Enterasys Wireless Controller: enable to switch on radio 1 on aps

[Fima18]

I have to modify a preconfigured Enterasys Wireless Controller. Each aps have radio 1 disabled and I need to switch on it on N wireless channel.
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.

Some ideas...
Thanks!

Thanks Gareth Mitchell , the problem is know clear: after an upgrade the controller has lost the license (I don't know why), and after that I was unable to change the AP properties. Now I have restored the license and everything goes good.

Thank you for support!

Demo licence doesn't allow config of 5Ghz radio, it also limits channel choice on 2.4Ghz, you need to licence the product or you can put a temporary eval licence that will activate the features https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-Request-IdentiFi-Wireless-Eval-lice...

Thanks. In country list I can select only "Demo Country". I suspect that the controller has lost the link with licence but I'm not sure: in licence section I see "DEMO" but I have 50 Licensed APs. Can this be the reason?

It is set per AP, but you can do the change with bulk settings

Per AP in the first config tab:

Bulk (Multi-edit)

As the GUI above says, set this first.
