@dc42 said in Strange Wifi Problems:

If the attempt to reinstall the WiFi firmware eventually resulted in message "Failed to connect at any baud rate", that is enough evidence. It should normally connect at the first baud rate that it tries.

PS - I forgot to mention: make sure the Duet has adequate power when trying to upload WiFi firmware. In particular, a USB port on a laptop may not provide sufficient power if a panelDue is connected. It's best to use VIN power.

U2 is the 3.3V regulator. The only known reason why it fails is that either the +3.3v rail or the +5v rail was shorted to a high voltage.

Wiring endstop switches incorrectly will short +3.3v to ground, but that doesn't normally cause the regulator to fail because its short circuit protection kicks in.

@makerdise Can you confirm what happens when you program it using fall back procedure 3 without an SD card inserted.
