or running from an router assigned internal IP address? If she's on router, and it's not part of the modem, but there's a separate modem, hook to that, taking the router out of the loop. You could post the ipconfig readout and maybe that will help diagnose any problems.
I'm completely stumped on this issue, and I can't find any help specific to this on the internet.
My girlfriend's computer can't browse the internet. It HAS internet, it just can't use it. The only time it ever works, is after a restart. Then after a few hours of usage, it will stop working. Naturally, restarting the computer every few hours is an undesirable solution. It is a very minimalist computer, with very few programs outside of iTunes, Comodo, and Avast, and Chrome has no extensions.
I've tried disabling the antivirus and firewall, ipconfig/release and renew, double checking to make sure no proxy server had magically appeared, and reinstalling the appropriate driver in device manager. I've opened task manager and made sure there's nothing suspicious or unnecessary running in the background.
The weird thing is, she still has a valid ip. It's a normal 192 ip that you'd expect from a router, and she can successfully ping out to google. My computer is connected to the same network, and I'm browsing fine, and she's able to access files on my computer, so I can't wrap my head around what could possibly be wrong in this situation.
Any suggestions?
