Re: Intermittent packet loss starting in the evening.

I've been experiencing intermittent connection issues since the start of the pandemic, and having exhausted all other troubleshooting avenues, I've arrived at a hypothesis - that Comcast's backend is simply not tuned or built up to manage the additional usage posed by the number of people working from home. The commonplace is that for all the fee hikes Comcast has been levying on its users over the years, very little of it has gone back into building up its infrastructure. Some argue that Comcast sees the writing on the wall for its cable service with the advent of 5G so they aren't going to bother sinking more money into it - their future is more tied to the Peacock (NBC) than the wires. 

 

I hope I am proven wring but I think this kind of spotty service is what we're in for for the duration fo the pandemic.

I called Comcast and they sent a tech out.

 

Turned out a squirrel had chewed on the cable up near the pole. He replaced the line and I'm happy to report my issues seem to be resolved (it's been about 5 days).

Thank you, that is good info. I’ve pretty much done all that plus had the line from pole replaced. Hey, I’m not anti-Comcast, but it is just a company. We can point out where it’s weak.

I've done most of the things on that list, including testing with multiple different PCs. These are the signals I have with the modem in my living room. This is after a technician came and removed a splitter that was right before the modem but it didn't fix the problem. I have also tested it connected directly to the coax that comes into my house in the attic and it did not make a difference with the packet loss issue.

Then get a tech out to investigate / correct the problem. Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.
Good luck !
