C6900 upstream light blinking
Hello, the upstream light is blinking, is that normal? If not, how to fix it. thank you!
here's how to get the event logs:
Check your cable and make sure there isn't any splitters. Technically your power levels are in spec and you don't have errors but you're borderline and the upstream might have more resistance causing it to not lock enough channels.
Thank you for helping me!
I don’t have any amplifiers, signal attenuators, or splitters. I connect the modem right where the coax comes into the home.
please see below and let me know if you can see any problem:
