Re: DHCP Option for WLAN Controller in IOS

You have an issue with the DHCP or the AP. if the ap has joined the WLC already, it should fine the WLC after it gets an dhcp address. If you manually configure its with a static and it joins, then removing the static and the ap getting a successful dhcp address it should find the WLC.

Try connecting a laptop to that port and verifying it works and it switch the port around. You can also console into the ap while you reboot it as that shows exactly what's happening. If your ap constantly request an IP address, then you need to figure out why.
