I'm having an interesting problem with my web browsers (Firefox 2, and Internet Explorer). After a few minutes of working fine, if perhaps a little slower than normal, they stop being able to connect to the internet at all. I've tried using a few other applications capable of internet access after this happens, and some of them can still connect, even while my browsers are proclaiming my network unavailable and timing out. I recently installed AVG Security Suite, but disabling the firewall doesn't seem to have any effect on the problem. I've tried reinstalling my network drivers to no avail. I've tried reinstalling Firefox, and running both browsers in "safe mode" with addons disabled. A side note, I uninstalled Zone Alarm when installing the AVG Suite and the uninstall didn't go smoothly, leaving the TrueVector service on my computer. When enabled, I get nearly no connectivity (I think anything I didn't approve through Zone Alarm back when it was installed is blocked). When TrueVector is disabled, I'm where I am now.
A short list of programs I know do not connect when this starts happening:
Steam Client's integrated web browser (The updater, etc appear to work fine)
Unreal Tournament (Crashes when I try to run the server browser)
AVG Suite Updater
List of programs I've seen still able to connect to the internet
Pidgin IM - I know it works because I can still send and receive messages
Xfire IM - same as above
World of Warcraft - Connected to my realm
Enemy Territory: Quake Wars - Connected to several multiplater servers
I'm on Windows XP, SP2. This problem will not appear until I browse the internet for a while. There doesn't appear to be any pattern to the sites I'm at when the problem manifests. Again, the measures I've have tried are reinstalling Firefox, reinstalling my net drivers, restarting my network adapter when the problem pops up, and disabling my firewall when said problem happens. None of these things seem to have any effect. The only thing that does anything is rebooting, which works only until the problem comes back.
