My parents have been having a hard time with their wifi range, so I made plans to replace their Netgear c3000 cable modem w/wifi. I was using a Netgear C7000v2 at home with no problems (also comcast...
Comcast does a great job of blaming everything on the modem (if its not theirs) or a house. They'll do whatever they can to not admit its on their end.
Hook up the modem and take a screen snip of your modems connections page. It should lock at least 1 channel for activation. That'll at least show us a baseline power level.
I've had to argue with a tech before because he kept saying it was a modem issue because their docsis 3.1 device connected and worked. docsis 3.1 is a little more tolerant of power flucutation for activation. If the level is to high or low, it'll cause issues.
I ended up buying an Arris modem/router/wifi device which is docsis3.1 and it works wonderfully. Yes I believe it was a power fluctuation issue. Thanks for letting me know 3.1 is more tolerant of these, but I should still clean up the power. Thank you.
