modem to Another House?

Many sites will tell you that your modem should be replaced every three to five years.

Honestly, I don’t agree.

From my experience, modems should last much longer before being replaced.

So how long should modems last?

The truth is, it depends.

There are a lot of variables that go into how long a modem will last. One thing I will say with certainty: if you do your homework when selecting your modem and take good care of it, it can last you up to 10 years or longer before being replaced.

You shouldn’t need to replace your modem as long as:

• Your internet needs don’t drastically change
• You’re taking care of your modem to prevent it from overheating
• Your modem manufacturer is providing firmware updates for it
• You don’t need to change your internet provider

In this post, I’ll break down the reasons why you might need to replace your modem. I’ll also detail what you can do to ensure your modem lasts as long as possible.

When you will need to replace your modem

Before we get into what you can do to make sure your modem lasts a long time, let’s talk about the situations when you’ll need to replace your modem.

By identifying the reasons why you might need to replace your modem, we can determine what steps you can take to avoid these situations.

Your internet needs change

One of the most common reasons that people get a new modem is because their internet needs change. In other words, people need modems that can support faster internet plans.

Why would your internet needs change?

Most of the time, your internet needs will change if the number of people using the internet in your home changes. For example, imagine a new roommate moves in with you or you have a child that will be using the internet (or streaming kid’s TV shows).

This might also come into play if you start online gaming or livestreaming from your house. Your current internet plan may not be able to support this additional internet activity.

So what do you do?

You get a new internet plan that offers more bandwidth. If your current modem can’t support the bandwidth of this new internet plan, you’ll need to get a new modem.

This is a logical reason to replace your modem because if you’re not careful, your modem can limit your home’s internet speeds.

Later on, I’ll explain what you can do to make sure you don’t need to replace your modem if your internet needs change.

Your modem breaks or overheats

This one should be pretty self-explanatory. If your modem breaks, you’ll have to get a new one.

At this point, modems are pretty reliable devices. Your modem won’t usually stop working on a whim (unless it’s really old).

That’s not to say that modems aren’t made with defects here and there. Sometimes there’ll be nothing you can do and you just have to replace your modem because it malfunctions.

Your modem overheating is a different story.

If your modem overheats, it’s possible it may stop working entirely. You’ll have to replace it.

The good news is, you should be able to prevent this from happening. We’ll touch on this later as well.

Your modem manufacturer stops supporting our modem

It may sound strange, but you want this to be the reason you replace your modem. To put it simply, you want your modem to last so long that the modem’s manufacturer stops supporting it.

When I refer to your modem’s manufacturer supporting your modem, I’m talking about firmware updates.

Your modem’s firmware

The software that’s responsible for running your modem is called firmware. This firmware is encoded onto your modem and it can’t be changed unless a new version of firmware is installed. Firmware controls:

• How your modem handles its connection with your internet provider
• The startup process it follows when you reboot it
• What the modem settings page looks like when you access it
• All other aspects of how your modem functions

Any time bugs are found in the firmware of your modem, your modem’s manufacturer will issue firmware updates to correct them. These updates help to keep your modem firing on all cylinders.

In addition, updates will be released when security flaws are found in your modem’s firmware. This is of utmost importance, as you don’t want to be using a modem that’s vulnerable to hackers.

Manufacturer support

Generally, manufacturers will only stop releasing updates for a modem if it’s really old.

When a modem’s manufacturer stops supporting a modem, it means they won’t fix any more issues that are found in that modem’s code.

This is like an auto shop refusing to fix your car if it’s a certain age.

If any security flaws are found in your modem, you’ll be left to fend for yourself. As a result, you need to avoid this situation entirely. If your modem’s manufacturer stops updating the firmware for your modem, you should get a new one.

If you don’t, your modem’s performance can suffer. More importantly, it may be subject to cyber attacks because its security holes will remain unpatched.

It’s important to mention here that manufacturers usually support their modems for a long time. If you have a newer modem, you have nothing to worry about.

For example, I have a Netgear CM600 modem. On the cover of my modem’s user manual, it displays the year that Netgear started selling this model.

As you can see, Netgear first released this modem in 2015. As of this writing, they’ve been providing updates for it for the last 7 years with no signs of stopping.

If you take care of your modem as described in the next section, you should expect your modem to last as long as the manufacturer will keep supporting it.

Your internet provider does not support your modem

This one goes hand-in-hand with ensuring your modem gets updated.

If your modem isn’t compatible with your internet service provider (ISP), you should get a modem that is.

Your modem will only receive updates if your modem’s model is supported by your internet provider. Not to mention, if your modem isn’t supported by your ISP, you won’t even get an internet connection. If you’re unsure if your modem is supported by your internet provider, it’s pretty easy to check.

A modem that doesn’t receive updates is a huge cybersecurity risk. Any security flaws in your modem will go unfixed, leaving doors to your home network wide open.

On top of that, a modem that doesn’t receive updates won’t function as well as it should. There’s no way your modem will last a long time if it isn’t running properly.

The same applies if you move or change internet providers.

If your ISP is going to change, you need to make sure your modem is compatible with the new ISP. If not, your modem won’t receive the critical updates it needs.

Take a few minutes to find out if your current modem will be supported by your new ISP. If it won’t, make sure you get a supported modem by the time you start your new internet plan.

How to ensure your modem will last a long time

So you want you modem to last a long time.

Don’t we all.

You increase your chances of your modem lasting a long time if you do your homework when deciding which one to get. If you take care of your modem once you have it, that’ll go a long way as well.

Let’s break down each step you can take to prolong the life of your modem.

Future-proof your modem

The modem you pick for your home internet can have a large impact on your internet experience.

