Constant T3/4 errors
Constant outages for the last several months, T3 and T4 errors in the logs each time. Never had issues except when maintenance was performed, then a round of cox trucks came in the area and we've ha...

Is the RG6 direct to the modem or are there any splitters in the house or outside? T3 are caused by ingress in the upstream. See here for more info. Also, can you post your signal levels? Should be available at 192.168.100.1 if a stand alone modem. Looking for high upstream that might be part of the T3 problem. T4 are either caused by consecutive T3's or issue with the downstream stopping. As for what you have to do, if you have ruled out inside wiring, schedule another tech. If more then 3 techs already in the last month, file a informal FCC complaint to get some attention.
dBmV ranges on downstream from -0.7 to 4.5 currently, mostly in the positive 3s and 4s, SNR is between 40.1 and 42.5. Other times I check dBmV is between 4-10. Channel 33 though, OFDM PLC at channel ID 159 has 1,333,331,855 corrected errors, and this is with a 17 hour uptime. Refreshing the page right after, 1,340,910,085 errors. Last tech that came by said downstream should be roughly -10 to +12 and no more or less
Upstream channels are 46-46.8 dBmV. That seems excessively high, but I am unsure what they're supposed to be.
The RG6U runs from the cox box on the house to the bedroom directly, then terminates with an F type compression coupling in a faceplate, then direct to modem. This setup has been flawless for years.
We had a TPLink router that suddenly kept rebooting, and when we thought the router was dying, replaced it with a Motorola, then that didn't resolve (it cleared up for a couple weeks then right back at it) and we filed warranty for the Motorola modem. Then it was fine the whole time the modem was shipped.
Sometimes it's good for weeks on end without issue, then all of a sudden it's constant back to back. I got tired of dealing with the tech support and have dealt with it hoping it would clear again.
