ifconfig: interface wlan0 does not exist on ThinkPad X1 Carbon

I've just installed FreeBSD 13.1-RELEASE on a ThinkPad X1 Carbon and am trying to get Wi-Fi working and am missing something...

Following

docs.freebsd.org

Chapter 34. Advanced Networking

Advanced networking in FreeBSD: basics of gateways and routes, CARP, how to configure multiple VLANs on FreeBSD, etc
docs.freebsd.org docs.freebsd.org

I have

pciconf -lv | grep -B 3 network

-> iwn0

sysctl net.wlan.devices

->net.wlan.devices: iwn0

/etc/rc.conf contains:-
Code: 
wlans_iwn0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

Do I need to add something to /boot/loader.conf to support this device (Centrino Advanced-N 6205 [Taylor Peak])?

dmesg contains:

Code: 
iwn0: <Intel Centrino Advanced-N 6205> mem 0xf0c00000-0xf0c01fff irq 17 at device 0.0 on pci2
which suggests the device is recognised at bootup.
 
After running ifconfig wlan0 up scan I get:

Code: 
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    ether 84:3a:4b:d0:83:34
    groups: wlan
    ssid "" channel 1 (2412 MHz 11b) bssid 84:3a:4b:d0:83:34
    regdomain FCC country US authmode OPEN privacy OFF txpower 30
    scanvalid 60 wme
    parent interface: iwn0
    media: IEEE 802.11 Wireless Ethernet autoselect mode 11b <monitor>
    status: running
    nd6 options=29<PERFORMNUD,IFDISABLED,AUTO_LINKLOCAL>

so I guess I must have enabled it somehow... No additions to /boot/loader.conf and no reboot.
 
Code: 
You also need to select a firmware for your device.
The firmware isn't included in the GENERIC kernel, only the driver itself. Have a look at kldstat, perhaps it's auto-loaded.
