after I installed Ubuntu 12.04 on my laptop alongside with Windows 7 64bit, my network adapter started having problems. Now, using windows, I can not connect to a network neither wireless nor wired. I've tried troubleshooter and i got the message that the broadcom 802.11n network adapter has a problem and it can not be solved automatically. I also tried deactivate and activate controllers and the problem still exists.
Can anyone please provide some help?
