Activate Custom Modem

I am trying to use the app to activate as that is what xfinity.com/activate is telling me to do.

On services all I see are TV&Streaming, but the Account Tab's xfinity plan details page says I have 75Mbps Internet and Tv & Streaming.

When I go to Activate -> "Your Own Modem" it says "You Need Xfinity internet to continue"


I am guessing theres some mis-syncing about what services I have purchased (just opted for internet last week and received the self install package (coax cord + Get Started card))

Wondering how I can activate

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.

Forgive me if this is obvious. To use the app to activate, you must disable WiFi on your phone or tablet. Your device needs to talk to the Comcast server via cellular data because your modem isn't provisioned yet.
