disable 2.4 Ghz radio on lightweight AP

If you want to do this from the GUI, clcik on the Wireless | Access Points | Radios | all the way on the right is a blue triangle, click that next to the AP you want to disable the band and click configure.  There you will disable the radio.

I'm sorry leo, you are not following me...

I need to disable 1 out of 11 APs the 2,4GHz (b/g/n) because when trying to airplay to an apple tv I have many issues with bluetooth mouses (same frequency). So I need only 5GHz at this AP

I see.  Can you post the complete output to the command "show ap config general AP_NAME".

 

I have a strange feeling the AP you want to enable 802.11a/n is only single-radio or the wrong Regulatory Domain.  This is why you are getting the error message when you attempt to enable 802.11a/n

Ok.  Just as I have suspected.  The AP in question only has one (1) radio and it's only 802.11b.   You will never be able to enable 802.11a.
