cable modem losing sync every night
I'm just looking for some tips here I guess. I've got Charter HSI+, which is a 16Mbps connection. Works great when it works. When it doesn't, good freaking luck getting help from Charter (you probably know this already if you are a Charter customer)
So my modem all of a sudden started losing sync every night around 9:00pm and continuing to lose sync, resync, then lose again every 15 minutes or so until roughly 4am. After that point, I get a good 12 hours of uptime as verified by my cable modem logs, but then as night comes the next day, same behaviour.
I've had 3 Charter "technicians" out so far to fix the problem. The first one said although my signal levels were acceptable, he'd like to see them better. So he replaced some coax in my house feeding my cable modem. No signal improvement was seen, so he had someone adjust the amps. Problem wasn't resolved, so I bought me a new modem hoping for luck there. Same thing happened.
So a 2nd tech was sent out, who claimed it was probably because the system didn't have my new MAC address. Ok I guess, I let him go. Sure enough, no change in reliability.
3rd tech came out, I gave him the story, told him feel free to check all signals, but they were fine. He pointed to a splice in my overhead line as the problem, and had a higher up tech come out the next day to fix that. I was hopeful this time, but saw no help.
So I'm stuck at roughly a month now of this crap service. I can't even browse the internet with my cable modem during the nights. I'll click links and pages will just stop loading. I'll be watching video and the streams just die. It's ridiculous.
I really don't know what to do at this point, and it's becoming clear that no one in Charter Tech support does either. I have no other options for a fast broadband pipe like this, so i really would like to see the issue resolved rather than switch to another provider. DSL only gets me to 3Mbps in my area, and Uverse isn't here yet.
So I post this in hopes that maybe, just maybe, someone out there has a clue on what could be going on, or what I could say to the cable company to motivate them to find the problem already. I'm tired of guys coming over to replace splices and coax in my house when that is CLEARLY not the problem.
