XLR8Yourmac kept on investigating about AirDrop Compatible Wi-Fi cards.
Broadcom models BCM94322MC, BCM94322HM8L, Atheros AR5BXB112, AR5BXB92, AR5BHB92, AR5B93 are compatible
Broadcom models BCM94321MC, BCM94312MCG, BCM94312MCAG, BCM94311MCG do not support AirDrop
The list will probably get bigger, and we hope to see as may compatible cards as possible.
