Here the output of the command show ap association client-mac <device Mac >:
The phy column shows client's operational capabilities for current association
Flags: A: Active, B: Band Steerable, H: Hotspot(802.11u) client, K: 802.11K client, R: 802.11R client, W: WMM client, w: 802.11w client
PHY Details: HT : High throughput; 20: 20MHz; 40: 40MHz
VHT : Very High throughput; 80: 80MHz; 160: 160MHz; 80p80: 80MHz + 80MHz

The APs it's not very closed, but the strange thing is that the client is always associeted on the same AP, never with the others.
