The Fn + F2 combination on my Dell Latitude turns the wireless card (or "radio") on and off. Other than the fact that I have no connectivity to my WAP each other time I press it, however, I can find no evidence that the radio is off. There's an "Wireless device off" check box on the Advanced tab of the Wireless Device properties dialog, but this check box doesn't change when I press Fn + F2. Is there a place where I can see the "true" status of the wireless card (or "radio")? And, is this status unique to Dell or do other Windows laptops (HP, Sony...) have similar functionality?
