The Best Modems and Routers for Xfinity

To use Xfinity internet, you’ll need a compatible modem and router. You might think a modem and a router are the same device, but they are not. Simply put, a modem is a device that connects your household to your service provider, in this case, Xfinity. A router connects to the modem in order to create a Wi-Fi network in your home that your computers and connected devices can use to access the internet. Modems and routers can be purchased separately, or you can use a device that combines the two.

If you’re signing up for Xfinity service, you have two options: rent a modem and router for a fee of $14/mo or purchase your own. While you might take comfort knowing that the Xfinity-provided device is compatible, it’s important to note that the rental will cost you about $168/year. For around that amount (sometimes less), you can buy your own compatible equipment to use with Xfinity and save yourself hundreds of dollars of rental fees over the next few years.

To help you find the best modem for Xfinity by Comcast, we’ve compiled this guide to provide you several options to consider.
