ok, let's see if this is a WB225 NIC (AR9485 + AR30xx BT) https://techinfodepot.shoutwiki.com/wiki/Atheros_AR5B225 I added btcoex support a while back but didn't enable it by default. You need to add hint.ath.0.btcoex_profile="wb225" to /boot/loader.conf and reboot. It needs to be there before probe/attach so the btcoex code can see it. Then check dmesg for 'Enabling WB225 BTCOEX'. the AR9485 has an external antenna switch IC that switches between bluetooth and wifi, and if it's not all configured correctly you'll end up with no receive. :-)
I see 'Enabling WB225 BTCOEX' in dmesg but `ifconfig wlan0 scan` and `ifconfig wlan0 list scan` produce empty output Can I debug this error ? `ar9300_hw_attach: ar9300_eeprom_attach returned 0`
