reference: ARRIS SURFboard T25 DOCSIS 3.1 Gigabit Cable Modem bought from Amazon
Xfinity has not fixed or identified any issue on their end. I’ve spent two 3 hour sessions with their support computers, techs, and elevated support. Xfinity support confirms we have the latest firmware, and have reset the modem many times as have I. I’ve tried several phone systems that perform on other systems as they should. (panasonic and Vtech). I’m reaching out to see if this is an issue with the T25 itself, as I have really run out of things to try.
Any help, direction would be greatly appreciated.
