I have 3 ap groups. 1st Floor, 2nd Floor, and 3rd Floor and each group has an SSID "X" assigned to it with a different interface. The problem is, if I go to the 1st floor I get an IP, but as I go to the second, instead of getting a new IP and Subnet with the new VLAN I get the same one. I would like each floor to distribute a different IP and have the clients get that IP, as the goal of this whole thing was to decrease our BC domain.

- I assume you re-associate with the SSID for the particular floor ? Also check the involved DHCP server(s) logs, to check what is going on ?

Yes, it completely swaps WAPs, and as the client requests an IP the controller hands back the same one.

- That's not what I meant; you will only get a new IP if you associate with the SSID for that floor.

Alternatively (and a bad solution), create an SSID (with different name) per floor.

Not going to happen unless the floor is so thick it soaks up the signal and stops the WiFi from broadcasting between floors.
If this is remotely even possible, the next issue that will come up is for people to complain about "slow roaming".
Remember that the wireless client makes the ultimate decision to join whatever AP it "sees" as suitable. The wireless client may be on the third floor but it won't stop the same wireless client from joining an AP located on the ground floor.
