I have a problem with a wireless deployment using cisco 1130AG access points and a 4402 WLC. The network setup composes of 2 branch offices. The main office has 3 APs together with the controller. The branch office has 5 APs which are all in the H-REAP mode. They want to use 3 SSIDs in the branch office each with its own VLAN and each has to obtain an IP from a local Windows 2000 DHCP server. I have already configured the 3 VLANs as well as the 3 SSIDs. One SSID worked well. Users can connect to this SSID and they are given an IP on a 192.168.137.0 subnet. In the other 2 SSIDs, users can't get an IP address. I have already configured trunk ports on the switch ports to which the APs are connected. I have also done the VLAN Mapping on the WLC. I don't know why in the other 2 SSIDs users still cannot get an IP. I have also tested on obtaining an IP from those VLANs or subnets in the LAN and there was no problem.
If anyone has already tried this, and has made it work, tell me the things that I should still do.