Sure, picking the right modem can ensure you get fast internet, but there’s more to it than that.

If you pick a modem that meets your current and future internet needs, you increase the chances of your modem lasting a long time.

This is also known as future-proofing.

If you buy a modem that just fits your current needs, you may have to get a new one if your internet needs change. A good strategy here is to think about how your internet needs might change.

Here are some important questions to ask yourself:

• Will the number of internet users in my household change?
• Do I anticipate having greater bandwidth needs in the future (e.g. streaming, gaming, etc.)?
• What will my upload requirements be in the coming years?
• Will I be working from home more often in the future?
• Do I plan on moving far away at some point?

Thinking about these questions in advance will help in your decision-making process when picking out a modem. If you get a modem that will support your internet needs for a long time, you increase the probability that you will have it for a long time.

Also keep in mind that your modem needs to be compatible with your internet provider in order for it to work. This should be the first thing to check when looking at a modem. It doesn’t matter how fast it is if it won’t work with your internet provider.

When it comes to your modem, the upfront planning you do can have a large impact on how long it’ll last.

Ensure good modem placement

Let’s say you’ve done your homework and picked out a modem that’ll fit your internet needs for years to come.

Now what? What else can you do to make sure your modem lasts a long time?

Another factor in extending the life of your modem is all about placement. You might not think it’s a big deal, but where you put your modem is very important.

So what does this mean, exactly?

You’ll want to make sure your modem is in an open area of your house. It should also be free from obstructions. In other words, don’t stack anything on top of your modem or put it near any other heat-generating items (like heaters).

Not only that, you’ll want to make sure it’s off the floor if possible.

Here’s how my modem is set up.

As you can see, it’s off the ground and there’s nothing too close to it.

The importance of airflow

Taking these steps will ensure that your modem gets proper airflow.

Why is this important?

Your modem is an electronic device that is powered on almost 100% of the time. As a result, it will generate a lot of heat. In order to remove the hot air and cool your modem down, it needs air circulating through it.

If it doesn’t get proper airflow, your modem will get hot. If it gets too hot, there’s a chance it could overheat.

In addition, make sure your modem is out of direct sunlight if you can. Sunlight will only make your modem hotter.

If your modem is in a temperature controlled room this is less of an issue. Regardless, this is something you should be aware of.

If you modem overheats, you’ll get slow internet. Even worse, your modem might stop working altogether.

So do your modem a favor. Put it on a table or shelf in an open room where it’ll get plenty of airflow. I promise it’ll pay off in the long run.

Modem maintenance

If you want your modem to last a long time, you need to be maintaining it on a regular basis.

Before you get overwhelmed, let me say that I’m not talking about anything crazy here.

In fact, modem maintenance can be done in a few minutes. Even better news is that if your modem is placed in a good location of your house (as we’ve discussed), you may not need to do any maintenance on it at all.

Ok let’s get on with it. What exactly do I mean by modem maintenance?

The problem with dust

To put it simply, I’m talking about keeping your modem free from dust.

Why is dust such a big deal?

This is directly related to making sure your modem is placed in an open location with proper airflow. If your modem is in a location with bad airflow or it’s on the floor, dust may collect on the inside of the device.

Dust can get inside your modem through the vents that are designed to keep it cool. For reference, here’s a picture of the vents on my modem:

All those little holes on the modem serve to promote airflow through the device. If you look closely, you can see through the other side of my modem in some spots.

If those vents get clogged with dust, your modem won’t cool down like it should. As you might have guessed, this can lead to your modem overheating.

What’s promising about this is that there’s an easy fix. This is the maintenance I’m talking about.

How to remove dust from your modem

All you need to do is monitor the buildup of dust on your modem. Every few months or so, free your modem of any dust that has built up inside it.

I know what you’re thinking. How do I do that?

It’s actually really easy. All you need is a can of compressed air like this one.

Just use some short bursts of compressed air to spray air through the vents of your modem. This will help free up and remove any of the larger dust particles.

You may not physically see any dust particles fly out of your modem, but it’s a good practice just to make sure your modem vents aren’t restricted.

Do this every few months or if you can see dust buildup on your modem. It’s a two minute task that will help ensure your modem lasts as long as it should.

It’s well worth the effort.

Ensure your modem’s firmware is updated

There’s one last thing you’ll need to do to ensure your modem will last a long time. You need to make sure your modem gets updated when new versions of software come out for it.

Updating your modem’s firmware will ensure it operates at maximum efficiency. In addition, firmware updates will address any security weaknesses that have been discovered about your modem.

It’s obvious why you would want to keep your modem’s firmware updated. Not only will an updated modem keep your internet connection as fast as possible, but it’ll also ensure it can’t be easily attacked by hackers.

So how do you update your modem? It’s kind of a trick question.

Updating your modem

Keeping your modem updated should be really easy for you. In fact, you shouldn’t have to do anything at all.

That’s because your modem’s manufacturer is responsible for updating it for you.

When your modem’s manufacturer has an update for your modem, they’ll submit the update to your internet service provider. Your ISP will then push the modem update over your internet connection to your modem.

All of this should happen automatically. You won’t even know when your modem is updated.

In this sense, making sure your modem is updated is probably the easiest thing you have to do to ensure it lasts a long time.

How long will a rented modem last?

What if you rent your modem from your internet provider? Will that change anything when it comes to how long it lasts?

If you rent your modem from your ISP, the game changes a little bit. That’s because you don’t have to worry as much about making your modem last a long time.

Confused about this? Hear me out.

