Troubles to connect in 5G as a client


I have a lot of trouble to connect to a 5G wifi as a client.
What worked so far:

  • 2.4G client -> 2.4G AP
  • 2.4G client -> 5G AP
But impossible to connect as a client in 5G. I see the network I want to connect to but when it is not able to create the connection and after some time is is disconnected.

Edit: I solved it, using the advanced configuration. It was not possible from the basic UI.

which model are you using? AR750? The basic UI should work.
