I purchased a new modem and after 30 mintues on the phone to get it credentialled got to a tech that I thought was going to help and then the call went dead. I tried just hooking the new modem to the coax, all the lights come on but it will not display the self credential web page. Is there a direct number to call to get a new modem credentialled? The first 25 minutes of the call was spent trying to get the support person to understand what I was trying to do and get me to someone that could help. It was an exercise in frustration
Connect it to the coax line and power it up. Let it fully sync up with the system ("DS, "US", and the "Online" lights are steadily lit). Connect a computer to it and open up a browser. You *may* see their "Walled Garden" modem self registration page. If so, follow the screen prompts. Have your mobile telephone number, your Xfinity username and password or the account number and telephone number associated with your Comcast account handy.
If not, try calling 1-855-652-3446. That is their device activation line.
If that doesn't work for you, you can call 1-800-comcast and tell a rep that you would like to have a new modem provisioned for service. Have the RF / CM / HFC MAC address and the serial number of it handy when you call.
