If you know the MAC address that are whitelisted you can change it

in *nix

and bring it back up

as for windows/mac i have no clue.

There are ways you can find out the MAC address, one is from a program called Cain and Able, you will need the Airpcap drivers for it though, they are like Winpcap but for wireless cards. Airsnort-NG might tell you the mac address, or if you have the balls just go look at one PC that is whitelisted and copy down the mac address which is USUALLY listed on the wifi device.
