Cisco 2504 wireless lan contoller not providing DHCP to wired lan

I have purchased my first cisco 2504 wireless lan controller that links into two Netgear managed switches. One switch is a GS728TP using POE for 15 AP's and the other switch is a Netgear GS748TP for a hard wired network. I am using the inbuilt DHCP server on the Cisco 2504 which is working fine for the wireless network but none of the wired clients are receiving IP addresses. I do not have any other means of supplying DHCP. Can anyone advise why this is - thanks in advance.

That wireless device has 3 Ethernet ports. When you connect directly to one of these ports, do you get an IP address?

1st, can you ping the controller from the switch
2nd, have you configured ip helper-address pointing to the 2504 ip address.

eg int vlan 1
ip helper-address 192.168.1.200

@John - The 2504 has 4 ports :-)

@VBOSS - The WLC can't do DHCP for wired clients unless you're using the wired guest feature.  You won't be doing that for a standard WLAN, so you'll need to use the router or proper DHCP server for wired clients.

He did, its not possible:

Note: A internal DHCP server pool will only serve the wireless clients of that controller, not clients of other controllers. Also, internal DHCP server can only serve wireless clients and not wired clients.

If you have a PC that is wired and always connected you could throw TFTP64 on it and use the DHCP server function.  Or use some other open source DHCP if a router or full blown DHCP server is not an option.
