NB: SOLVED. Vaio laptops have a switch on the front right that turns wireless on and off.
My Dad's in a different town from me, he's told me his wireless isn't working. I logged in using logmein and it looks ok generally, though wireless it turned off in the system tray.
When I click on the "wireless LAN" slider or try to slide it it says "Turn the Wireless Switch on the VAIO to ON".
Does anyone know what this "wireless switch" is? I've had Dad look all over the laptop and he can't see anything, just buttons with web, assist, and something else I can't remember but didn't sound relevant.
