Please help me with the exact same problem with the exact same board, distro, and wifi card. I am very inexperienced with Linux and am having the same problem. Tried installing the firmware manually, tried running apt install armbian-full-firmware, and it ran through the whole rigamarole, but I'm still having trouble. Wifi module isn't in armbian-config, but it is in device list, wifi options are in the GUI, but doesn't find any networks.
usr/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm DOES exist but I don't know how to delete it.
Dmesg results in image
