I'm not exactly a specialist for wireless, but as far as I remember my lectures the 802.11 has additional MAC fields for the wireless source/destination. Stations always send to the AP, the AP retransmits it to the station. IIRC WPA/WPA2 even has some protection against stations forging the AP MAC with the shared group key, but I don't remember any details. Bernhard
