%Error opening lwapp:/c1140 (Incorrect Login/Password)

Console into the LWAP and in enable mode use the command "clear lwapp private" and reload the LWAP.

Try disconnecting the AP from the network. Assuming you are using PoE, then you'll need to find a power source for the AP (perhaps a standalone switch not connected to the network).

You'll need to hit the enter key to get the prompt to show up.

Hi Robert

I upgradrd the image to .

I have disconnected the Ap from the network connected using power adapter. But still I am getting the error messages logs and is not showing the Ap prompt:

Before trying the stuff below, you might want to connect your AP back to the network, go to the controller CLI and issue the following command:

debug capwap detail enable

Watch watch messages are displayed when the AP fails to join.


I can't my docs on how to do this, so I can't be sure these instructions are corrent...

You may want to try and clear all the LWAPP/CAPWAP configuration that the AP has learned. While holding in the mode button, apply power to the AP (release the mode button after about 5 seconds). Via the console port, you should be able to get to a command prompt. Go to enable mode (password should be "Cisco" or "cisco" [without the quotes]. Once in enable mode, try issuing a "clear lwapp private-config" command. If that doesn't work, try working through the CLI help to see what clear options you have. You then might want to try and manually set up the AP. Sample commands to give it an IP address and point it towards a WLC are below.

#clear lwapp private-config

#lwapp ap hostname mynewap

#lwapp ap ip address

#lwapp ap ip default-gateway

#lwapp ap controller ip address

Hi Rob,

"But iam not able to execute the command"

This got me stumped. How come it's possible to console into the AP but can't type any commands. Bizarre.

Robert.N.Barrett_2 Fri, 10/09/2009 - 10:59

Yeah, that's a new one for me. I hope that either the steps above fix the problem, the hardware is bad, or we hear a loud "Doh!".

Hi Robert,

The issue is resolved .. I have done 3 -4 times factory reset and finally it goy asscociated to one of the controller ...
