Hello, i need help with the following problem:
I have 2 ISP and i want to broadcast 2 wireless ssid's one for each provider. Any ideas on how to do that. I don't need load balancing the two isp's must work together.

The requirements are not well understood.
a. you have two isps
b. you have one MT router model?
c. you wish to have two wifi networks, (two SSIDs) with each being serviced by one ISP
(isp1- ssid1, isp2 -ssid-2)

What subnets do you have on the router, can we assume three subnets?
1- wired normal use subnet a
2- ssid-1 subnet b
3. ssid-2 subnet c

Diagrams would help

Hi, I've made a diagram of the problem.
Yes,I have two ISP, the Router model is RB1100ahx2, and i wish to have two separate ssid's on the access point one for each provider.
The AP's are Unifi AC-LR that support two ssid'd and vlan.
For the moment the Router is configured as Fail over but my client does not want this configuration. He wants to have both ISP's on the AP
There is limited wired connection for DVR and access control.

I hope this will help you:
