Intel Pro Wireless 2915 adapter refuses to search the net. It looks like "dead device".
Is there anyone who knows what is that?
(sorry my english, I'm not an english-spoken person)

If you go to Device Manager (Right click My Computer > Properties > Hardware > Device Manager) is there a yellow exclaimation mark?
