Brand New ARRIS SBG10 Gateaway cannot connect to Comcast Internet
I bought a new Arris SBG10. I have talked to Comcast customer support and used the Xfinity app to register the new gateway. I have correctly added the MAC Address for the new gateway and made sure every connection is “finger tight”. After 11 minutes the app times out and will not accept the new gateway. I have tried this a number of times.
I am pretty confident that there is nothing wrong with the new SBG10.
It appears to me that somehow Comcast is not accepting the MAC address of the new Arris SBG10 gateway. Is the MAC address of the new gateway not being accepted by Comcast for some reason? Please help.

Connect it to the coax line / outlet and power it up. Let it fully sync up with the system. Check that the front or the top panel indicator light(s) is / are steadily lit.
Then 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 self-install 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.
