Hi,
a/n is AC band.
you can check on wlc interface (Wireless --> Radio) and see that channels are from 44 to 56

look at the clients connected: if they are a/n ... that is AC

here is a snapshot2.png of a client laptop
I guess that it must be AC if it connects to 5GHz

Hi,
partial correction:

AC can only go on 5GHz, while "n" standard can go (only on latest devices) at both 2,4 GHz and 5 GHz.
In your picture it is reported a 20MHz band which corresponds to 150Mbps max speed: so i'd say it is a standard "n" connection in the 5 GHz channel.

For your laptop, you can see if it supports AC by checking the following command:
netsh wlan show drivers
