I used windows 8 supported Wifi adaptor by win2012.
It worked fine.
But , recently suddenly device is not recognized by OS.
If I did ipconfig, it says media is not connected.
But I can see My SSID and can connect to my SSID using that adaptor.
I reinstalled Wifi driver and restsart Wifi service but ,the situation is same.
By device manager there is no problem and Wifi adaptor is recognized.
What should I do ?
