I have a Toshiba Satellite that the wireless adapter seems to have disappeared. I did not replace the hard drive or make any software changes. To the best of my knowledge, it was there one minute and gone the next (it's my parent's computer so details are a little hard to come by). The Ethernet connection still works. I've tried downloading what Toshiba says is the current driver but that hasn't helped either. There is a button that turns the antenna on or off. When I press it, the light goes off for a moment and a graphic is displayed on the screen telling me that it's either on or off. There is a light on the edge of the laptop that is on when the antenna actually is on but it doesn't do anything right now. There is a a Fn+F8 to do the same thing, or at least that's what the keyboard says. When I hit the Fn key, all of the options are displayed across the top of the screen but it skips the F8 key. I'm stumped. Any suggestions?
