I have Windows 7 Ultimate x64 on a Dell Inspiron Laptop. I also have Ubuntu 11.10 as a dual boot option on this machine.
Recently I got a BSOD with the following error -
DRIVER POWER STATE FAILURE
Since then Windows does not recognize the Wifi network adapter. It is not there in the Device Manager at all.
It does not seem to be a hardware problem because when I boot using Ubuntu, the Wifi works without any problem.
Can anyone guide me how to solve this issue. Since the adapter is not being listed in the device manager, I don't know how to update or reinstall drivers.
