Active DHCP Leases > only LAN clients

Hello,
I have configured multiple VLANs, and a dumb AP.
The wifi interface provides 2 networks: LAN and IoT.

In AP's Luci webUI I can see multiple "Associated Station", however "Active DHCP Leases" in router's Luci webUI only shows LAN clients.

Can you please advise what is missing to see all clients connected to wifi?

The "Active DHCP Leases" page will only show DHCP clients, it will not show clients connected to wifi, unless they make a DHCP request.

Anyway, how dumb is your dumb AP? It does not have a DHCP server, right?
