Internet drops for 30-45 seconds throughout the day for last two weeks

Cox Core Technology Tech has been out to verify no issue with my modem or wiring. He said there is issue with noise in the signal. He sent a Field Service Technician out. Unfortunately before he could research, he was called away to an outage in another part of Phoenix. Before he departed, he left a note that said "There is a neighborhood issue related to noise/ingress. It is usually from homes" He said he'd be back that day or the next to research and fix. That was nearly a week ago and I haven't heard anything.

I called Cox yesterday to inquire. They sent a representative out this morning. He wasn't a field service person, and only told me that he was aware of tickets open in the neighborhood but couldn't give me any information on when the issue may be fixed. He left after a five minute conversation.

Hoping a Cox representative may be able to research and provide more information on what's going on and the expected resolution time. I've pasted some information from my cable modem for review by those who may be knowledgable in that regard. Any help is appreciated in advance. (Note: I last rebooted about 14:30)

Looks like T3 time-out errors, probably from the noise on the upstream the tech hasn't isolated yet. My guess is you got the upstream OFDM channel around the time you had these problems. I would suggest emailing Cox at cox.help@cox.com with your account info and a link to this thread and ask for a update. Hopefully someone will be able to track down a ticket number for the work. If not, they may have to start all over again.
