You Rock Server doesn’t need to be on WiFI just plug it in to your router and let all your endpoints be on WiFi. Most routers have 4/5 ports, hide the NUC somewhere close to it, or get a switch, they cost pennies.
To get WiFi working you’ll have to try other Linux distributions such as Ubuntu, or Windows, or a Hackintosh if you want to use MacOS.
If you install Ubuntu server, you’ll need to enable Wifi by modifying a cfg file I believe.
