LWAPP back to autonomous

Unanswered Question
Jul 23rd, 2007

I have received three LWAPP APs. The APs are native LWAPP, they were not converted from autonomous to LWAPP.


However, I need to convert them to autonomous mode. Is it possible?

Hi Rafael,


This happens to people all the time :) Here is a conversion method;


Reverting the Access Point Back to Autonomous Mode

You can convert an access point from lightweight mode back to autonomous mode by loading a Cisco IOS Release that supports autonomous mode (Cisco IOS release 12.3(7)JA or earlier). If the access point is associated to a controller, you can use the controller to load the Cisco IOS release. If the access point is not associated to a controller, you can load the Cisco IOS release using TFTP.


Using a TFTP Server to Return to a Previous Release


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 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, and c1240-k9w7-tar.default for a 1240 series access point.


Step 4 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.


Step 5 Disconnect power from the access point.


Step 6 Press and hold MODE while you reconnect power to the access point.


Step 7 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.


Step 8 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.


Step 9 After the access point reboots, reconfigure it using the GUI or the CLI.

The word "back" in your reply inplies the AP was once autonomous, it was converted to LWAPP, and now we want to go "back" to autonomous. Like the original poster, I also have an out of the box LWAPP (it's never been autonomous). Can I convert this to autonomous, even though it's never been autonomous?

Hi Bill,


Yes, this method can also be used for AP's ordered as LWAPP that you want to use in Autonomous mode. This is one of the nice features of this product is that the AP's can be switched back and forth :)


Hope this helps!

I have two 1242s that came to me in lightweight mode. The first one converted to autonomous mode with no problem using the steps above. The second one won't. The tftp server receives the initial request, but the AP doesn't download the image. Eventually the process times out.


Any ideas? I am using PumKin.

Hi Rob,


I followed these steps but I still couldn't convert my 1242 Lightweight to Autonomous AP. Is it necessary that the image is 12.3(7)JA or earlier? This might be a problem because Cisco is no longer giving possibility to download earlier version of the image.

Hi Ivan,


I don't think that the IOS being 12.3(7)JA or earlier would be the problem here. It is, however still available under "deferred" here;


Wireless > Cisco Aironet 1200 Access Point > IOS Software



More likely this is a TFTP problem, so watch the logs on your TFTP Server. Pay special attention to 3a and 3b below;



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 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 > Show hidden files and folders.


Step 4 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 5 Connect the PC to the access point using a Category 5 (CAT5) Ethernet cable.


Step 6 Disconnect power from the access point.


Step 7 Press and hold MODE while you reconnect power to the access point.


Step 8 Hold the MODE button until the status LED turns red (approximately 20 to 30 seconds) and then release.


Step 9 Wait until the access point reboots, as indicated by all LEDs turning green followed by the Status LED blinking green.


Step 10 After the access point reboots, reconfigure it using the GUI or the CLI.
