Hello folks.
I am here once again trying to figure out how to enable 802.11n in
HOSTAPD for the Atheros 9280 wireless chip on FreeBSD 11.
Although "ieee80211n" is not recognized by FreeBSD's HOSTAPD, If I am
not mistaken I was told that it would handle 802.11n tx/rx automatically
on supported interfaces, and based on
https://wiki.freebsd.org/dev/ath(4)/80211n mine appear to be supported.
Still, the antennas are transferring in G mode.
Do I need to build a custom kernel with "options ATH_ENABLE_11N"
enabled? Also, do I need to be on -HEAD for this to work? I have
downloaded 11-STABLE branch sources and "options ATH_ENABLE_11N" seems
to be enabled by default with GENERIC kernel, I could be wrong though.
Right now I am on FreeBSD 11-RELEASE p9.
$ sudo dmesg |grep ath
