Duet 2 Wifi: wifi no longer works

tahi

Hello everyone.

I need help with the wifi on my card that has stopped working.

The card is a Duet 2 Wifi rev 1.04c with integrated antenna purchased in January with the original 3.2 firmware on the card.
I used the config tool and the wifi connected correctly. I had access to the web interface and the printer responded correctly.

This morning the machine would not connect. The blue diode was not lit anymore.
After a few tests that did not give anything, I thought that the files on the SD card might be corrupted.
It turned out that the SD card was dead without me understanding why.

So I changed it and copied the backup from the previous card.
I launch the printer and... it still doesn't work.

So I redid the configuration with the config tool by putting the information of my wifi. Still the same. No wifi diode and of course no connection.

I connected my PC in USB and I did M115 followed by M122 which gave me that:

M115

Since wifi is noted as disabled I tried an "M552 S1" and got this message:

M552 S1
"Turn off the current WiFi mode before selecting a new one
ok"

I tried to redo the manipulations of the first connection tutorial but nothing works.

I tried to make a M558 S "*" and I got the following message:

M558 S"*"
"Error: M588: Failed to reset the WiFi module to factory settings: another SPI transfer is pending"

I tried all the manipulations I found in the different topics but nothing works.

I'm lost.
What can I do?

Try sending these network commands

M552 S-1
M552 S0
M552 S1
M997 S1
M588 S"*"
M587  M587 S"ABC" P"password"

droftarts

@tahi also try reflashing the WiFi firmware with M997 S1.

@Phaedrux said in Duet 2 Wifi: wifi no longer works:

M997 S1

@droftarts it's in there

Hello and thank you for your answers.

I tried the manipulations and here is the result:

M552 S-1
WiFi module stopped
ok
M552 S0
ok
M552 S1
Turn off the current WiFi mode before selecting a new one
ok
M997 S1

Trying to connect at 74880 baud:  failed
Trying to connect at 9600 baud:  failed
Error: Installation failed due to comm write error

I'm starting to wonder if the wifi module might be down.

Yes I think that may be the case.
