Console into the AP and reboot the AP.  

Post the entire boot-up process.

[Khalidhassan832]

I am far from the AP, will let you know once I can get the boot process.

 - Check ap-model , versus controller-model constraints with :

[Khalidhassan832]

I checked the software it is compatible with the AP model, any other suggestion ? 

[marce1000]

 - You will need the output from the complete boot process as Leo suggested,

Dear All,

     The problem was MIC expired on the 29th of August unlucky, I had disabled it and now everything is working fine.

Thank you all.
