Manage quota by SSID?

[mc0e]

I have three SSIDs - 2.4GHz, 5Ghz and guest.

I'd like to assign different quota policies to devices that are not using known MAC addresses, based on which SSID they log in through.

I can assign quota by IP. Is there a way that I can use different IP ranges for each WiFi SSID?

I don't think so

Easy solution is to get two routers

No doubt you would be able to do something via command line if you want to go in that direction.
