Internet activation

You need to go into the Xfinity app. When you log in there should be an option for activating equipment. After that it's pretty straightforward 

Some other options;

If the front or the top panel indicator light(s) is / 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 self-install device activation line.

If those don'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.
