The Radxa Dragon Q6A on Armbian may lose Wi‑Fi after a kernel upgrade because the AIC8800 Wi‑Fi/BT module's DKMS driver fails to rebuild automatically; users report manually running sudo dpkg-reconfigure aic8800-usb-dkms can restore Wi‑Fi until the next kernel update.
After it was done I just did a quick reboot and Wireless and Bluetooth were back.
