Your problem is the library. Neither WinPcap nor LibPcap seem to be capable of reassembling the radio transmissions sent out of a wireless card. It can only reassemble packets sent TO a wireless card on that machine (the host running ethereal).
Your best bet is to install linux and download AirSnort.

What operating system is the PC running Ethereal running?
If it's Windows, this is probably a WinPcap or driver problem, and you
should contact the WinPcap developers to find out whether anything can
be done. (It's probably a driver problem.)
If it's Linux or BSD, it's probably a driver problem, and you should
report it as a problem in the Linux distribution or BSD version you're
using.
