which drivers do automatically switch off the radio of WLAN? thats just silly, we have to kick the programmers asses [6] my, althought externally pcmcia wlan card does work like a charm with the standard vista drivers.

it could likely be that you have to install a utility or driver from acer to get your special buttons to live (if they aren't BIOS controlled and windows known).
or maybe you have a bios option for the default behavior of your WLAN antenna?