When you rent your modem, your ISP will give you a new modem if your rented modem fails. They’ll also provide you with an upgraded modem if the one you’re renting becomes obsolete. This is all included in the monthly fee that you pay for renting your modem.

With that said, you should still take care of your rented modem by following the steps I outlined in this article. If your rented modem is frequently breaking, your internet provider may charge you for a replacement.

If you take good care of your rented modem, it should last just as long as a personal modem. With that said, you probably won’t need it to. You can count on your ISP replacing your rented modem more often than every 10 years.

Wrap up

Here’s the bottom line: if you take good care of your modem, it can last way longer than three to five years. Now you have everything you need to make that happen.

I’d love to hear about your personal experiences with your modems and how long they’ve lasted. Drop a comment below if you’d like to share, or if you have any questions about the above information.

Does Your Modem Affect Your Internet Speed?

How to Update Modem Firmware: A Complete Guide

Can I Take My Internet Modem to Another House?

Why Do Modems Need to Be Rebooted?

I’ll start by giving you a scenario.

Let’s say a couple is moving to a new home in a different area. As a result, they have a new provider for their internet connection.

On moving day, they pack up everything they own and move it to their new home.

At the new house, they quickly unpack and realize one of the first things they want to do is set up is their internet. They thought ahead and paid for a plan with their new internet service provider (ISP), so everything should be in place.

They plug in their internet equipment and follow the steps to set up their internet connection. It’s at this point that it all comes grinding to a halt.

How can this be?

Their modem worked in their old place. Why wouldn’t it work now?

Isn’t a modem compatible with all ISPs?

Modems are not compatible with all Internet Service Providers. A modem will not be able to establish an internet connection if it is connected to an ISP it is not compatible with.

If reading this information makes you nervous, don’t be alarmed.

In this post I’ll break down why your modem may not be supported by your ISP. I’ll also explain how you can verify what ISPs your modem supports.

Can I Use My Modem With Any Internet Provider?

You may be surprised to hear that your modem isn’t like your other electronic devices. You can’t just plug it in and expect it to work.

In fact, your modem isn’t even like your router. Although your router will work no matter who your internet service provider is, your modem may not.

Your modem will only work with a given set of ISPs. As a result, you need to be really careful when picking out a modem.

As you read in our example above, this often comes into play if you’re moving and have to switch your ISP. Your new ISP may not support the current make and model of modem you have.

So what do you do?

Thankfully, there are a few easy ways to make sure your modem is compatible with your ISP. We’ll get into those later.

Why Wouldn’t My Modem Work With My Internet Provider?

If your modem doesn’t work with a given ISP, there are two main reasons why that could be the case. Let’s take a close look at both of them so you know what you need to be aware of.

Your ISP Provides a Different Type of Internet Connection

The first reason why your modem won’t work with your ISP is if your ISP provides a different type of internet connection.

There are multiple ways to connect to the internet. Some of the most common ways include:

• Cable
• Fiber
• DSL
• Satellite

These different ways of connecting to the internet make the internet available to most people. At the same time, it can complicate things.

For example, you need to make sure your modem is compatible with the type of internet connection you have.

If you have a cable internet plan, you need to make sure your modem is built for that. You won’t be able to connect your modem to the internet if you have a fiber internet connection but your modem is built for cable internet.

Your Modem Is Not Supported by Your ISP

The other potential reason your modem won’t work with your internet provider is if they don’t support your modem’s make and model.

I was actually surprised when I first learned this.

The bottom line is, internet service provider’s can’t support every modem. They need to be selective about which ones they support.

Why’s this?

This is because your ISP is responsible for updating your modem’s firmware for you.

Before they’re able to push updates to your modem, your ISP needs to test them to make sure the update doesn’t mess anything up with your internet connection.

They need to do this every time a firmware update is released for a given modem. Depending upon the modem, firmware updates may be released multiple times per year.

For your ISP, they can’t afford to perform all these tests for every modem on the market. It would be too expensive for them.

So what do they do?

They support the modem models that are the most popular.

That’s why if you have a modem that’s not a common make or model, it may not be supported by your ISP.

The same goes for older modems. If your modem is old, the chances are less likely that your internet provider will support it.

In fact, if a modem is old enough, the modem manufacturer will stop providing updates for it. When your modem’s manufacturer isn’t supporting your modem anymore, you should get a new one anyway.

That’s a topic for another time.

How to Tell What Type of Modem You Have

Let’s revisit the type of internet connection your modem supports.

What if you’re not sure what type of internet your modem is made for? How can you figure it out?

The good news is, it shouldn’t be hard to determine.

Let me start by saying most modems are made for cable internet. In 2021, over 194 million people in the United States had cable internet connections.

In other words, chances are you have a cable modem and cable internet connection.

Don’t take my word for it though. You should check for yourself to make sure you don’t make the wrong decision about your internet plan.

For one, fiber internet has become increasingly more popular. It’s also possible you have a DSL modem, even thought DSL is an older internet technology.

With all these options, it’s better to find out for sure what your modem is made for.

There are two easy ways to figure it out.

Look at the Ports on the Modem

The easiest way to tell what type of internet connection your modem has is to simply look at your modem.

If you look at the back of your modem, it’ll probably give you the answer you’re looking for.

The first thing you have to do is find the wire that provides your modem with an internet connection. Feel free to unplug the cable to get a closer look at a time when you’re not using your internet connection.

If that cable is a coaxial cable that looks like the one that plugs into your cable box, you have a cable modem.

If it’s a phone cable, you have a DSL modem.

Lastly, if it’s a fiber optic cable, you have a modem built for a fiber internet connection.

Still aren’t sure?

