I've been struggling with daytime packet loss here in Houston since early April. At this point my average packet loss is as much as 60% anytime between 7:30 a.m. and as late as 11 p.m. It affects anything I'm trying to ping beyond my /29's gateway IP. From the next hop onward, packets drop left and right.
Overnight, things seem pretty good. But during the day, I can't maintain a connection to anything. Phone calls drop, my office VPN disconnects, web sites stop responding… it's useless.
I keep calling in about the trouble. Over the course of all this, everything has been replaced: the cable to the tap on the pole, the grounding block, a splitter inside to attenuate the signal because it's a little too hot, all the connectors. On my side, I can leave a laptop plugged into the modem with nothing else connected, and the packet loss is just as evident. Nevertheless, I've gone as far as replacing my firewall. I don't know what else there is for me to do.
The last tech who visited was able to see what I was seeing, at least, and put in a call to plant maintenance. No word from plant maintenance though. Nobody seems to know what's going on or what to do next.
I've done a chat, seen two techs, and had at least one maintenance tech claim to have tried to reach me, but of course I have no record of a phone call. I do get calls from Comcast asking if they can close the ticket because it appears to have been left open accidentally. I explain that it is no accident.
What could be causing a problem like this? Is it likely to get resolved, or is this the sort of thing that just never gets fixed?
