  1. I purchased the Arris model SVG2482AC as it is listed in the above reference as one of the approved modems. I called Comcast and requested help to get it connected, I was informed this modem is not compatible with the xfinity and that I needed to return it to get a refund. Why do you have it on your list if it is not compatible?

    1. Either Comcast lied to you or you may be in an area that is slower to certify devices for your local network. If you look at the product box in the link below, it states that the SVG2482AC is approved for XFINITY service. In fact, Comcast is the only ISP that has approved this modem/router/voice device.

      The ARRIS SVG2482AC is an approved modem for Comcast XFINITY service. You may want to call again to speak with someone else to try and activate your device. Sorry that Comcast put you through this inconvenience.

  2. Do you know if any new DOCSIS 3.1 modems are expected to hit the retail market any time soon? I’m interested in upgrading to DOCSIS 3.1 (especially since Comcast nearly bricked my DOCSIS 3.0 in April via some “upgrade” to gig, which required us to spend an hour with tech support to partially fix the problems it caused), but if a new gen of 3.1 modems is likely to be released soon, I’d rather wait. Thanks.

    1. Sorry, no news on any new next-gen DOCSIS 3.1 modems. Current-gen DOCSIS 3.1 modems are still relatively new (many ISPSs haven’t even upgraded to gigabit speeds yet).

      Keep in mind, most people don’t have access to gigabit speeds (expect that to take a few years to achieve). That really needs to happen first before several generations of DOCSIS 3.1 modems pile up.

      Officially supported DOCSIS 3.1 modems for Comcast XFINITY today are:
      ARRIS SB8200
      Motorola MB8600
      NETGEAR C7800
      NETGEAR CM1000
