So I’ve poked into armbian-config application and attempted to install an extra 2.0ghz module and did “firmware update”, and in the end the wlan0 adapter got killed and all wifi modules were unloaded.
I am actually completely in the dark about how to restore wifi short of reflashing the SD card image, which I don’t want - i already had a lot of stuff recompiled and installed.
Any possible tips about restoring the wifi module?
