MoCA Not Working After XB7 Factory Reset

Before purchasing a moca adapter I did my research to ensure the XB7 modem was capable of the functionality. I logged into the XB7 and verified moca was enabled and the moca icon on the top-right corner was green. When my adapter arrived I connected it and it worked right away. It was working perfectly until I performed a factory reset on the XB7 because I had forgot the admin password I set. Now the XB7 moca feature will not work at all. When I log back into the XB7, it now shows it’s enabled but the moca icon on the top-right still has a red “x.” I’ve rebooted the XB7 dozens of times and even did a reset on the adapter. No resolve. I wholeheartedly believe the issue is the XB7 not fully initializing the moca feature even though it claims to. I tried to call support for help but the support options are restricted to hard downs, intermittent connections, or slow speeds. I am frustrated that I can’t talk to anyone to help me with this unique problem. Please help.

I was finally able to get my issue resolved today. MoCA is functioning after I swapped the xfinity modem out entirely. I had the XB7 but upgraded to the XB8 because there was no up-charge for it. Either the XB7 modem was defective or there was a configuration bug of some sort.

Update: I just attempted to connect the moca adapter directly at the dmarc in my basement. Still no MoCA :(
