The wlan system will auto-select 11n (wide channels, MIMO) as supported
by interface and network. See "ht" flag in ifconfig(8).

Did you try adding "mode 11a" to select 5GHz band? (This might be
out-of-date, as my WiFi stuff is all on 11) (currently I'm also
using 2.4GHz only, for compatibility with some devices and the fact
that I have quite some trouble running 2.4GHz and 5GHz from the same
interface at the same time).

Christoph
