If you are using the "stock" FreeBSD "an" driver, that would account for the problem(s) you're seeing. The driver needs some patches in order to use what is called "monitor mode" (where raw 802.11 frames can be made available via bpf). (If you've applied the patches, you need to use "ancontrol -M" to set the monitor mode.) Doug Ambrisko's patches to do this may be found at http://www.ambrisko.com/doug/an/. However, they are based on a -STABLE that is a few weeks old, and some of the patches may not apply cleanly. I can generate a patchset (based on today's -STABLE), if that would be useful; I derived one for (yesterday's) -CURRENT, which is at http://www.catwhisker.org/~david/FreeBSD/an-current.patch. (That's the non-KSE version of -CURRENT, BTW.) Cheers, david -- David H.
