I recently downgraded our WLCs software from 188.8.131.52 to 184.108.40.206 but after that access point is not associated. I have searched some similar issues here but I cannot get the resolution. It seems that the flash of the AP is full and unfortunately I am not able to delete some files as recommended by others.
AP# sh flash:
Directory of flash:/
%Error oepning flash:/ (Invalid argument)
No space information available
-----got this error from show logging----
capwap_image_proc: encounter flash problem, retry here
----cannot issue delete command to remove some files----
% Unrecognized command
When I try to issue the "sh ver" to check the LWAPP image version, it is still showing version 220.127.116.11 and IOS 12.4(21a)JA2 since the AP join was not successful.
Re: AP does not associate after software downgrade
Thanks Steve. Just ignore this post as my AP has now successfully registered to the controller after I disconnect it to the network and reconnecting for a while. I've got no idea what was the real issue and I'm glad now it's back online. Thanks again.
