Strange message Air/MacOS

[Jean-Marie]

Thank you for reply.

Downloads from configurator are ok with.png ,

Roon i've tried but can't work it out. Air x roon needs Devialet on my network and i've entered ssid & pword into configurator and updated D Premier but how do I know the D Premier is connected?

I've taken 14 day trial of roon , problem is inside settings > audio > networked , i don't have any device listed to enable. Mac is showing as the core and I can run Tidal via roon through the mac. All other settings like firewall and allowing app' to run are ok ... i read this on another thread. I've unistalled AIR too. I'm running the latest firmware for D Premier 10.1.0 i think it is.

I'm tempted to make a bold request for assistance from nearest Devialet dealer 20 miles away. I'm sure this must be simple to modestly capable individuals.

You should be able to check if the D was allocated a IP address by cycling through the screens on the D after a long press on the right button of the remote. 
One of the screen shall be labeled WiFi and if you have an IP address, a mask and a router address it means you are connected on your network. 
If if it says no IP address, then your first step is to properly get on you WiFi. 
Only then Roon will be able to see it and you need to enable it in Roon, going into settings and then audio. 

Cheers,
