    Works great. Decent speed. Works very well with Xfinity. Have to have everything in line before activating properly. Must be in line with the router first before registering with Comcast.

    As expected and better than the provider's hardware. No issues setting up once I learned you do not actually have to have the provider do this on the phone, you can use their website.

    Awesome modem which is using Doxysys 3.1 technology and is capable of supporting 2.4 GBPs speeds if your ISP is capable of supporting that high speed. Plus, it’s at highly affordable price.

    Decided to purchase this cable modem instead of renting from the ISP. Much faster than one from the ISP's router/wifi router unit. I am very satisfied with motorola cable modem.

    Pricey, easy “plug’n play”. Unfortunately the actual problem turned out to be a bad cable in the yard, but my old modem was obsolete anyway, so I would have to replace sooner or later
