internet connection drops daily and tech visit fee
I am experiencing internet connection drops on a daily basis, each drop lasts about a few minutes. This causes a lot of issues with work from home. I rebooted cable model and router many times and none solved the problem. My friend on the other end of the street didn't experience the issue.
I checked the event logs from the cable model (Arris S33). They showed very frequency T3 timeout (every minute, see sample logs)

I looked up the internet and found that most "T3 timeout" issues are related to the coax line signal noise, which requires a technician visit to address. I then chat with an COX agent and asked whether they could send a technician. The answer was yes but I could be charged $475 fee, quite absurd frankly.
Does anyone have experience on fixing the "T3 timeout" issue? What is typical fee for tech visit?
Thanks.
