PC causing internet to crash?

[jollyframe835]

A brief overview. Wifi works perfectly on all my devices (phone, tablet etc), except my desktop Windows 7 PC. Connects and works for a few minutes, but then the connection drops, not just for the PC but the router loses connection to the internet. This only ever happens when using my PC. I've turned off UPnP, opened up the necessary ports and as I said, everything else works and doesn't cause a crash, only the PC. Any suggestions appreciated!

Have you tried updating the drivers for your network card? Look in Control Panel. Device Manager, Network Cards and try updating your wi-fi network adapter. Restart your PC for changes to take effect. Good luck. And if you have a reset button on your router hold it in for a few seconds (while switched on) and reset your router before anything else.
