Xfinity Approved DOCSIS 3.1 and 3.0 Cable Modems

Below are all the modems that Xfinity has approved for their residential customers to purchase and use on their network, as of November 2023. Xfinity lists them on their website here: Xfinity Approved Cable Modem List. There are over 70 different modems on that list, and we’ve gone through all of them to find the ones that can be purchased at Amazon, Best Buy, or Walmart. Prices below are updated every hour.

If you’re paying $14 a month to rent a modem from Xfinity, that’s $168 a year, or $840 over 5 years. You can buy a new one that will pay for itself in less than four months. It’s easy to install. Just hook up the modem, and activate it on the Xfinity App. Read more at Xfinity here: Xfinity Activation Instructions

Xfinity/Comcast Business Customers: See our Comcast Approved Modems for Business page for supported modems.
Xfinity Voice/Phone/Triple Play Customers:  See our Xfinity Approved Modems with Phone page for supported modems.

Select your Xfinity speed plan below. If it’s not listed, choose a plan that’s higher than your current one. This will allow you to get the maximum speed out of your plan. Next, decide if you want a modem with a built in Wi-Fi router and what type. If you want to future-proof your purchase, as speed plans inevitably increase, we suggest selecting DOCSIS 3.1 from the DOCSIS menu below.
