My laptop suddenly switch off when i was playing my game. As soon as i switch it back on, the wireless function is gone. There is no light on the wireless thingy and in the network connections, control panel... there's only local area network.
The wireless is gone! what shall i do? please advise, thank you!
Have you tried holding down the Fn (function) key and pressing the Toggle Wireless button? On my keyboard the Toggle Wireless key is F2. You can tell by the little pictures below the respective "F" keys at the top of the keyboard.
If that doesn't work, what were you doing on your computer when it shut off? If it was intensive or if the power to your house went off as well, there might have been a surge/short. If your tell me what kind of laptop you have, I might be able to help you find out if you have a Toggle Wireless button.