If you can’t tell just from looking at the cable, look at the port it connects to on your modem. It may be labeled with the type of internet connection it’s made for.

For example, here’s the back of my CM600 modem.

See?

It says right on the back of my modem that it’s for a cable internet connection.

It doesn’t get much easier than that.

Unless of course you know the make and model of your modem. If you know what model your modem is, you can find out what type of internet connection it’s for without getting off the couch.

Look at the Modem’s Product Page

The other way to find the type of connection your modem is for is to look it up online.

The product page for your modem will tell you all you need to know.

Before we go any further, let’s make sure you know what your modem’s make and model is. To do this, just look at the sticker on your modem.

Check the bottom of your modem. That’s where the sticker is usually located.

The sticker will provide you with your modem’s model, as well as its manufacturer.

Here’s the bottom of my modem:

The manufacturer of my modem is Netgear, and the model is CM600.

Surprisingly, you can even see that it identifies my device as a cable modem right on the sticker.

I don’t need to go any further. I know my modem is built for cable internet. For the sake of this exercise I’ll continue the process in case the sticker on your particular modem doesn’t provide what type of internet it’s for.

Now that I know I have a Netgear CM600 modem, all I have to do is search for its product page online.

This lead me to Amazon’s product page for my modem. The product page gave me exactly what I was looking for:

The product page clearly identifies that my CM600 modem is for cable internet plans.

At this point my search is over. I’ve confirmed that my modem is made for an ISP that provides cable internet.

How to Look up the Internet Providers That a Modem Supports

What if you have a modem and you want to find out what ISPs it works with?

There are two ways to go about answering this question as well. One option is to go back to the product page for your modem that we were looking at earlier. Another option is to go directly to the source, which is an ISP’s website.

Look at the Internet Provider’s Support Page

Let’s say you want to find out if a specific ISP supports your modem. There’s no better place to look than the provider’s website.

Although you can also look at your modem’s product page, going to the ISP’s website is more reliable. Depending upon the product page you’re looking at, sometimes you might not get the most accurate information.

Anyway, back to the task at hand.

As I mentioned earlier, your internet provider is responsible for updating your modem for you.

As a result, ISPs will usually publish a list of the modems they support on their website. That’s because they don’t want their customers to have to guess what modems will work with their internet plan.

In the end, internet providers want you business. They want you to get a modem that’s supported by their internet plans so you don’t leave them for their competitor.

So where exactly do you need to look?

The best place to look is the support page. We’ll use my ISP as an example.

Accessing the ISP’s Support Page

I have a cable internet plan with Xfinity by Comcast.

I start by firing up my internet browser and navigating to Xfinity’s website. In a few clicks I find myself on the Internet Support page.

On the Internet Support page, there are a few headers to choose from. The one that stood out to me was “Using Your Own Equipment”.

I want to see if my personal modem is supported by Xfinity, so this header made sense to me.

When this section expanded, I saw the article I was looking for. I figured “Approved Equipment for Xfinity Internet and Xfinity Voice” was a good place to start.

After accessing this article I found a page that required me to put in my address and the speed of my internet plan. Once I entered this info, I was given a list of modems that Xfinity supports for my internet plan and geographic location.

Low an behold, I found my Netgear CM600 on the list.

This confirmed that Xfinity supports my modem. Of course I already knew this because I have a working internet connection, but these are the steps you’d need to follow if you want to check if an ISP supports your modem.

I did a few searches of common ISPs and it looks like all of the largest providers have lists of the modems they support.

Look at the Modem’s Product Page

The other option for looking at what internet providers are compatible with your modem is to go back to your modem’s product page.

To do this, follow the same steps that I detailed above.

I’ll use my modem as an example again.

Looking at information about my modem, it states the major ISPs it’s compatible with.

As you can see, my Netgear CM600 is compatible with Xfinity, Cox, and Spectrum.

Does this mean those are the only ISPs it’s compatible with?

Not necessarily.

Those are just the major providers that support my modem. If there’s a smaller, less well-known internet provider in your area, go to their support page or call them to see if they support your modem.

It’s possible that your modem is compatible with a smaller ISP. It just doesn’t make sense for a seller to list all the internet providers that are compatible with the modem on the product page. The list could be endless.

How to Ensure Your Modem Is Compatible With Your ISP

Does the information above overwhelm you? Would you rather not have to worry about your modem being compatible with your internet provider?

If this is the case, there’s an easy way out for you.

That’s to rent your modem directly from your internet provider.

If you rent a modem from your ISP, you know it’ll be compatible with their internet connection. It wouldn’t be very smart of them to rent you a modem that doesn’t work with their internet.

Although this is the easiest method for finding a compatible modem, it comes with a few drawbacks.

The first is that renting a modem will cost you more money in the long run than buying your own modem. When you rent a modem you’ll be charged a monthly free from your ISP.

In some cases, it can cost as much as $15 per month (or more) to rent a modem. Compare that to buying a modem where a good one will run you $100 or less. It’s easy to see that a year of renting a modem can be more expensive than buying your own.

On top of that, when you rent a modem you don’t get to choose what model it is. This might not give you the best internet performance because your modem won’t be specific to your individual internet plan.

Buying your own modem allows you to find one that fits your specific needs.

That’s not to say that renting a modem won’t give you a fast internet connection. That’s still possible if you rent. You just might not squeeze every bit of speed from your internet plan.

With all that said, if you’re willing to sacrifice a little bit of performance and pay a little bit more, renting a modem can be a convenient option. Especially if you get stressed out about trying to find a modem that’s compatible with your ISP.

Wrap Up

Many people have made the mistake of getting a modem that isn’t compatible with their internet service provider. In reading this post you’ve ensured you won’t be one of them.

