With FreeBSD 10.3 my Atheros card worked fine and showed up as /dev/ath0. Now with FreeBSD 11 this is no longer the case, though the module is loaded and it seems the system recognizes the card:

root@igloo:~ # sysctl net.wlan.devices
net.wlan.devices: ath0

Still, ath0 cannot be used:

root@igloo:~ # ifconfig wlan0 create wlandevice ath0
ifconfig: must specify a parent device (wlandev) when creating

What must I do to use the card?

The error message says you need to use wlandev rather than wlandevice.

Try:

ifconfig wlan0 create wlandev ath0

More information and examples can be found here in the ath(4) manpage.

To configure the network , edit your /etc/rc.conf by adding the following line ( to configure the network on startup):

wlans_ath0="wlan0"
ifconfig_wlan0="WPA SYNCDHCP"

Create a wlan interface:

ifconfig wlan0 create wlandev ath0

Scan for access points:

ifconfig wlan0 up scan

Create a /etc/wpa_supplicant.conf configuration file with the following contents:

network={
ssid="your_ssid"
psk="your_password"
}

Connect:

To connect you need to restart the network service:

service netif restart

After restarting the network service, the wifi should work.

Also you can connect through wpa_supplicant:

wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf

Just to add my experience to this thread. I am convering an old Asus P5G41T-MLX machine to run FreeBSD 11.1 Initally it would not find the Atheros AR8131-BL1A device. Updating the BIOS resolved the problem
