What works now?  The Wired network connection or the WiFi one?

We're simulating a whole computer within your desktop system.  Each computer that exists on any network has a network device connected to that network wire.  That network device, by definition is supposed to have a unique MAC address which allows the network to send packets to that device and to receive packets from that device.

I'm not sure exactly what you mean by 'need at least one ip host connexion alive'.  Are you saying that you need to be connected to a network?

If you are asking 'why' details specifically about WiFi functionality, you are beyond the scope of my support.  I don't run simh simulators on WiFi networks due to the limitations of WiFi supporting a single MAC address per WiFi connection, and my needs to test the breadth of protocol functional for DEC systems.

I've tried to walk you through getting things working on a wired network connection.  Once you are successful there, you are welcome to explore whether what you are trying to do can also be made to work on a WiFi connection.  There is some discussion about this in the simh FAQ (http://simh.trailing-edge.com/pdf/simh_faq.pdf).
