You are getting these messages because AP doesn't receive an IP address from the DHCP server that's why it's not able to join controller. You can use the below commands to configure static IP address:

debug capwap console cli ==> You need to enter this command before assiging IP address or make any change on AP via CLI

AP1240#lwapp ap ip address ==> Cmd to assign static IP address

AP1240#lwapp ap ip default-gateway ==> Cmd to assign default gateway

AP1240#lwapp ap controller ip address ==> Cmd to define IP address of controller

In case you want to convert this AP to autonomous mode, follow the steps mentioned on below link:

Please rate the post if it helps!

since it is CAPWAP AP, you should replaced  "lwapp"  with "capwap" keyword in Rakshit response.

If you already have a DHCP configured switchport, then connect this AP to that so it will get an IP automatically. Once you get an IP you have to register it to a controller, either using static method described in above response or any other method.

This should help you in that regard

I'm guessing you need to convert that AP especially if you don't have a WLC. Here are some instructions how to do that, but you probably don't have a service contract to download the right image. If you do have access to download the software, then these links will help you convert the AP's.
