I don't use the 'wmiconfig tool'; I have two desktop application
templates which toggle an desktop icon between UP and DOWN and in which
a sequence of commands are fired up to bring Wifi UP or DOWN; this works
*very* reliable in the sense of bringing Wifi UP or DOWN, associating,
getting IP via DHCP and so on;

I can't comment on this because I don't use suspend mode; maybe one
could measure the drain of power with a special USB cable while the
battery is pulled out...
