Duet wifi not working after change wifi settings

he 'Diag' LED is constantly on. I tried erase board but I can not update board because BOSSA do not see the board.
Is that the only LED??

@bearer 3.3V, 5V and USB power are also on.

Could the reset button be stuck in, or something shorting the reset button? The Duet gets stuck in a boot loop, and the diag light is always on, if it's constantly resetting. It also won't get picked up on USB.
Do any chips on the Duet get hot, or do any of them look damaged/burnt?Ian

@droftarts The restart button is not stuck, I checked it with a multimeter. Nothing looks damaged or burned, but it seems to me that the Atmel chip heats up quite quickly.

Have you tried the following:
- Rebooting Windows;
- If the Duet is connected to your PC via a USB hub, powering the hub down (i.e. disconnect it from the PC and from the local PSU if it has one) and up again;
- Connecting the Duet to a different USB port;
- Trying a different USB cable;
- Checking in Windows Device Manager whether there is an "Unknown device" when the Duet is connected?
Sometimes Windows gets in a state whereby it ignores a particular USB port. USB hubs sometimes get in the same state.

@dc42 I've tried everything, different USB port, different USB cable and different PC PC. Nothing, even an unknown device, is displayed in the Device Manager on any PC.

That and the lack of the Bossa port when you use the Erase button or jumper does suggest that the processor has blown.

How is that even possible? I didn't do anything that could do that. I just deleted the saved wifi via YAT and set a new one. And after reconnecting to USB, it stopped working.

Hard to say without knowing the age and origin of the board, but transients and esd are always the biggest sharks. Depending on where you got it and what consumer protection is like it could be the vendors job to prove you damaged it (it is here at least), so could be worth looking into.

When you say "I tried erase board", can you confirm that you fitted the Erase jumper and powered up the board, pr pressed the Erase button for one second or longer when the board was powered up (form USB will do)?
How hot does the MCU chip get? It's normal for it to run slightly warm, but not hot.

@dc42 Yes, I tried to follow https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware.
As for the temperature of the chip and after a while it gets pretty hot (I have no way to measure the temperature)
