LWAP won't join LAN Controller
I have a Cisco 2504 LAN controller and 2602 AP's, I loaded the LW image onto 1 of the AP's and it gets a DHCP address from the controller and I can ping the controller from the from the AP but it will not join. I get and error on the AP that it can not resolve the WLC, I am configuring for a remote site and do not have a DNS server available at this time. Any help would be appreciated.

Thanks for the reply. I haven't worked with wireless much, can you explain meshed mode?
ASKER
Below is the image that was loaded on the AP:
ap3g2-9w8-tar.default
ap3g2-9w8-tar.default
Mesh mode is basically when an AP is acting as wireless bridge to one or more other APs. In that mode you will have trouble connecting it to a WLC. Were you able to check the mode it is operating in from the console cable?

Here are the results from the AP:

What version of code do you have on the 2504 WLC? You need at least v7.2.110.0 to join a 2602 AP.
If you install a new image on an AP it won't go straight into Mesh mode. You 'have' to join it to a WLC first to configure it in Mesh mode - unless it was already in Mesh mode to start with.

Have you connected a console cable to the LWAP to see what the logging messages are reporting?
Also, if you connect to the LWAP with a serial cable you can login to the LWAP and run "show capwap client rcb" which should will say whether or not you are in Meshed mode.
Other reasons for a LWAP not joining a WLC could be country code or territory mismatched. Time/date might be really far off as well. Or it is having a problem with the cert on the WLC.