If you have any questions about this information or you’d like to share you personal story, I’d love to hear from you in the comments section below.

How to Update Modem Firmware: A Complete Guide

Can You Use a Modem Without a Router?

Can I Take My Internet Modem to Another House?

How Do I Reset My Modem Password?

Your modem needs to update its firmware whenever the manufacturer issues a new version of it. New versions of firmware will be released when your modem manufacturer fixes a bug or addresses a security concern in your modem’s software.

By updating your modem’s firmware, you’re improving both the security and performance of your modem.

So how do you update your modem’s firmware?

Users are not responsible for updating the firmware of their modem. Internet service providers (ISPs) update modems with new firmware when updates are released by the modem manufacturer. In general, these updates happen automatically without any needed action from the owner of the modem.

In this post I’ll break down everything you need to know about updating your modem. We’ll discuss:

• How your modem firmware is updated
• Where you can find your modem’s current firmware version
• How to determine what firmware version your modem should have

Let’s get going.

What is Modem Firmware?

Before we go over the process of updating your firmware, let’s start from square one.

What is your modem’s firmware, exactly?

Your modem’s firmware is the software that determines how your modem functions.

This includes:

• How it starts up and shuts down
• How it connects to your ISP to provide you with an internet connection
• What the settings page looks like when you log in to your modem’s settings

If you haven’t noticed by now, it’s a very important part of your modem. In fact, your modem won’t work without it.

When you receive a modem, the firmware will come preloaded on it. That’s because the manufacturer builds your modem with the firmware embedded on a computer chip in the device.

The only way your modem’s firmware can be changed is by updating the firmware or installing brand new firmware on the device. As a user, you can’t make any changes to how your modem’s firmware functions.

Why Should I Update My Modem Firmware?

Making sure your modem’s software is updated is very important.

Any time a software bug or security flaw is found in your modem’s code, the manufacturer will update the code for your modem and issue an update.

If your modem’s firmware isn’t updated, it won’t receive any performance or security updates that the modem manufacturer develops.

This includes new features as well. If your modem manufacturer develops a new feature for your modem, you won’t be able to use it unless you have the latest software.

Chances are, you paid good money for your modem. Even if you’re renting it and paying monthly. You want to make sure you’re getting the best performance, features, and security to go with it.

Especially today with everyone emailing, banking, and shopping online, you want to make sure your internet connection is as secure as possible.

How to Update Your Modem Firmware

When it comes to updating your modem, there’s good news and bad news.

The good news is that the process for updating your modem doesn’t require as much effort as updating your router does. In fact, updating your modem requires no action on your part at all.

That’s right. You read that correctly.

You aren’t responsible for updating your modem. Your ISP is.

Ok so if that’s the good news, what’s the bad news?

Before we get into that, let’s break down how the modem update process happens.

How Does Your ISP Update Your Modem Firmware?

Any time your modem manufacturer issues an update to your modem’s firmware, they send it to your ISP.

From there, it’s your ISP’s job to make sure your modem gets updated.

Before the update is pushed to your modem over your internet connection, there’s more to be done.

When an ISP gets a firmware update for a specific modem, they have to check and test it. First and foremost, your ISP needs to make sure that the internet connection between the ISP and the modem owner (you) still works properly after the update.

Once the modem update has been tested and everything works properly, your ISP will issue the firmware update.

This firmware update will only affect the modems connected to the ISP of that specific make and model. In other words, your modem will only be updated if your manufacturer issued an update for your specific model. All other modems connected to the ISP won’t be updated.

When your modem receives the update, it’ll automatically install it.

This’ll all be invisible to you. The only way to know if your modem was updated is to check the firmware version on the device, which we’ll get to later.

Ok. So earlier I mentioned there was bad news when it comes to updating your modem.

Now that I’ve described how your modem should be upgraded, let’s take a look at the downside.

The Bad News About Modem Firmware Updates

What’s bad about your ISP updating your modem for you? It seems like a pretty easy process.

The problem with your ISP being in charge of updating your modem is that your modem doesn’t always get updated like it should.

This can be especially true when your internet plan isn’t with a large provider. For example, I’m talking about the major players like AT&T, Comcast/Xfinity, Verizon, or Cox Communications.

Let’s looks at it from an ISPs perspective.

They have thousands of customers, and their customers all have different modems.

Some modems are brand new.

While others are older.

Some are made by large manufacturers.

While others are made from smaller, less well known manufacturers.

The bottom line is that there could be thousands of different modems connected to a given ISP. As a result, it makes it really hard to manage all of these modem updates.

Let’s say you have an older modem that’s not very popular.

Is your ISP going to spend a lot of effort testing and checking modem updates for that modem if only a small number of their customers have that same model?

I don’t think so.

Another thing to keep in mind is that checking and testing modem updates costs your ISP money.

Are they going to spend money to have updates tested for a modem that only a small number of their customers have?

Especially if you have an internet plan with a smaller ISP. They may not have a budget for testing that other, larger ISPs have.

Hopefully you can see the bigger picture here.

The bottom line is that you don’t have the same amount of control over your modem updates because your ISP is responsible for updating it.

As a result, all ISPs don’t update modems like they should.

How to Tell if Your Modem Firmware Has Been Updated

If your ISP isn’t going to update you modem when they should, you need to know about it.

So how do you go about confirming that you have the most updated version of firmware on your modem?

The first thing to do is check what firmware version your modem currently has.

How to Check Your Modem’s Current Firmware Version

In order to check what version of firmware is currently installed on your router, you’ll need to access your modem’s settings.

