New Motorola MT8733 not able to add this modem to my Xfinity service

Just unwrapped the new Motorola MT8733 connected up the COAX and network cables. Then went on the Xfinity App and Selected Active a Device / Your Own Modem; entered in the CM MAC but the Agent could not get the MT8377. After many times turning on and off the device / Agent to resetting it we gave up. Then reactivated my existing Xfinity cable modem plugged in the COAX and network cables and everything works fine. Any ideas on how to get this new Motorola box connect to the Xfinity network?

You're probably going to have to call Xfinity.  Did you voice call previously or use a text chat function?

Already called Xfinity and they could not get it to work.

@TS_2 Hey there, could you please confirm if that modem works with the account and location? If that exact model shows, please let us know.

Please create a new topic of your own here on this board detailing your issue. Thanks. The original poster has not returned. 3-month-old dead thread is now being closed.


For future reference, it is better to submit your own post as it creates a ticket to get help, and posting on someone else's older thread can delay getting help.
