Xfinity with Voice / Phone / Triple Play Approved DOCSIS 3.1 and 3.0 Cable Modems

Below are all the modems with phone capabilities that Xfinity has approved for their residential customers to purchase and use on their network, as of November 2022. Xfinity lists them on their website here: Xfinity Approved Cable Modem List. Prices below are updated every hour. 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, Walmart or eBay. (We only show new eBay modems that can be returned and have free shipping.)

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 seven months. It’s easy to install. Just hook up the modem, and activate it on the Xfinity App: Xfinity Activation Instructions

Comcast for Business Phone / Voice Customers have to rent a cable modem from Comcast.

If you need further help with your decision or understanding some of the terms, see our Cable Modem Buying Guide.

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. If you want to future-proof your purchase, as speed plans inevitably get faster, we suggest selecting DOCSIS 3.1 from the DOCSIS menu below.
