I read you are resetting everything. As such you haven't found the issue.
Start with your PC. Yes/No?
Then the next part (router) Yes/No?
Then the modem. Yes/No?
Keep track of what part fixes it and then replace that part.

This just started happening about 2 days ago. I'll be online (always online with cable internet) and the internet connection will just die, I'll have to reset the modem, router or the computer to get it back online. As far as I know it?s not my ISP (Road Runner San Diego.) Their network does go down a little too often but they are pretty good about informing their customers, since its after hours I can?t call them. I'm using a wireless router with the main computer connected thought an eithernet cable (other comps use the wireless feature.) Im running ZoneAlarm 4 with a home network established, the firewall zones are all set up exactly the same as they were when the internet was working fine. As for the cable modem it does one of two things. One, it either resets on its own (this usually happens when RR screw with something at their end) or two, all activity stops but according to the modem im still online but according to the router I'm not (this is probably just a refresh error.)
If anyone knows if this is something at my end or a problem with my ISP please tell me, and how to fix it.
