hello wifi list, I want to test out 802.11n in hostap mode on FreeBSD, my aim is to provide the developers with as much feedback as I can.. is there a wiki somewhere, that says how to put up a ath device in hostap and specifically use 802.11n (2.4 band) I want to know things like, what lines specifically do I put in my /etc/rc.conf so that it starts up on boot. What lines do I use in rc.conf to get a client to connect via 802.11n (in FreeBSD HEAD) I know ath has a manpage, but it doesn't specify any 802.11n stuff, even if you build -HEAD I have read this page, https://wiki.freebsd.org/dev/ath%284%29/80211n and built a kernel with the correct options.. as you can see from the output below, using a command similar to: # ifconfig wlan0 channel 6:ht/40 i am new to the whole 802.11n thing, if I have 2.4gz 11n stuff that means it is ht/20 only correct? I just need a bit of a primer on this whole thing, and that is why I am asking about a wiki page... here is some random output from commands I typed that should give some more background as to the hardware I have. root@Border:~ # dmesg | more Copyright (c) 1992-2013 The FreeBSD Project.
