I have tried in many ways:
1) Wireless APs →Bulk Configuration → APs Default Settings → selected my AP type: here I switch on the radio 1 but I can't select Radio Mode
2) Wireless APs →Bulk Configuration → APs multi edit settings → select desired APS: here I turn on Admin mode above Radio 1 , but I can't select radio mode and after a Save the Radio 1 is always off
3) Wireless APs → APs → All → select a single AP from list → Radio 1: here I turn on Admin mode but I can't choose Radio mode, and after a Save the admin mode come back to off
4) Wireless APs →APs default settings → Common configuraton: I have turn on radio 1 and radio 2 next to my WLAN name, but I have no results.

For bulk config you must first set your country every time, did you do that?
The same applies for single AP, it must know the country to know the available channels.
You will also need a VNS defining and adding to the AP radio(s) and if the AP has an external antenna, this must be defined.
