I haven't seen any of those problems with my Cisco 350 card, but that's 
because I run FreeBSD 4.6, not Windows NT 5.0, on my laptop. :-)  I can 
even do monitor-mode sniffing....  (I haven't checked whether, in 
promiscuous mode but not monitor mode, I can see outgoing traffic, but 
given the way BPF works, I have no reason to expect that I *won't* see 
outgoing traffic, in addition to the incoming and third-party traffic I 
saw.)

Linux should also work better than Windows in that case.  People doing 
wireless sniffing with WinPcap-based applications on Windows should be 
prepared for disappointment....
