Failed to initialise WiFi module

@CreateAndCarveCNC please reconfigure your terminal emulator to recognise <LF> alone as a line terminator, to make the output easier to read.

Which version of WiFi firmware were you trying to install? Your main board firmware version is old (3.3) and the version of WiFi firmware that you are trying to install may be too recent for it.

@dc42 Thank you for getting back to me. I haven't changed anything just tried to reconnect it again so it did used to work.

Please can I have the instructions on how to get this information for you to check?

Many thanks

Can you try and configure it to work in access point mode? This will have the Duet create a wifi network that you then connect to. This will help determine if the module is having the problem or something else.

There isn't an easy way to check what version a particular WiFi file is; but you could compare the exact size of the DuetWiFiServer.bin file on your SD card with the size of the same file in the RRF 3.3 release at https://github.com/Duet3D/RepRapFirmware/releases/tag/3.3.

@dc42 this is the one on the SD card DuetWiFiServer.bin 255 KB Jun 16, 2021

@Phaedrux Unfortunately this hasn't worked, it is still showing the same message

[Phaedrux]

Is this a new board, or one that worked previously?
When and where did you purchase it?

[CreateAndCarveCNC]

@Phaedrux I purchased back in December last year with my CNC machine from Ooznest.
Yeah, It has been working perfectly fine for all this time, with almost daily use, up until the end of last week

[Phaedrux]

Can you also send the following commands via usb terminal and report what they return?

@CreateAndCarveCNC looks like your wifi module has died to me

[CreateAndCarveCNC]

@jay_s_uk Do you think it is unsalvageable?

[jay_s_uk]

@CreateAndCarveCNC I would guess it will need the wifi module changing. It may be possible with a soldering iron. I usually do it with a hotair station

[CreateAndCarveCNC]

@jay_s_uk ok, thank you.

Would you say that would solve the problem or would I need a new one all together?

[jay_s_uk]

@CreateAndCarveCNC i would say that will probably solve the problem, or at least its a good place to start

[CreateAndCarveCNC]

@jay_s_uk ok thank you, can you suggest the best place to purchase from please?

[jay_s_uk]

@CreateAndCarveCNC which version of the Duet 2 do you have? The older ones have an ESP-12S. When I replaced them, I went for an ESP-07S so I could use an external aerial

[CreateAndCarveCNC]

@jay_s_uk The one I have is Duet2 Main W51596. It has an external aerial.

[jay_s_uk]

@CreateAndCarveCNC then you would need a ESP-WROOM-02U

Thank you, can you recommend a reliable place to purchase at all please?
