I have an Mikrotik RB201iL as principal router and 4 Mikrotik WAP AC 2.4&5GHz wired connected to the main router. The idea is to use that 4 Mikrotik WAP AC as an extension for wireless internet access and I need to have one SSID for connection (a single SSID to be visible to the wireless network). Each wireless device which is connected to the network must see one SSID with the same security profile for all the AP. Please can anybody help me how to do this? What I have tried I see the same SSID four times.
