You have to create the WLAN interface from the actual wlan
device:

# ifconfig wlan0 create wlandev rgephy0

Unfortunately the Handbook is not as clear on the WLAN setup as
it could be.  It took me a few hours to realize iwn0 wasn't
meant to show up in ifconfig's output.

After the drivers have attached you can list the available WLAN
devices using the command "sysctl net.wlan.devices":

# sysctl net.wlan.devices
net.wlan.devices: iwn0

You then have to create the actual WLAN interface from it:

# ifconfig wlan0 create wlandev iwn0
# ifconfig wlan0 up

Now run wpa_supplicant to associate it with an access point:

# wpa_supplicant -B -c /etc/wpa_supplicant.conf -i wlan0 -P /var/run/wpa_supplicant/wlan0.pid

Then configure its IP address either statically:

# ifconfig wlan0 inet 192.168.2.124/24

or dynamically:

# dhclient wlan0


ifconfig_wlan0="DHCP"
wlans_iwn0="wlan0"
