@Hiroaki Send M552 S-1, then M122, M552 S0, then M122, and M552 S1, then M122. This is what the response from my Duet 2 WiFi looks like (you can just copy the WiFi part at the end):

okIf you're not getting something similar, I'd guess that the WiFi module has failed. The usual reason for this is a power surge on the 3.3V line; the WiFi board and SD card are often the first to fail if this has happened, but can protect the main processor from failing.
It is possible that the WiFi module firmware has not flashed correctly. Try downloading a fresh DuetWiFiServer-1.23.bin from https://github.com/Duet3D/RepRapFirmware/releases/tag/2.05.1 and upload it to the 'sys' folder on the SD card, then send
M997 S1

Hello @Hiroaki... I have had this issue myself a few times. The advice here did solve it; but I had to do it a couple of times. Re-flashing the firmware more than once might be necessary. I also found that in BOSSA, using the setting "erase all" seemed to yield the best results. Good luck to you!

@droftarts Thank you. As it's getting late night, I will do it tomorrow.
By the way do you think it's possible to change the wifi module ? -
@beachtec Thank you. I will try tomorrow. It's 0:21AM ...

One question .
Upload Duetwifiserver-1.23.bin to the SYS not WWW folder?

One question .
Upload Duetwifiserver-1.23.bin to the SYS not WWW folder?Yes, firmware updates go in the 'sys' folder. The 'www' folder is for DWC components.

@droftarts ok Thank you.
-
DuetWiFiServer-1.23.bin
I think you'll need to rename the file and remove the
-1.23
part so that the final file name is just DuetWiFiServer.bin -
