I'm usually gaming wirelessly from my laptop, but when I lose internet access I remote to my PC which is cabled to my router to do some testing. I've also tried connecting my PC directly to the cable modem (entering the static IP etc) but alas the problem didn't resurface during that trial and I hate leaving it connected directly for any length of time.
I replaced my wireless router several weeks ago, this problem was a good excuse to update, but sadly it didn't resolve the issue.
So last night my connection dropped at 18:58 and again at 19:42, for several minutes each time. This morning I awake to find zero access again, and the modem still saying online. My iDevices tell me the last time they were able to sync email was 23:57 so it's been down the rest of the night.
Perhaps stupidly, I power toggled the cable modem before giving TCL a ring, because 2 minutes later I have internet access again. The tech says he can see no recorded dropout from my modem at all overnight however. I have remote access programs (Splashtop and LogMeIn) on my iDevices, and when I lose connection I cannot see my PC from outside (via XT), but in a nutshell, he couldn't explain loss of connectivity when the online light is still on. I haven't been able to explain it either for several months, so I've asked for a modem replacement, and will probably have to pay the $80 callout fee.
Has anyone else come across this problem? Any other ideas I could try?