In order to get to your modem’s settings, you’ll need to know your modem’s IP address.

Determine Your Modem’s Ip Address

Don’t worry if you’re not sure what your modem’s IP address is. You can usually find your modem’s IP address listed on a sticker on the actual device.

For example, I have a Netgear CM600 modem. On the bottom of my modem there’s a sticker that lists its IP address.

As you can see, my IP address is 192.168.100.1. Most modems should have a similar IP address.

If you don’t know your IP address and your modem doesn’t have a sticker on it, you should try looking online. Modems are shipped with default IP addresses, and there are many resources online that list what those default addresses are.

For example, this site details the common IP addresses for Netgear modem’s like mine. Just do a Google search for the make and model of your modem and you should be able to find its default IP address.

Log in to Your Modem’s Settings

Once you’ve determined your modem’s IP address, type it into your internet browser’s search bar.

This’ll bring you to your modem’s login page.

Log in to your modem with the username and password you created for it.

If you haven’t created a username and password, you can log in with the default values that come with the modem.

How do you know what the default values are?

Luckily, this information is listed on your modem as well. Just take a look at the same sticker you looked at to find your modem’s IP address.

If I hadn’t changed my default password, I’d be able to log in to my modem using “password” as my password.

If you don’t have these default values listed on your modem, you can most likely find them online. Similar to your modem’s default IP address, you should be able to find the default username and password for your make and model as well.

As a security note, if you haven’t changed the default password for your modem to a custom password, you need to.

As I mentioned, the default password for your modem can be found online, which means anyone with access to your network would be able to get to your modem’s settings.

Changing the default password of your modem will help keep hackers and bad actors from being able to mess with your modem’s settings. Just changing the password away from the default goes a long way towards making your modem more secure.

This is very important. Take the few minutes to change your modem’s password if you haven’t done so already.

Check the Firmware Version Installed on Your Modem

Ok, now you’ve logged in to your modem.

The next step is to see what version of firmware is installed on your device.

Thankfully, this is easy to find.

Right when I log in to my modem, the firmware version is listed right on the home page.

As you can see, the firmware version installed on my modem is V1.01.22.

If you have a different make and model of modem, your firmware version may not be listed on the Home page. As a result, I’ll show you another way of accessing this information in your modem’s settings.

Even if your modem is a different make and model, the steps to find out the firmware version of your device should be similar.

In my case, I can find my firmware version simply by clicking the Advanced tab.

Once on the Advanced tab, my modem’s firmware version is clearly listed.

Now you know what version of firmware is installed on your modem.

Find the Latest Version of Firmware for Your Modem

Ok so you know the firmware version of your modem.

The question is: is this the most recent version of firmware that your modem’s manufacturer has released?

There’s only one way to find out.

We need to go to the source to see what the latest firmware version for your modem is.

In this case the source is your modem manufacturer’s website. That should give us the information we’re looking for.

I’ll use my modem as an example. As a reminder, my modem is a Netgear CM600 modem.

My modem’s manufacturer is Netgear, so I did an internet search for Netgear’s website.

I accessed the Support section of Netgear’s website and was able to access the support page for my CM600 modem. Within this page, there was a header for firmware and software downloads.

Here’s what information was listed in this section.

This section says that firmware upgrades are provided by the ISP. We’re well aware of this at this point.

I wanted more information, so I clicked the provided “Knowledge Base” link.

The “Knowledge Base” provided a list of the latest firmware for all of Netgear’s modems. This was exactly what I was looking for.

Here’s what it showed for my CM600 modem.

As you can see, depending upon your ISP you may have a different version of firmware.

My internet plan is with Comcast, so it looks like my modem firmware should be version V1.01.22.

What a relief.

As we determined in the previous steps, I saw that my modem has firmware V1.01.22 installed. This means that my ISP is updating my modem like they should.

As a result, there’s no further action at this point. I just need to check back in a few months to see if a newer version of firmware has been released.

What to Do if Your Modem’s Firmware Is Outdated

In my case, my modem’s firmware matches the latest version released by the manufacturer.

What if this wasn’t the case? What can you do?

There are a few things you can do if your modem firmware doesn’t match the latest version.

We’ll take a look at each one so you have a good idea of what your options are.

Reboot Your Modem to See if It Initiates a Modem Firmware Update

If your modem says it has an old firmware version, the first thing to try is to reboot your modem.

When you restart your modem, it runs through multiple checks when it powers up.

One of those checks is to see if the latest firmware version is running on the modem.

If the modem isn’t running the latest version of firmware, it’ll get the updated firmware from your ISP and install it.

Essentially what you’re doing when you reboot your modem is forcing your modem to double check its firmware. If it’s out of date, it should update automatically as long as the ISP has issued the firmware update.

Once your modem has powered back up, check the firmware version again by following the procedure I previously outlined.

If the firmware is still outdated, try contacting your ISP.

Contact Your ISP to Update Your Modem’s Firmware

When it comes to your ISP, sometimes the squeaky wheel gets the grease.

If your modem’s firmware is outdated and rebooting your modem didn’t update it, give your ISP a call.

On some occasions it may take them a while to issue a firmware update after it’s released. If you call your ISP you can get a status of the firmware update. They should be able to tell you if they’re working on the update or not.

If enough customers call looking for a modem update, it might motivate them to get the the update released sooner.

On the other hand, they may tell you that they won’t be updating your modem’s firmware. If that’s the case, you can either look into getting a new ISP or buy a new modem.

Find a New ISP or Buy a New Modem

Let’s say you’ve tried rebooting your modem and calling your ISP.

Rebooting your modem didn’t work, and your ISP said they won’t by updating your modem.

