The hostapd is compiled without CONFIG_IEEE80211N=y. The new ath drivers under Freebsd 11-CURRENT are having 802.11n capabilities. I can compile the port with CONFIG_IEEE80211N=y option. No problems at all. Wouldn't it be better having that support compiled in base system? The (n) is supported at least under ath drivers and it's working fine so far. Thank you so far.
^Triage: to submitter: is this still a problem on recent versions of FreeBSD?
