How can I fix Firmware upgrade hang up on AIR-AP1131AG

Answered Question
Dec 6th, 2009

Hello,

I recently tried to upgrade the IOS on the my 1131AG Wireless bridge using the Web interface. The upgrade hung up after few mins and now I can't access the AP's WEb interface and it blinking Green and Amber.

On the terminal I am getting this

Dec  5 17:23:42.983: %CAPWAP-5-DHCP_RENEW: Could not discover WLC using DHCP IP
. Renewing DHCP IP.
Not in Bound state.
*Dec  5 17:23:52.861: %DHCP-6-ADDRESS_ASSIGN: Interface FastEthernet0 assigned D
HCP address 192.168.200.104, mask 255.255.255.0, hostname AP001a.e26d.8244

Translating "CISCO-LWAPP-CONTROLLER.vsnl.net"...domain server (192.168.200.254)

LER.vsnl.net
*Dec  5 17:23:59.536: %CAPWAP-3-ERRORLOG: Could Not resolve CISCO-LWAPP-CONTROLL
ER.vsnl.net

- The device with IP 192.x.x.254 is my desktop PC from which I was upgrading the AP. The AP and my desktops are connected to a Linksys RV042 SOHO router that serves as a DHCP server too.

I am trying to revert back to the older version and I dont know how to do it. I am not an expert with IOS commands and my knowledge is very rudimentary. This setup is part of my home network setup. Any help to get this fixed in highly appreciated.

Pls. let me know if you need more info.

Thanks

Venkat

The easiest way to convert an AP from LWAP to autonomous is to use the Mode button method:

Using a TFTP Server to Return to a Previous Release

Ven,

Based on your output it sure looks like it your ap is good. What you have there is normal for an capwap AP trying to find a controller. Do you have a controller set up?

Go ahead log into the AP cisco cisco and enter the controller ip manuall by doing this (going off memory) lwapp controller ip address xxxxxx

This will join your AP the controller

If you hosed the firmware, you shouldnt be seeing that output at all.

Hi George,

The command is "lwapp ap controller ip address ".

Wait a sec ... How did Venkat upgrade the firmware???  Looks like Venkat upgraded the autonomous AP with a LWAP (rcv) image.

Yeah, thats the mistake I did. I dont have a controller setup and now I cant even get in to 'Config' mode. This is a standalone AP. I would like to get it back to the standalone mode so that it is useable.

Thanks

George,

     I can't even get in to the config mode. The config command is itself missing in the enable mode.I was using it as a standalone AP and do not have a controller setup. I was managing it using the Web interface.
