Hi, I'd check in /usr/src/sys/net80211/* that should be everything having to do with wifi, other than the drivers themselves which are in /usr/src/sys/dev/* and /usr/src/sys/arch/*. If you want a guide to help you with these get a book. If you know german I'd get the wireless lans book by joerg rech (heise verlag) it actually is quite good. I personally use access points of other OS's (probably most openwrt based). However I'm mostly cabled at home and seldomly switch an AP on these days, due to the density of living quarters in here. I also have access points that are openwrt that is modded to report association requests per mac address via radiotap to a daemon that is running on OpenBSD. If you're interested in that send me a private mail. I used to want to use these for triangulation problems but the clock counter on openwrt devices is not finely grained enough for results. AFAIK it's safe to assume that a radio signal through vacuum is less than the speed of light. Take 1/3 or 1/2. Either way it's a waste of time to try to triangulate unless consumer hardware becomes a lot faster and solid. Personally if someone is on my access point and authenticated and using the Internet there is going to be an arp entry like you hinted on. Or an ndp entry for IPv6. Without these... they only have access to the link itself. Best Regards, -pjp
