1852 failed to join WLC

Hi all,

I have few 1852 AP that suddenly failed to work with WLC2504 - 8.5.140.0

 

I tried to upgrade the AP to a different version and reinstall the 8.5.140 but nothing, same failure:

Someone had this?

 

I have other APs in the same model that works fine - AIR-AP1852I

Also:

AIR-CAP1602I

AIR-CAP1702I

Re: 1852 failed to join WLC

AP behavior seems similar to the reported bug "CSCvf71074", even though 8.5.140.0 is not listed as affected. 

 

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCvf71074

 

There is no workaround for this bug, but you can try upgrading the code to 8.5.151.0 and test.

Time and date is incorrect.
Post the complete output to the WLC command "sh time".

Ok.
Console into the AP and reboot the AP.
Post the entire boot-up process.

Re: 1852 failed to join WLC

I finished with the upgrade, all AP UP, including the other 1852.

But still other 1852s can't join...

Re: 1852 failed to join WLC

I'm going to agree with the other two comments. You're hittig CSCvf71074 or CSCvh85082.
If you look at the attachment of the boot-up process, during the first 5 seconds you are presented to interrupt with the boot-up process. Do so with the "Esc" key. And then do the following:

 setenv BOOT part1
 saveenv
 boot

Hope this helps.

Re: 1852 failed to join WLC

Hi,

I tried this but it booting up with part2.

 

I will upgrade the AP with mobility express img and update.
