Best Comcast Xfinity-Compatible Routers and Modems

To Xfinity and beyond?

Looking to escape monthly router fees? It's high time you bought your own networking equipment. But before you buy that new router, we need to make sure it's Comcast-ready.

Thankfully, we've taken the liberty of compiling a list of the best modems and routers you can use with Comcast Xfinity!

If you'd like to check if another device is Comcast Xfinity compatible, you can see if it's listed in the My Device Info database.

Why purchase your own modem/router?

There are many reasons to purchase your own Comcast-compatible modem or router. Most compelling is avoiding monthly equipment rental fees.

For example, if you currently pay $10/month to rent a modem from Comcast, you can buy your own -- and in 6-12 months, it will have paid for itself, lowering your bill by $10/month.

  • Direct access to control your network
  • Circumvent tech support to adjust router settings
  • No Xfinity Wifi broadcast
  • More secure
  • No monthly equipment rental fees!

Do I need a modem, router, or both?

A modem converts the raw signal from your Internet Service Provider (ISP) into something your computer can interpret. For Comcast, you need a special compatible cable modem.

A router (commonly a "wireless" router) creates a network that transmits the Internet connection from the modem, allowing your phone and computer to access the Internet. This is where your Wi-Fi network comes from. Generally speaking, just about any router will work with your modem.

A modem/router combo combines the connectivity of a modem with the wireless capabilities of a router. This is the most convenient type of gateway since you won't need two separate devices.

Since almost any router will work with Comcast, in this guide we'll cover the top Comcast-compatible modem/router combos and modems.
