I have a strange problem. I lose access to the internet via certain programs only at random times throughout the day and for time spans ranging from a few seconds to several hours. Firefox, IE, Chrome, Live Messenger, Windows Update lose their connections. Meanwhile Outlook, certain other automatic updaters still have a connection. When I "lose connection" it still shows me as connected, and I can ping any site on the internet through the command line, but none of the above mentioned programs are able to connect. To be more specific, let's say I try to surf to Google in Firefox, it will show the "loading" icon until the connection comes back, even if it's several hours later. I have tried disabling the firewall, updating drivers, etc. Ipconfig release, renew, etc. seemingly has no effect whatsoever. Strangely, I have a Windows 7 virtual machine that can access the internet without issues, while the underlying OS can't seem to. I tried completely uninstalling the VM software, but this had no effect on my connection issues.
