Windows 7: Wifi Network Adapter not detected by Windows & after BSOD

Wifi Network Adapter not detected by Windows & after BSOD

Hi

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.

Thanks

Follow this link and scroll down and refine your search results for Windows 7 64bit and then choose network list and eliminate each driver until you find the correct one that works. I apologize I cannot tell you exactly which one.

Ok, I got the solution.

The trick was to go to Control Panel > Device Manager > Network Adapters and the Right-click and select "Scan for Hardware Changes". Windows scanned the entire hardware and signalled to itself that there is a wifi adapter attached.

Somehow the BSOD had made some changes in the system so that it appeared that there was no wifi adapter installed.

Thanks Grego86 for your help.
