The following are excerpts from Ethereal's FAQ

Q 5.37: I'm trying to capture 802.11 traffic on Windows; why am I not seeing any packets?
A: At least some 802.11 card drivers on Windows appear not to see any packets if they're running in promiscuous mode. Try turning promiscuous mode off; you'll only be able to see packets sent by and received by your machine, not third-party traffic, and it'll look like Ethernet traffic and won't include any management or control frames, but that's a limitation of the card drivers.
Q 5.38: I'm trying to capture 802.11 traffic on Windows; why am I seeing packets received by the machine on which I'm capturing traffic, but not packets sent by that machine?
A: This appears to be another problem with promiscuous mode; try turning it off.
