Hey,
I got a set of dhcp pool in one 3750 attached to diferent Vlans in the network, the wired network works fine, you can get from any switch port across the LAN a diferente VLANs IP. In my wlc2504 I got 5 WLANs with the DHCP server pointed to the VLAN in the 3750, but I just got one set of ip when i tried to connect to diferent WLAN, without connectivity, I can see all the Ap's, and ping the VLANs in the 3750,
any clue?

Probably there is a problem with the trunking between the 3750 and the WLC and/or AP's.
Check this link for a sample setup:

Thanks for answer
this the config in the 3750 port
interface FastEthernet1/0/24
switchport access vlan 9
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2-9
switchport mode trunk
this is the dhcp pool config for the Ap's
ip dhcp pool Core
network 192.168.9.0 255.255.255.0
dns-server 192.168.100.20
default-router 192.168.9.1
option 43 hex f104.c0a8.0905
lease 8
this another dhcp pool
ip dhcp pool Guest
network 192.168.5.0 255.255.255.0
default-router 192.168.5.1
dns-server 192.168.100.20
lease 8
and continue just getting Ip's in the 9.x range

Hi,
I think you issue is your switch interface config
interface FastEthernet1/0/24
switchport access vlan 9
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 2-9
switchport mode trunk
Try changing this to
interface FastEthernet1/0/24
no switchport access vlan 9
no switchport mode access
switchport trunk encapsulation dot1q
switchport mode trunk
switchport trunk allowed vlan 2-9

actually I got it, the problem was, in order to match wlans with vlans, we need to create the Vlans in the WLC like interfaces, under the Controller tab,
switchport access vlan 9 is just for security, just let connect devices in that VLAN
thanks a lot for the comments and help
