Recently upgraded from a SB6141 to a CGM4140COM/XB6.
After a couple hiccups, and resetting the new Gateway a few times I was able to get everything activated and get the xFi app working.
A few days later however, now I'm being greeted with the "To access xFi, you'll need to upgrade your service/equipment." error message when attempting to go through the App or through internet.xfinity.com
I've tried removing and re-installing the app, and restarting the modem but the error message continues.
Thanks in advance!
My apologies for the time between your post and this reply. We had many issues around this time with the app as there appeared to be an outage of service with the app. Would you please let us know if you are still having issues and we will work to get them resolved. In the meantime, I hope this finds you and your family well.