What do you do now?

I would advise taking one of two actions. You can:

• Try to find a new ISP
• Buy (or rent) a new modem

It’s not safe for you to have a modem that isn’t updated, because it can leave you open to some serious security concerns. You need to take action.

Find a New ISP

If your current ISP won’t update your modem, maybe there’s another one that will.

Depending upon where you live, you might have a few different ISPs to choose from. If your ISP says they won’t update your modem, it might be worth calling their competitor to see if they’ll update your modem’s firmware.

For some people this won’t be an option, as there’s only one major internet provider in the area. This is the case for me. There’s only one ISP that provides coverage to my area, so my hands are tied on this front.

With that said, this isn’t the case for everyone. It might be worth taking a few minutes to see if there’s another ISP that can both provide you with internet and update your modem.

Buy (Or Rent) A New Modem

If your ISP won’t update your modem, it’s most likely that:

• The ISP you’re using isn’t a major provider
• Your modem is old or an uncommon make and model

If you don’t want to change your ISP (or there’s no ISP in your area) and you want your modem to receive updates, you don’t have much of a choice. You’ll have to change your modem.

One option is to rent a modem from your ISP. Renting a modem will just about guarantee that it’ll receive firmware updates. That’s because ISPs won’t rent out modems that they don’t update.

This comes with some tradeoffs though. Rented modems from the ISP are usually modem and router combination devices, and they don’t usually offer as many features as standalone modems and routers do.

On top of that, renting a modem can be expensive because you’re paying for it every month.

If you buy a new modem that’s a popular make and model, it’ll most likely receive updates from the ISP because a lot of their customers will have the same model that you do. On top of that, buying your own modem will be cheaper than renting a modem in the long run.

The bottom line here is that you want your modem to get firmware updates when they become available. Whether you find a new ISP or change out your modem, just make sure that your modem will get updated.

Wrap Up

I can’t say it enough. Your modem needs to be receiving firmware updates.

Although there may be less to do on your end when it comes to updating your modem, that doesn’t mean you should turn a blind eye.

You still need to check to make sure your modem is being updated. The risk is too great from a security standpoint not to. On top of that, you don’t want your internet performance suffering because your ISP won’t update your modem.

If you have any questions or you would like to share your personal experiences with your modem updates, please feel free to drop a comment below.

Does Your Modem Affect Your Internet Speed?

Does a Modem Have an IP Address?

Let me set the scene.

You’re getting ready to set up your home internet. You’re researching the different types of equipment you need for a blazing internet experience.

At this point you come to a roadblock.

“What’s the difference between a modem and router?”, you ask.

“Do I need both of them to access the internet? Or will a modem give me all I need?”

Before we go any further, I want you to understand that these types of questions pop up all the time. Especially when people are setting up their home internet for the first time.

The good news is, you’ve come to the right place for answers to all of your questions.

So let’s talk about your modem.

A modem should not be used on a home network without a router. Doing so would present significant cybersecurity risk to the network. Using a modem with a router allows multiple devices on a network to share an internet connection, and provides additional security to the network as well.

In this post I’ll explain why you shouldn’t use a modem without a router, the benefits that a router provides to your home internet, and what your home network should look like.

Let’s get started.

Why You Shouldn’t Use a Modem Without a Router

There are two main reasons why you shouldn’t use a modem without a router in your home network.

Modems and Routers Do Different Things in a Home Network

To put it simply, modems and routers are designed to do different things.

With that said, they both have important jobs when it comes to your internet connection. That’s why you need both of them for your internet to work properly.

By explaining what the jobs of your modem and router are, you’ll see why one shouldn’t be used without the other.

A Modem’s Responsibilities in a Home Network

The job of a modem is to provide your home with a connection to the internet.

Without a modem, you wouldn’t be able to access the internet in the first place. This is why you can’t use a router without a modem if you want to access the internet.

Once you pay for an internet plan from your internet service provider (ISP), you can use your modem to establish a connection with your ISP.

Your modem basically serves as a connection point between your home network and the internet. Think of it as a highway that your devices use to send (and receive) data to the internet.

One important thing to note here is that your modem doesn’t send any of the data from your devices to the internet. That’s the router’s job.

A Router’s Responsibilities in a Home Network

Your router’s job is to use the internet connection that your modem establishes to communicate with the internet.

It’s responsible for sending all the requests from your devices to the internet. When you want to access a website from your computer, the website request is sent from your computer to your router.

Your router then passes this request over the connection established by your modem to the internet.

The requested website is then returned from the internet to your router. Your router then forwards the requested website to the device that requested it.

For a visual, here’s a diagram showing how an internet request travels from your home network to the internet and back.

Without a modem to pass internet requests over, a router would be useless when it comes to internet connections.

Hopefully you can see why your modem and router are important, and why both devices are needed for an internet connection. Using a router has additional benefits as well.

Modem’s Don’t Provide Any Security to Devices on the Network

The other main reason why you shouldn’t use a modem without a router is because it isn’t safe to do so.

If you were to plug your computer directly into your modem without a router in between them, your computer would be exposed to the internet with very little protection.

You’d be a ripe target for all the hackers and malicious actors on the internet. This is because there’s nothing between your device and the internet that can filter out all the bad requests and hacking attempts targeted at your device.

Thankfully, when you include a router in your home network, your devices are much safer.

Not many people are aware of this, but your routers actually have security features built into them. They’re invisible to the user because they work in the background automatically.

Let’s take a quick look at the main security feature provided by routers.

Routers Provide a Network Address Translation Firewall

Routers protect the internet devices on your network with what’s called a Network Address Translation (NAT) firewall.

