I'm working on LAN for a school building. So I have three MT AP's, all in the same pool (192.168.3.2/24 - 192.168.3.3/24 - 192.168.3.5/24). Each one of the AP's is correctly running a hotspot (virtual wireless interface, because we have a WPA2 on the same phisical radio interface) but I had to assign three different addresses (192.168.12.1/24 - 192.168.13.1/24 - 192.168.15.1/24). All of three AP's are served by a Radius Server (192.168.3.1/24), which runs also DHCP server for the LAN (192.168.3.2-192.168.3.250).
In this configuration a hotspot user connected in example to 192.168.12.1 will lose connectivity moving around the building (hotspot SSID are exactly the same), because his device will hook a different AP with a different pool.
I will appreciate very much if somebody could suggest how to have three different phisical AP's, three same hotspot SSID's, same hotspot dhcp pool, using a radius server on a fourth device.
Thank you very much.
