Hi Vladimir,
red LED is consistantly on and green LED flashing at boot and afterwards flashing up from time to time, but rather rarely, Pi is connected directly to router. To check the IP I’m looking at my Routers UI. It would be there if it gets an IP. I did not try a scanner but I’m sure thats not it. Especially because I bought a micro HDMI to have a look at what happens:

This is just looping. However I’m not really getting what it tries to tell me here… Is it about the Duet Board? Would you please have a look at this?
Thanks in advance
Edit:
It also displays the following information, forgot to provide that earlier.
