Hi Rajesh,

I have worked with others here on the forum that purchased LWAPP AP's and really needed IOS and they were able to convert them using this TFTP method and not using the WLC. (any problems they had were always associated to TFTP not the process itself)

The AP can be converted back to Autonomous (IOS) using the following method;

Reverting the Access Point Back to Autonomous Mode

Converting a Lightweight 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 and

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.

From this doc;

Hope this helps!

Thanks Rob for your prompt response...

I have seen this document before, it was mentioning only convert the autnomous AP to lightweight and back to autonomous. in my case, i m having an lightweight AP(with LAP partno), i wanna convert that to autonomos... so can i try the same method which explained in the given link?

Please advise

Hi Rajesh,

Yes, exactly. The nice thing about this process is that it can convert LWAPP AP's to Autonomous as well. I have done this myself and worked with others who have ordered LAP part #'s and really just needed IOS versions.

Hope this helps! You should be good to go,
