CM400 Cable Modem
Can someone help me. My modem keeps losing internet connection. I purchased it in January, 2020 and it worked fine for 2 months. I've rebooted, reset, etc and it will not hold the internet connection....
Log into the modem and get a screen snip of the cable connections page showing all the upstream/downstream info and post it back here.
Also the logs.
Also, remove any splitters, amplifiers, attenuators in your line. These can cause issues. (sometimes fix them too but usually cause the problems).
Are you sure its the modem? How do you know?
