Settting up New Modem
I got the new modem. How do I set it up without a cell phone? Its been sitting on a shelf for weeks. I can't find an answer. I'm thinking its time to take it back to the store and use my current, working, network. The only link I found in the forum basically said, use a cell phone.

So given the automatic reflex to answer with the link I addressed in the original question as not working and the silence since can I assume that one cannot have an upgraded Xfinity internet unless one also has a cell phone?

When you connect the modem to the coax, connect a computer with an ethernet cable to the modem. Turn on the modem, then the computer. Follow the prompts on the screen.

Connect it to the coax line and power it up. Let it fully sync up with the system, and check that the front / top panel indicator light(s) 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 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.
