Controllerless Networks

hello,  when I hidden the SSID  MPSK  with MPSK groups and device registration, the new devices registered not join the network.

If the ssid is visible magically the devices connect,

devices are: Ipad mini (6th generation)  Ios 17.2

I can't see nothing no client mac address in clearpass and also in the wifi controller logs

have you already esperienced this?

Don't hide SSIDs.  Some devices, and specifically Apple devices, don't like hidden SSIDs when used in conjunction with DFS channels.  In general, hidden SSIDs just cause problems and complicate roaming.  Don't hide SSIDs.  There is zero benefit.
