Me again, i have now 5 working. The way i solve this was in the following way.

I downloaded the configuration from one of the working AP´s and i upload this to the not working AP.

I change the Ip from the Network configuration and the Radius Nas ID in Services, and it works.

But i still do not know where the problem is or what is missed. I want to send you the screenshoot from the one AP´s what is still not working so you maybe can tell me where the problem is and what is missed.

Thanks in advance.
