Hi Alejandro,
Good stuff!
You see this error during the upgrade:
FAILED Unable to Load the LWAPP Recovery Image on to the AP
When you see this error, complete these steps:
Verify that your TFTP server is properly configured.
If you use the Upgrade Tool embedded TFTP server, a common culprit is personal firewall software, which blocks the incoming TFTP.
Check if you are using the correct image for the upgrade.
The upgrade to lightweight mode requires a special image and does not work with the normal upgrade images.
Have another close read of this doc (especially the section deatailing the Upgrade Tool);

Hi Alejandro,
These AP's can be converted to LWAPP. We did this exact conversion last summer on about 30 1121G's with the **LWAPP upgrade tool**. Support for the 1121 was added in WLC version 4.0.155.0 Have a look at these related docs;
Software release 4.0.155.0 New Features
LWAPP for Cisco Aironet 1100 Series Access Points (802.11g radio only) Allows the Cisco Aironet 1100 Series Access Point to be upgraded from autonomous access point mode to lightweight mode using the autonomous to lightweight mode upgrade tool.
--------------------------------------------------------------------------------
Note You must install software release 4.0.155.0 on the controller before connecting 1100 series access points to the controller.

LWAPP Upgrade Tool Troubleshoot Tips
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_tech_note09186a008072d9a1.shtml
Access points must run Cisco IOS Release 12.3(7)JA or later before you use the upgrade tool.
System Requirements
You can use the Autonomous to Lightweight Mode upgrade tool to install Cisco IOS Release 12.3(11)JX on these access points:
**All 1100 series access points containing MP21G (802.11g) radios
All 1130, 1230, and 1240 series access points
All modular 1200 series access points running Cisco IOS software and containing these supported radios:
802.11g: MP21G, MP31G
802.11a: AIR-RM21A-x-K9, AIR-RM22A-x-K9
All 1300 series access points in access point mode
http://www.cisco.com/en/US/docs/wireless/access_point/ios/release/notes/b311jx1.html
Cisco has released a free tool called the "Autonomous to Lightweight Mode Upgrade Tool" that allows selected Cisco Aironet autonomous access point models to be configured for lightweight mode operation.
The Autonomous to Lightweight Mode Upgrade Tool supports the following models:
Cisco Aironet 1240AG Series access points
Cisco Aironet 1230AG Series access points
Cisco Aironet 1200 Series access points that contain 802.11g (AIR-MP21G-x-K9) and/or second-generation 802.11a radios (AIR-RM21A-x-K9 or AIR-RM22A-x-K9)
Cisco Aironet 1130AG Series access points
**Cisco Aironet 1100 Series Access Points that contain 802.11g radios (AIR-AP1121G-x-K9)
Cisco Aironet 1300 Series Access Points/Bridges (AIR-BR1310G-x-K9 or AIR-BR1310G-x-K9-R). A Cisco Aironet 1300 Series operating in Lightweight Access Point Protocol (LWAPP) mode only operates as an access point. This series does not support LWAPP bridging mode.
The Autonomous to Lightweight Mode Upgrade Tool supports a process to migrate an autonomous access point from autonomous mode to lightweight mode. Unlike a VxWorks to Cisco IOS Software upgrade, this process is a Cisco IOS Software upgrade to the existing Cisco IOS Software image-not an operating system "swapout". In converted access points operating in lightweight mode, Cisco IOS Software continues to run on the access point, while LWAPP is used to communicate with a wireless LAN controller. Since LWAPP supports automatic access point configuration, there is no need to retain or convert the original autonomous Cisco IOS Software access point configuration.

Hi Rob, i read a file that says i should get back my ap to autonomous and later convert again to LAP but now with a previuos version (12.3(11)JX), cus im using the 12.3(11)JX1, but now in the cisco web site the version 12.3(11)JX is not enable for download, can u help me?

Hi Alejandro,
12.3(11)JX1 is just fine :) I think we might be talking about about 2 seperate problems here. There is the Autonomous to LWAPP upgrade for the 1121 and then getting it to actually join the WLC.
What version of code are you running on the WLC?
Is this the only AP having trouble Joining the WLC?
Do you have any AP's up and running on the WLC?
Let us know,
Rob

What version of code are you running on the WLC?
the version is: 4.1.171.0
Is this the only AP having trouble Joining the WLC?
yes, i have 5 1131 and works good
Do you have any AP's up and running on the WLC?
yes, 5 1131
but i check the led status in a table and says: boot failure or IOS corrup.
1. i make the upgrade with the upgrate tool v5. the log file says: succesfull upgrade but the AP leds says:boot failure or IOS corrup.
2. i change the upgrade tool to one before v2, everything was fine at the end i check the log file and says, failue: unable to upload the LWAPP IOS.

Hi Rob, a little tip is to set the same time in the wlc and the AP.
