Config storage confusion 2504 controller with CAP702I

Question

HI all,
I've been tasked with the rollout of the above mentioned hardware, and I've managed to get so far, but it seems I cannot do a 'copy running-config startup-config' on the CAP702I Aironet access points.
ive got then registered with the controller and radios turned on but the problem is that it the power is cycled the radios turn off, I can SSH into each AP and manually turn them on and it works all fine except I shouldn't need to do that.
If anyone could give me a clue as to how to change the ap config to either store the config with radios enabled on restart on the device itself or guide me through storing the config on the 2504 controller and pointing to it on the ap devices for their startup, it would be much appreciated.

So simply wireless clients are not getting ip address from the DHCP scope defined for them on AD DHCP server.
few  facts about DHCP handling on WLC:
- With DHCP proxy enabled , the controller acts as relay agent.
Simply you configure primary or may be secondary DHCP server under the interface config.
When the client starts the DHCP process the controller will rekay the clients DHCP packets
in unicast form.
- With DHCP proxy disabled , the controller will not intervene at all, and the client traffic will be sent
as broadcast. If the DHCP server is on different VLAN , you have to configure relay agent under the gateway
of the client vlan so that it can reach the DHCP server.
