Disconnecting Constantly Ever Since Snow Storm
I've been using a personal modem (Netgear CM1200) for about a year on 400/25Mbps (483/22 actual) service for about a year now with no issues. I didn't lose internet during this recent snow storm until about 2 days afterwards. It's been a week since the storm and I'm still having issues after a tech visit.
A tech came out about 4 days after the storm and said that the signal became too hot. He added more pads. 12dB total I believe on the downstream and a few dB on the upstream. I didn't see the upstream pad he put in. He thinks Spectrum turned up the power after the storm to compensate for other people's issues. I'm near the end of the line and my signal is too hot apparently. Doesn't sound like a bad problem to have normally.
We looked at my modem power levels together and he said it was ideal like this (-0.8 to -3.9dBmV downstream.) Obviously it's coming in about 12dB higher until his 12dB pad so he could have had it higher if he wanted. The previous tech, who came out to remove an old Time Warner cable tv filter from the pole, said the same thing about these levels. Both techs had agreed I was good to go to run 980Mbps service.
Here's some info on my system. Desktop gaming pc with 10ft CAT8 to Linksys EA9500 router with 1ft CAT8 to Netgear CM1200 modem (personal) with ~30ft RG6 to ~180ft RG11 to Spectrum outdoor box on the pole. Tech replaced all coax connectors for good measure although he tested the line from the modem out the spectrum box and said everything was "Great."
Below is the data from my modem including all levels and error log. Please take a look and see if there's any obvious problems. Any help is appreciated. When the internet goes down I log into the modem and see that the upstream channels 1 & 2 are unlocked. I can send more information as well if needed.
