I have a tp-link wn422g usb wirless adapter. it worked very well when i bought it. 2 weeks ago, I reinstalled windows 7 32x to my desktop and when i plugged the adapter it worked untill the time comes when the computer suddenly powered off because of electric current problems. since then, the adapter didn't work. I used windows troubleshooter and it gave me that message: ''there might be a problem with the driver for the wireless network connection adapter.''. it appears in device manager list but it don't search for connections as if it is unplugged. i uninstall/reinstall the drivers many times but nothing changed..i'd appreciate your help..thanks
