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.

It could be that the image you loaded is putting the LWAP into Mesh Mode, which will prevent it from joining a WLC.

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.

Thanks for the reply.  I haven't worked with wireless much, can you explain meshed mode?

Below is the image that was loaded on the AP:

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?

That looks good. It says the AP MODE is local, so its not a MESH mode problem. Have you also confirmed that your wireless LAN Controller is on the latest version of the software?

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.

So there's your problem.  You need to upgrade to at least v7.2.110.0 to enable 2602 compatibility.

I'd strongly suggest though that you go to at least v7.4.110.0, or any v7.5 code to ensure you don't experience some really weird bugs.
