RT-AX92U dead WiFi

[Ikke]

My RT-AX92U's Wi-Fi stopped working after a firmware update. The Wi-Fi light doesn't turn on.
The MAC address isn't displayed in the management screen either.
I tried recovery mode, but it didn't change anything.
The LAN MAC address displayed is also different from the one on the device's label.
A dialog box appears asking me to set a Country Code, but I don't know what to enter.
Is there anything I can try to get the Wi-Fi working again?
