How to limit wi-fi speed on unifi?

Question

WiFi

Available:
1. Gateway on Linux
2. Separately, a unifi controller in the form of a proxmox virtual machine.
3. About 3 dozen points of ubiquity.
How can you kill the speed per client? Not on a network, and on the client or it is impossible? The problem is that the channel is easily utilized

Answer 1

In Unifi Network, there is User Groups in the settings, you can set different user groups there.

Further simply you cling the client to any of the adjusted groups.
Edited.
I really didn’t use this thing, we manage with magic on the Linux gate (we have the same scheme as in your question). We use HTB + iptables on the gate to divide users into groups and assign different priorities to their traffic.
