Wifi module seems to be dead

[SergioBA]

Since this morning my wifi module seems to be dead.
I´ve tried flashing firmware again, setting manually wifi parameters, etc, but nothing seems to work.
I´m having the same issues as the user in this thread: https://forum.duet3d.com/topic/3332/cant-get-the-wifi-to-work
I´ve tried everything you suggested in that thread, unsucessfully.

Any ideas?

Beyond that, the wifi conection was allways unstable, making uploading files a pain, while my second duet which I bought a month ago works perfectly with the same configuration, same printer and network.
Also, I'm having issues with missing steps in the X axis, happening at the same height in the same file, while the exact same file prints perfectly in my second printer with duet. It not a hardware issue, I've checked that a hundred times.

Thanks in advance

Does uploading firmware to the WiFi module using M997 S1 succeed, or not?

@dc42 Hi. Thank tou for your answer.
No, it doesn't work

I think I might need a replacement. I've tried everything but the wifi never turns on

[dc42]

If uploading WiFi firmware using M997 S1 fails with "Could not connect at any speed" then the WiFi module should be replaced. If it fails with a different message, please tell us what the message is.

@dc42 that's the message I got
How should I proceed?
