Ok, first off I want to say that I re-formatted my hard drive and reinstalled Windows XP SP2 about 6 weeks ago, so I don't see why there could really be a problem0, but there is, and here it is:
When I return to my computer after a long-ish period of time, say anywhere from 2-5 hours, my internet will not work. It is not set to hibernate or go into standby. I have a cable modem and it is connected to my computer with an ethernet cable. Windows will think that everything is fine and there aren't any errors telling me that the internet is acting strangely, but I cannot get anything to work that requires a connection. AIM will not log on, programs like Adaware cannot check for updates, Firefox can't load anything, etc.
It started doing this around 2 weeks ago, but before that when I would come back to my computer after several hours the internet would work just fine like it should. I have also not changed any settings that I can think of that might make this happen......
A simple reboot will make it work fine, but can be quite a hassle doing a few times a day.
