On my Gateway laptop that has built in WIFI and was working just fine I noticed that it can be turned on or off. with a button on the side of the computer that has, wireless on or off. It never did turn the wireless off. So I went to the Windows mobility center and turned it off there, which it did. But now it will not turn it on again. the button is grayed out. Thank God my wired connection works just fine. But sometimes I might want to use the computer in a different room. Then it would come in handy. Any ideas? anybody.
