    This modem has been working great for me. I am getting consistent 950mbps numbers on this router. I just wish it had its own on board wifi and a battery backup for the price you are paying.

    This modem was a fantastic replacement for a defective unit. It works wonderfully, and being an approved XFinity compatible device, it was easily added to the account.

    This cable modem has been working well. I've been consistently getting over 700 Mbps using Xfinity gigabit. It's nice to have the phone port to use with the Xfinity service as well.

    i upgraded my xfinity speed to 600 mb/s? due to the rapidly growing list of wifi connected stuff in our home, and c/o slow xbox connectivity from my son... so, i needed to upgrade my modem otherwise i only got half the benefit from the increased xfinity speed. it's always a little bit of a chore to switch to a new modem, but wow! doubles my previous "blast" speeds! no more c/o from my son! my second arris modem, they work great!

    Replaced my current Comcast modem with this in order to take advantage of their higher speeds that require DOCSIS 3.1. Setup couldn't have been easier.
