Hi,
got a new Duet 2 Wifi which I wanted to set up.
However, it returns "No WiFi interface available" on M587.
I also tried:
M115: "FIRMWARE_NAME: RepRapFirmware for Duet 2 WiFi/Ethernet FIRMWARE_VERSION: 2.05.1 ELECTRONICS: Duet Ethernet 1.02 or later FIRMWARE_DATE: 2020-02-09b1"
And M122 which does not return anything and requires a reconnect to the Duet.

Reinstalling the Firmware of the Duet and the WiFi Module did not change the behavior.

Looking at the board it seems as if a connection on the WiFi Module is not properly soldered, but I have no experience with that:

I'm thankful for any Input!
