Re: [TWC] Upstream Power is +56.5 dBmV, please help.
Sorry, but I must disagree. Adding more splitters will only INCREASE the upstream power, which is already too high. The solution is to decrease the number of splitters between where the cable enters the house and the modem's input (ideally, you only want one splitter in the path here).
If the upstream remains above 50 dBmv with only one splitter in the signal path, a tech will need to come out.
