Comcast XFINITY Approved Modems

View the numerous Comcast XFINITY approved modems, but it is easier to look at the list below for the top recommended modems. Three categories (value, WiFi, and DOCSIS 3.1) help to sort the many options for Comcast XFINITY internet services.

Read the Cable Modem Buying Guide to help you choose a modem. Do not forget to purchase your modem accessories.

Internet providers have begun removing some DOCSIS 3.0 modems from their networks. To maximize the years of use from a modem, it is strongly recommended to purchase a DOCSIS 3.1 device (the latest standard).
