I used my Netgear CM400 until January 2018 at my old address, but when I tried to use it on new account, I Cannot connect to internet. It connects to the Xfiniti network and it gets a, IP address assigned, but no Internet access. Is it possible the MAC address has to be assigned to my new account?? And how do I do that ?? Any info would be great . . . THANKS
Call 1-800-comcast and tell a rep that you would like to have a modem provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
