Traffic cap in mb outside captive portal

Hi there

I’m using MAX BR1 Mini (HW1) on some busses… my customer wants to have 2 wifi SSID running:

  • the public one, open, with CP and social login for people using the bus
  • a private one, protected by WPA2 password, for bus’ drivers

now, I’m facing a request coming from the customer… He needs that the private wifi has some bandwidth cap too… IOW, a driver should have a quota check too.

I see this is non available and, due to firmware limit, I can’t have a second CP

is there any way to achieve such a thing?
