Re: [GA] My Cable Service
It sounds like noise ingress into the line, which an older meter is not going to detect, MCCShawn's suggestions are correct we need a QAM meter that can actually decode the QAM frames and determine what is wrong. If I had to guess the signal is probably fine (if adding an amp didn't help) but the SNR is probably too low due to the noise ingress. The bad news is that can take a long time to solve because they basically have to work backward from your home to the cable plant to find where the ingress is.
I wish you good luck but there is a lot more to a CATV HFC network than an ethernet network.
