Duet 3 Mini 5+ Wifi not connecting

selva_tvi

Hi all,

We have two machines installed with Duet 3 Mini 5+. We used to get frequent issues with wifi.

It disconnects automatically. When we try to reconnect wifi with the below codes.

'M552 S0 ; disable network module
G4 S5 ; wait 5 seconds
M552 S1 ; enable network module'

Sometimes it works, sometimes it wont work. Next day when we start the machine, it connects automatically.

Please find the video attached.

@selva_tvi post an M122 output once its connected

jay_s_uk

@selva_tvi you could try updating to 3.4.4 and the latest WiFi server 1.27 and see if that makes a difference.
Can you also run M587 and see if there are any other WiFi networks reported other than yours?

Phaedrux

Where is the Duet mounted in the machine?

Please update the firmware to 3.4.4/1.27 as Jay suggests.

Can you post your config.g?

selva_tvi

@Phaedrux please find the Wifi and board location in the image.

Phaedrux

Were you able to update the firmware?

selva_tvi

@Phaedrux @jay_s_uk We updated the Duet firmware and Wifi firmware also.

After updating the Wifi Firmware, the following message is coming.
WiFi reported error: no known networks found
The WiFi module is idle

But in another machine, the Wifi is working properly (same configuration)

Kindly support. Client is in a urgent print.

Please find the M122 report after updating the firmware.
