I am not 100% sure if this is responsible but almost right after the update I have trouble connecting to routers. There is one router I have the wpa2 key for but when I fill this out it won't connect. Using the button on the router to connect also doesn't work. The router shows activity whenever the pc is trying to connect. There is also a WiFi from the neighbors that is open. I can connect to that one some of the time, but most of the time there is no internet connection. Also sometimes when connecting it asks me for a key, although the connection is open. Other computers can connect without problems.
Connecting the pc to the router with a lan cable works though.
I tried fiddling with ipconfig, and using static ip's. Deactivated the adapers and switched them on again. Deleted wireless networks and updated drivers.
The OS is Windows 7 64bit. The pc is a Dell XPS.
Thanks for your help.
