Show actually used ssid of known-beacons?

[coolrboo]

Hola, the hostapd output only shows that a mac connected to mana-ap but is there a way to see the ssid the client used to connect?
It seems that airodump does not sniff reliably.
The goal is just to enumerate all items in the PNL.

How does the "beaconing" work anyway? Client hops fastly through all the channels and the AP beacons n times per second?
So, eaphammer's hostapd has a predefined channel??