A NAT firewall is a built-in feature that comes with your router and works automatically. You don’t need to change any settings for it to work.

Without getting too technical here, the network address translation firewall works because of the fact that routers have two IP addresses: one for your internal home network and one for the external internet.

For any hackers or bad actors that try to send bad requests to your devices, they can only see the external public IP address of your router. They can’t see the internal IP addresses of the devices on your home network.

As a result, your router knows only to accept data that was requested by the internal IP addresses of the devices on your network. If it receives any data from the internet that wasn’t requested by one of your devices, your router knows to get rid of it.

In this sense, the NAT firewall serves as a filter for your devices. It ensures that your devices only receive the information they requested.

This is a level of protection that’s not provided if you plug a computer directly into a modem. Your device will receive all the bad requests that are sent to it because there’s no NAT firewall in place to filter them out.

The Benefits of Having a Router in Your Home Network

Ok so your router provides security to your devices and allows for them to communicate with the internet.

That sounds like a convincing argument why you should have a router in your home network.

In case you need more convincing, there are additional benefits that a router provides to your home network that you should be aware of as well.

Let’s take a look at these additional benefits.

A Router Allows for Multiple Internet Connections at the Same Time

One important feature of routers is that they allow multiple devices to use the internet at the same time.

If you only had a modem and you didn’t have a router in your home environment, you’d only be able to connect one device to the internet at a time.

Why’s that the case?

That’s because modems only have one ethernet port.

As an example, here’s what the back of my modem looks like.

As we discussed, there are obviously other reasons why you shouldn’t use a modem without a router, but could you imagine only being able to connect one device to the internet at once?

The majority of households today have more than ten devices connected to the internet at a given time.

Just think about having to connect a device to your modem every time you wanted to use it on the internet. That would be a miserable experience.

Routers fix this problem because they have multiple ethernet ports you can plug in to.

As you can see, my router has four ethernet ports. That means I can have up to four devices connected to my router with a wired connection. I can have even more devices wired to my router if I use an ethernet switch.

Those ethernet ports are just for the wired connections I want.

Did I mention that routers also allow for wireless connections to the internet as well?

A Router Provides Wireless Internet Connectivity

Routers are the reason you have WiFi in your home.

Routers have antennas on them that broadcast your wireless network signal through the air. Your devices can connect to this wireless signal and use it to send messages to your router. Your router will then send these messages to the intended destination. This is how your devices wirelessly connect to the internet.

Without WiFi in your home, you’d have to manually plug in all your internet devices to your modem for them to have internet access.

As we discussed earlier, you can only connect one device at a time to your modem.

Imagine how long some of those ethernet cables would have to be if you didn’t have a wireless internet connection. Your home would look like a rats nest.

On top of that, having to physically plug in a device every time you wanted to use it on the internet is like having to get up and turn a knob every time you want to change the channel of your TV. Not fun.

The good news is you don’t have to worry about that. With a modem and router in your home, you can quickly and easily connect as many devices as you want to the internet at the same time.

Hopefully you appreciate how your router makes life on the internet so much easier.

How to Connect Your Modem and Router

By now you should be convinced that a modem and router are both required for a safe and easy internet experience.

So what should your home network look like? How should your modem and router be connected?

Thankfully, this is pretty straightforward.

How to Connect the Modem to the ISP

First things first. Your modem should be connected to the internet that’s provided by your internet service provider.

There’s usually a port on the back of your modem labeled for your internet connection. This port will look different based upon the type of internet connection you have.

There are multiple types of internet connections available to you. In my case, I have cable internet.

As a result, this is what the internet connection on the back of my modem looks like:

Most modems will look like this because cable internet is the most common type of internet connection.

The cable that’s connected to this port on your modem comes from outside your home and is connected to your ISP on the other end. Your ISP will provide this connection to your house once you have an internet plan in place.

How to Connect the Modem and Router

The only other connection you’ll have to make from your modem (aside from the power cord) is the connection to your router.

Your modem and router will be connected by an ethernet cable if they’re separate devices. The ethernet cable to connect these two devices usually comes with the router when you buy one.

It should be pretty easy to identify what port the ethernet cable connects to on your modem and router.

Let’s start with your modem.

On the back of your modem, there should be a port labeled “Ethernet”. Unsurprisingly, this is where the ethernet cable goes.

It should look something like this:

On your router, there’s a similar port that should be labeled “Internet”.

This is where the other end of the ethernet cable is connected.

And that’s it. That’s all you need to do to set up your network properly with a modem and router.

Network Diagrams of What a Home Network Should Look Like

To help visualize what your home network should look like if your modem and router are separate devices, this diagram may help:

To make things easier on yourself, you can buy a modem and router combination device. If you have a combination device you only need to connect the internet cable (and power cord) for it to work properly.

Should You Ever Plug Your Computer Into Your Modem?

After spending this entire post explaining that you should never plug your computer directly into your modem, I must say I have a confession to make.

There’s actually one case where you need to plug your computer into your modem.

When you’re first setting up your modem’s connection to your internet service provider, you’ll have to plug your computer directly into your modem.

Upon doing so, you can register your modem with your ISP. This step is required to establish an internet connection with your service provider. You won’t be able to get internet access without doing this.

The specific steps you need to follow to activate your modem will be detailed in your modem’s user manual.

As a note, you’ll have to follow these steps every time you get a new modem for your home network.

To hammer this point home, this is the only time your computer should be plugged directly into your modem. You should never try to browse the internet without a router between your computer and your modem.

If the only time you plug your computer into your modem is when you’re setting up your modem, you’ll be in good shape.

Wrap Up

There you have it folks.
