"Wireless adapters may present problems, because they are not properly 
supported by the Windows Kernel: some of them are not detected, other 
don't support promiscuous mode. In the best case, WinPcap is able to see 
an Ethernet emulation and not the real transiting packets: this means 
that the 802.11 frames are transformed into fake Ethernet frames before 
being captured, and that control frames are not received."

If you want to capture the 802.11 MAC header, try running Linux or 
recent versions of the BSDs:
