Errors: Unicast Maintenance Ranging - No Response received - T3 time-out;
Having intermittant problems with my connectivity - drops about every 20 minutes, green light to the cable signal goes red - have to reboot to make it work again, and the loop continues. Own cable modem and separate router. Netgear CM500. Comcast Xfinity performance 75. Had the modem / contract 3 years, been rock solid, but last three days problems out of the blue. No changes in my internet network or devices, although construction is occuring in my area (related?).
Adding some images of the errors from my cable modem. Am technical, but not about hardware.
I am worried about booking appointment from Comcast as they might charge me if it's my modem at fault. Anyone decypher these logs?
