Using a TFTP Server to Return to a Previous Release:-

This section does not apply to Cisco C3201WMIC and Cisco C3201LAP.

Follow these steps to revert from LWAPP mode to autonomous mode by loading a Cisco IOS release using a TFTP server:


Step 1 The static IP address of the PC on which your TFTP server software runs should be between 10.0.0.2 and 10.0.0.30.

Step 2 Make sure that the PC contains the access point image file (such as c1200-k9w7-tar.122-15.JA.tar for a 1200 series access point) in the TFTP server folder and that the TFTP server is activated.

Step 3 Set the timeout value on the TFTP server to 30 seconds.

Step 4 On the PC where the TFTP server is located, perform these steps:

a. Disable any software firewall products, such as Windows firewall, ZoneAlarm firewall, McAffee firewall, or others.

b. Ensure all Windows files are visible. From Windows Explorer, click Tools > Folder Options > View; then uncheck the Hide extensions for known file types check box.

Step 5 Rename the access point image file in the TFTP server folder to c1200-k9w7-tar.default for a 1200 series access point, c1130-k9w7-tar.default for an 1130 series access point, c1240-k9w7-tar.default for a 1240 series access point, and c1250-k9w7-tar.default for a 1250 series access point.

Step 6 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.

Step 7 Disconnect power from the access point.

Step 8 Press and hold MODE while you reconnect power to the access point.

Step 9 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.

Step 10 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.

Step 11 After the access point reboots, reconfigure it using the GUI or the CLI.

the entire process takes few minutes only to get completed. For More detailed information you can refer to the following link:-

Hi Vinay Sharma.

I would like to thank you about your document, but I have an AP 1142 and in your documentation you wrote was mentioned about 1200, 1130, 1240 and 1250 series AP.

Can I rename this file for 1140 series AP?

Best wishes.

Transmission Failed. Could not find file 'C:\TFTP-Root\c1140-k9w7-tar.default'

Dear Vinay.

Just one more question:

I am using this IOS version c1140-k9w7-tar.124-25d.JA. Which version it is correct? This one c1140-k9w7-tar.124-21a.JY.tar?

Unfortunately, I can't downloading any image, because my company lost our premier privilegious. So, this is my problem. I will try find this IOS using other methods.

Any way I would like to thanks your help.

Best regards.

I just need something cleard up, can you make a native 1142 LWAP to an autonomous AP using the same procedure? I've checked all of Cisco documentation and I don't see any explicit description for that particular model.

I am following the above procedures to convert my LWAPP 1130AG AP to Autonomous Mode but I have encountered problem. On the AP console port, I can see that the TFTP server sends the first block (512 bytes) to the AP and the AP sends Acknowledge Block 1. For some reason, the TFTP server does not see this Acknowledgement and sends the first Block again. The AP later shows "incorrect image file". I have use SolarWind TFTP server and the TFTP server on Ubuntu 10.10 TFTP-HPA with the same problem. I plan to use this TFTPd32 server tonight but does anyone see this problem before. Is it the TFTP server problem or the AP?

I had a switch with power over Ethernet.  I just put my computer and the access point in a local VLAN I created.  I then held the button for thirty seconds, and it started to grab the file right away.

Thanks,

Alex

Here is an Easy Tutorial for Conversion

https://www.youtube.com/watch?v=d7XTGGrUYBA

Even tough this procedure is old (made on 2011), I found that it is the most effective process to make the conversion very quick and effective. I did it on an AP 2702E no issues.

 

For those who want to make a conversion and have an AP with the "button mode", try this process and don't look something else

Hi,
Step by Step Process has been demonstrated How to of Convert Cisco Aironet 3600 Series Access Point from Lightweight to Autonomous version.

https://youtu.be/O2qNFVZ-KRQ

 

Requirements:
1.TFTPd64 Server
2.Cisco IOS Software AP3G2-K9W7-M for (C3600 Series AP)
3.The Cisco AP and the Laptop with TFTP server must be in same network.

According to my network setup
Lightweight AP BVI1 IP address is 192.168.1.4
Laptop's IP address where TFTP server is installed 192.168.1.7 [Default Router IP]

First disconnect the ethernet cable from the AP then Press the Mode button and Put back the ethernet cable to the AP and hold the Mode button Untill flash light turns to umber and Once the Lightweight AP goes to online then apply the following commands to convert it to Autonomous version:

set IP_ADDR 192.168.1.4 [According to my network setup]
set NETMASK 255.255.255.0 [According to my network setup]
set DEFAULT_ROUTER 192.168.1.7 [According to my network setup]
tftp_init
ether_init
flash_init
tar -xtract tftp://192.168.1.7/ap3g2-k9w7-tar.153-3.JH.tar flash:
dir flash
set boot flash:/ap3g2-k9w7-mx.153-3.JH/ap3g2-k9w7-mx.153-3.JH
set
boot
