I have Windows XP with all the latest updates. My problem is that intermittently my computer disconnects itself from the internet for no apparent reason. I'm on DSL and my network stays connected and I still have my LAN icon in the task bar but the only way I can get back on the internet is to reboot my computer. This is an intermittent problem and happens no matter what software I'm using (i.e. IE7, outlook express, downloading something, etc.) and will even do it when the computer is sitting Idle. I may go 2 to 3 days without any sign of the problem then suddenly it will do this a couple a times a day. I don't have any idea where to even start looking to solve this problem so any suggestions would be appreciated.
