No wlan0 interface created for an Intel(R) Centrino(R) Wireless-N 2200 BGN device

[Alexandr Krivulya]

Hi!
You need to load firmware in your /boot/loader.conf

if_iwn_load="YES"
iwn2000fw_load="YES"
iwn2030fw_load="YES"

not sure wich firmware is correct, see man 4 iwn.

You need also corresponding interface settings in /etc/rc.conf
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA DHCP"
