Brand new Motorola MB8611 modem. App won't find.

I've tied to register the mac address of my new Motorola MB8611 modem using the app and, after 11 minutes, the app says that it can't find it. My old modem, a CM500-100NAS, still works fine so I know that it's not a line issue.

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.

Can you access the web interface on the modem and make sure it's locking onto the US/DS channels as it should?

Yes, it does lock onto the channels.

@EgillSkall​ Another way to activate would be to open up a browser with a PC connected to the modem and activate that way. How I did it the first time with a SB6183.

Tried that. Opening a browser just brings up the typical no internet connection error....
