Can I Use My Own Router with Xfinity?

Most users opt to go with routers directly from their internet provider, but it’s more than possible to use your own if you’re an Xfinity internet subscriber.

I have ample tech experience working with a range of different devices. That includes routers. My years of using them, as well as my years of using Xfinity, have allowed me to understand the options available to all internet users.

The following guide looks at the way Xfinity users can take advantage of both supplied and third-party routers by analyzing what works with the internet service and breaking down the pros and cons of going with your own device.

Key Takeaways

  • When using Xfinity at home, you can plug in your own router or go with the one that the company provides to you.
  • Using a third-party router allows you more control over your personal network, but it’s more expensive and makes upkeep more difficult.
  • Setting up an Xfinity router, as well as setting up a third-party router through Xfinity is a simple process that only takes a few easy steps.

Being Able to Use Your Own Router

When most people sign up with an internet service provider (ISP), they usually receive both a modem and a router from the company. Xfinity is no exception. The company provides you with all the tools you need to get started and run multiple devices in one home.

However, just because it’s an option doesn’t mean it’s mandatory. In fact, there are many users out there who don’t use the Xfinity-provided router with Xfinity internet. It’s more than possible to use your own model, as long as you get something that’s Xfinity approved.

There is a range of routers on the market, and they are all a little different. That’s important because not every device works with every internet. You should always first ensure that your device is compatible with Xfinity by checking their device info list.

Once that’s done and you know what’s available to you, you’re more than capable of getting any compatible router on that list. Pick one that falls into your price range, and always be sure to get something that comes with ample additional or beneficial features.

Buying or Renting a Router: Pros and Cons

Using a personal router with Xfinity comes with plenty of benefits, but it’s not a simple choice. There’s a real opportunity cost to not going with the provided item, and that’s something every user should keep in mind before going out and making a purchase.

The general rule to follow is that you should rent a router from your ISP if you want something that can be easily upgraded, or replaced, and that comes with ample technical support. You should use your own if you want to save on costs, or if you want more control over your setup.

It almost always tends to be cheaper to go with what Xfinity provides. That’s because they often will give you a wireless gateway, which combines both a modem and router into one package. Splitting that up can be an expensive endeavor.

Not only that, but Xfinity will help you when it comes to upkeep. Routers, like any piece of technology, diminish over time. Replacing your own can be a bit of a hassle, so it’s always nice to have a company that can come in and keeps you on the cutting edge for no extra cost.

However, you do lose a bit of control in that transaction. As you have to use Xfinity’s items, you’re at their mercy. If they provide you with an outdated device or something that doesn’t give you additional features, there’s not much you can do.

A private router gives you more control, but does so at a premium cost.

How To Setup a Router on Xfinity Internet

Once you know what router you want, the next step is to set it up. Though the process may seem daunting, it’s quite simple for anyone regardless of their technological know-how. 

If you get a router through Xfinity, there are only a few steps you need to follow. First, place the gateway in a central location of your house away from other devices. Next, write down your SSID name and then create a password. 

From there, use a coaxial cable to connect your gateway to the internet, plug in the main box into a power source, and boot it up. Finish by connecting the gateway’s internet signal via WiFi or ethernet, and then activate the internet. Once you test the connection, you’re ready.

On the other hand, if you want to use your own device first purchase an Xfinity-compatible router and plug it in according to the personal directions. Next, call Comcast (or use their app) to activate the device. 

Once everything’s up and running, secure your WiFi network and connect your devices to the machine. Set up your network name and password, then go back to each device and link them together. Return your old modem to Comcast and you’re good to go.


Here, I cover a series of top questions regarding personal routers.

Do I Need to Call Comcast If I Get a New Router?

While calling Comcast can be a way to activate your router, it’s more than possible to do it through the Xfinity app or on their website.

What Does It Mean if Xfinity Doesn’t Support My Router?

If you get a router that doesn’t work with Xfinity, it means it cannot be used on your home network. It won’t be activated and can’t connect you to the internet.

Do I Need a Modem and a Router?

While you don’t necessarily need both, a modem and a router are both critical if you want to connect numerous devices to the internet. Without either one, your setup isn’t complete.

Final Words

Using a provided router with Xfinity is an easy process, but it’s not your only option. Though most people favor the devices due to the cost and simplicity, don’t be afraid to use your own. To some, the extra control and power is more than worth it.
