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 had constant issues since. Replaced the modem without improvement, Motorola worked with me for weeks and came to the resolution Cox needs to get their stuff together and fix it. Tech came out and the only issue he saw was the signal was a little too hot, so we put a damper on the line and that didn't help anything.
Motorola then said constant T3/T4 errors would cause a modem reboot in a last ditch effort to establish connection, something primarily with T4 errors and reprovisioning attempts. All my attempts to reach out to Cox has been laughable, they immediately want to reboot the modem (its always been rebooting when I call or chat) or send a tech to my home and bill me for cable replacement - brand new RG6U that worked fine for years. Never had issues till one of their techs messed something up down the line.
Now it reboots several times a day and night, and our work from home keeps getting interrupted. Last speed test results 38ms ping, 383.6 down 9.8 up, and 3 ms jitter. Speeds are fine till it cuts out. No complaints otherwise.
What do I need to do to get someone to fix this junk?

similar issues with my line for 3 months. I'm installing T-Mobile 5g home service tomorrow as primary since my router can handle 2 WAN connections, even though I've finally managed to schedule a tech after all this time and all of their outsourced run around that have no idea on Cox policy or US laws. I plan on degrading my Cox service as secondary WAN until they get their act together. or that fibre line that's only a couple of blocks away gets pulled. the funniest part, while I was in the T-Mobile store, I explained why I'm interested in their home connection, apparently the are required to have a hardline cable, but have had nothing but identical issues as mine for months too. it's annoying to see team viewer notifications of all the work computers I monitor, also randomly come back online, both my work and T-Mobile store are only blocks away so it's a widespread issue, yet Cox does nothing.

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.

I have replaced the 1 barrel jack connecting the outside line to the inside line and still no change. Peak SNR dropped by 0.1. It could be back up later. In the 9 minutes and 23 seconds uptime after changing the barrel connector, there have still been over 17 million corrections on OFDM PLC. Guess I will consider replacing my good RG6U with more RG6U before telling them to get on their own stuff and fix it.
