do you have the file, /etc/wpa_supplicant/wpa_supplicant-wlan0.conf, with this image: Debian 11.x (Bullseye) - Monthly Snapshot - 2023-10-07 ?
Or…
do you have the command, iwctl, with this image: Debian 12.x (Bookworm) - Monthly Snapshot - 2023-10-07 ?
And…
If you have iwctl as a command, can you use the commands to start WiFi?
