@dc42 many thanks for your fast answer ! Will do that.

Thanks a lot !

Hello,

I'm Patrick from France. I've been using Duet3D for 4 years now and have never had any issues until 2 months ago, when I started receiving the following message and couldn't connect to my WiFi:

"WiFi module disabled - start timed out"

Suddenly, the board started working again. Sometimes it was impossible to connect to WiFi, but it would work occasionally.

However, yesterday, the same problem occurred, and this time I couldn't solve it.

Based on many forum discussions, it seems my WiFi module is fried.

I tried flashing different firmwares—didn't work.
I erased the board and reinstalled using Bossa—still didn't work.
I even tried a different SD card—no success.

I've run an m122 with the result below (my board was connected to my laptop with YAT, because impossible to use DWC of course)

My board came from DOLD Mechatronik in germany, and Sarah from duet3d told the seller that I have to post so it's done mates !

Thanks for your help !
