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
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?
