I have tried it with the switch on and off also the F2 option. Today it worked fine for 10 minutes then the computer froze not even able to turn it off! After start up a small box simply says "adapter problem driver not installed".
I have the toshiba recovery and applications/drivers dvd satellite disc that came with it and it has the facility to run either full recovery (Not without losing everything) I suspect? or just re-install driver etc but the trouble is there is an awful lot on there and which driver is which albeit 3 of them do refer to wifi
Sorry to be a pain
