We have Comcast, this modem is supported by Comcast and it’s super easy to set up. It took less than ten minutes. If you have Comcast there are specific instructions to set it up. Very easy. The modem works so far. Our internet speeds are where they are supposed to be.
Stop renting your modem and buy it!


Since hook up from 2 days ago this is the numbers I am getting (see picture). I am not a tech geek and was hesitant but this was fairly painless and now I no longer need to lease a provider controlled modem that costs $10 a month that you generally talk to a automated response when you have problems.


Just unwrapped my CM1200. I unplugged my old modem; disconnected my WiFi router and then connected and powered up the new modem. I had to call xfinity and have them add the MAC address and send the reboot signals because the web activation didn’t work for me but after that, I reconnected my WiFi router and everything worked as expected.
