14 Modems You Can Use with Comcast Xfinity to Save Money

So you've got internet service with Comcast Xfinity but have made he financially sound decision to go with your own modem instead of renting one. Good for you, pat yourself on the back for taking matters into your own hands. (And, yeah, doing a little bit of math in the process.)

But you can't just pick up any old modem off the shelf. You're going to need one that's compatible with Xfinity's network. And in addition to that, you'll want to make sure you're picking up at least a DOCSIS 3.0 modem. (What's DOCSIS? Fine, it stands for Data Over Cable Service Interface Specifications. And DOCSIS 3.0 is the bare minimum you should buy at this point — DOCSIS 3.1 would be even better and give you a little future proofing.)

The good news is you don't have to guess at which modem to buy to work with Xfinity. They've got a perfectly handy list of current modems (opens in new tab) — some of which double as routers — which we present to you here:

Which one is best for you? Look, that's kind of a personal question. You're expected to do your homework on each and every one of them. Go on, we'll wait.

Or just choose at random. Your call.

Should you rent or buy your cable modem?

  • I'm about to buy the one from Asus, would you recommend Asus or that router in particular?
  • Does these work with their Gig plans too?
  • On thier gig plans you have to use thier modem. I know this because I bought my own modem and they wouldn't let me get anything above the 250mb plan (next plan up is gig) even though the modem was docsis 3.1 and supported speeds way faster than a gig. Pure BS
  • Any modem with an Intel Puma 6 chipset is an automatic fail and should not be recommended! Google It!
  • I'm waiting from Asus respond about it...
