Hi Jibu Ninan Kurian,


Doesn't make a difference because once the LWAP joins the WLC, the WLC will distribute the full LWAP IOS to the APs.

Hi Jibu Ninan Kurian,


When you're dealing with WLC/LWAP the LWAPs firmware will be managed and distributed by the WLC.


For your AP to join the WLC, it must be running on an LWAP image.  The IOS "c1250-k9w7-tar.124-10b.JDA3" does NOT seem like a valid LWAP image.  You will need to upgrade the IOS from Autonomous to LWAP.  Here's the link:

Hi Jibu Ninan Kurian,


1.  For starters, I don't know what is the firmware of your WLC.  For 1250 to be supported, you need to use the firmware 4.2.207.0, 5.X or 6.X.  Frankly, I'd stay away from 5.X.
2.  To help you understand and configure your WLC, go through the Cisco Wireless LAN Controller Configuration Guide

If your LWAP rcv image is 12.4(21a)JA2 then you can operate both radios with 15.4w PoE.


LED blinking all colors (fast) means that it is trying or unable to join the WLC.  Can you console into the AP and find observe the logs?

Hi Jibu Ninan Kurian,


1.  Your LAP is a AIR-AP1252AG-E.  Is your WLC configured to allow this regulatory domain for Saudi Arabia?
2.  As in my earlier post, please don't confuse the "low power" because the AP is running on a "lite" firmware, the "rcv" lwap image.  Once it's able to successfully join the WLC, the WLC will "pump" the full LWAP image.  In your initial post, it seems that the WLC is running 5.2.193.0.  This version will not upgrade the firmware of the radio modules to operate both radios at 15.4w.
3.  According to both txt files, I can see the LAP getting an IP address from DHCP.  Do you have any other information?  We would like to see the logs regarding the why the LAPs are unwilling to join the WLC.
