92108 area connection problems - Time Warner Internet

This question is about "92108 area connection problems", with Time Warner Cable internet and apps. I figure this is Charters problem but I can't rule out my modem end yet. If it was Charters end, wouldn't they know about these bad stats? I figure I would give Charter a few days before I call again. Going through the "is it plugged in" stuff is annoying. Connection has been sporadic.

This topic covered 92108 area connection problems, and TWC cable internet service.
