Wifi module is not working

Gopi

I have updated my Duet 2 wifi firmware from 3.2 to 3.4.1 via DWC. But during the update process the wifi connection was lost. When I tried to connect it to YAT I could see that the firmware has been updated to 3.4.1. But when I tried to run M552 S0 it just returned ok. With M552 S1 it returned Turn off the current WiFi mode before selecting a new one.

I tried to reflash the duet with M997 S1 but it returned Error: M997: File 0:/firmware/DuetWiFiServer.bin not found.

Couldn't find a solution to resolve this problem. Hope the experts on this platform help me to find a solution. Thanks for your time in advance.

Please let me know if you need further information.

@gopi please send

M552 S0
M997 S1
M552 S1

That should reflash the WiFi firmware and get you back up and running

@jay_s_uk M552 S0

M997 S1
Error: M997: File 0:/firmware/DuetWiFiServer.bin not found

@gopi you'll need to place the latest wifi firmware version in the firmware folder on the SD card. it can be found here https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.1/DuetWiFiServer.bin
then repeat the above

The problem is partly resolved. Thanks to your help, wifi module is now connected. But I could not connect to access the DWC via IP address. It shows that the www files are missing. And I could not find these files in the internet. I have attached an image of my SD card. I am using e3D tool changer printer.

@gopi you should have a folder called www in the root of the sd card.
extract the contents of this zip file https://github.com/Duet3D/RepRapFirmware/releases/download/3.4.1/DuetWebControl-SD.zip into that folder

@jay_s_uk My module is connected and running. Thanks for the help.
