Sound switch not recognizing my prime 4

I’m having trouble with my Sound Switch not recognizing my Prime 4. In my set up it only shows Engine Prime and stand alone options but not Prime 4

Had this issue as well. I first replaced the network cable and second i downgraded from 1.6.0 Beta to 1.5.2 - now the Prime 4 shows up with a blue circle in “Performance Mode”. On MacOS you should disable WiFi for sure but i also did so on Windows.
