Re: High Upstream Power T3 Errors - Frequent Disconnects
Levels are fluctuating and channels are dropping. There is an Arris NIU and an amp installed by Cox on the modem leg. My set top box also shows high upstream...going from 45 to 56 dbmv. Attached are the levels from this morning. Soon afterward channel 1 dropped.High Upstream Power T3 Errors - Frequent Disconnects
For over a week now the upstream power on my cable modem randomly varies on all 3 upstream channels. I tried putting my old Docsis 2 cable modem online and it also had an upsteam power problem. I had a tech out who could not find any ingress on any of the lines. I suspect a problem outside of my house. What is the next recommended step to resolve this problem.
