Well today a little progress, as the SD card is now visible , might have been an issue with 'debris' within the slot?
I managed to get all the zip files, but we need this 'bin' file??
Make sure you have an 'iap4e.bin' (for Duet 2 WiFi/Ethernet)
I had a look in the .zip file and the iap4e is not present within the zip and it is NOT listed within the assets of the version 3.5
although according to below as we are running version 2.04 (dated 2019-11-01) then the iap4e is maybe 'not suitable'?
########
The version 3.01 and later binaries are too large to be installed by the IAP program supported by version 1.x and 2.x firmware. Therefore you cannot upgrade directly from version 1.x or 2.x firmware to 3.01 or later firmware.
#########
i do get an error message from the Duet saying that "iap4e.bin" not found which suggest that it is attempting to re-programme
In a fit of desperation did a 'Google search' and then Downloaded from an 'old location'
this might be useful for others?

results from latest effort, so it would appear to NOT have updated?

It would appear that we have WiFi working but still not connecting using the DWC, although it 'suggests' that the firmware has been updated?
