Hi Jo. This happens as when upgrading or reflashing the firmware the WiFi address is not written to the Nand. During restore. You can try downgrading 1st to see if that may solve the issue. If not then the data signal from the Wifi chip to the nand is damaged more than likely through a knock. More often than not though you have to replace the WiFi chip to recover the data signals and pair the WiFi for it to function again
