Hi @attila,
It's still not working when trying to connect with Ethernet Standard. I'm also getting the error intermittently when connected in Ethernet Linux, very infrequent though.
The IP is obtained through DHCP, I have tried both manual and DHCP. I have also tried other external ethernet adapters on the host to see if the error was due to host to interface communication. Looking at the traffic with Wireshark the communication seems to be working. I see UDP packages where it seems that the ADP is announcing itself, and I can see TCP communication between the host and the ADP when trying to connect.
