Hi @GregW,
Thanks for letting me know that information and providing the diagram, it is helpful. I just want to confirm, if you plug in the LSX to the same switch that the Core is on, they still don’t appear?
If you manually set the KEFs to Network mode (using the KEF Control app) is there any change in behavior?
I also wonder if factory resetting the speakers will help, the LSX should have a “Reset” button on the back, if you press and hold this until they start flashing, does this trigger any change in behavior?
