Monitor is broken on iwi on FreeBSD 7. I did report it during the 
7.0-BETA, but there was at least one more report in the meantime.

With exactly the same setup, I can use kismet with ural (ok), zyd (many 
broken packages), ral (ok), and ath (good, but see below). I do not 
receive a single package with iwi.

I did replace my iwi miniPCI device by an ath one, which is more 
reliable anyhow. (iwi, as all Intel cards, occasionally dies and cannot 
reload firmware because of too little dma memory. That was reported a 
few times, too.)

ath can monitor, even for longer periods of time, but if I do channel 
hopping in kismet, it often eventually stops receiving packages after a 
few minutes. Restarting kismet always fixes that. (I have had that with 
different ath cards.)

iwi monitoring did work on 6.2, but often the card would not do regular 
networking after that until reboot and the problem with the firmware 
mentioned above was already present, although it was much better than on 

For monitoring, you should either get a different card or try 6.X, 
6-STABLE, or maybe 8-CURRENT. (I have no experience with the latter.)
