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.
