Hi,
I have a Duet Ethernet board, I'm connect it to the PC with the USB only, I put the 2.02a firmware to the board in this manner:
(https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3)
I delete all lines of the network on the config.g file (M552 etc)
I connected to the board with RepetierHost and try to enable the network with M552 S1 P0.0.0.0 but I got this error all the time:
"M552: Bad or missing SSID"
I can't turn the Ethernet on, This is the M122 after I'm run M552 S0:

It's seems that that the board think it have Wifi Module instead of Ethernet Module.

I also copy to the SD/sys this files from the release of 2.02:
Duet2CombinedFirmware.bin
DuetMaestroFirmware.bin
DuetWiFiServer.bin
and this file from this release:
iap4e.bin

and tried to update with the M997 S0:1:2 command but the module still don't work/recognized.

It was worked before I tried to upgrade from 1.21 (If I remembered right), I first tried to upgrade from the web interface and when the the display show duplicated file/macro and I can't upgrade from the web interface anymore I tried the M997 method and after that the Erase etc.

This is what I get after M997 S0:

What can I do to enable/use the Ethernet Module?
