This is almost certainly either a WinPcap issue or a driver issue. Try
running WinDump:
http://netgroup-serv.polito.it/windump/
and see if you have similar problems.
If so, send mail to
windump@xxxxxxxxxxxxxxxxxxxxxxx
about it.
Note that WinPcap might not put the card, or its driver, into a "raw
mode" where you see raw 802.11 packets; unless it does, you're unlikely
to see beacon packets or any 802.11 packets other than data packets.
(The latest 2.4[.x] Linux kernel has, I think, a driver for Cisco
Aironet cards that allow you to run a command to put the card into that
sort of "raw mode", and Doug Ambrisko has, as I remember, a version of
the FreeBSD Aironet driver that lets you do that, but I don't know what
facilities there are for doing that on NT, regardless of the wireless
card you have.)
Note also that only the current CVS version of libpcap, and the 0.7
betas of libpcap, support raw 802.11, so WinPcap is unlikely to support
it until a release comes out that's based on 0.7 (the next release will
be based on 0.6.2.)
That shouldn't affect data packets, though, although it will probably
mean you won't see anything other than data packets.
