WLC version:Software Version  8.0.120.0

I would like to know if this is a IOS version issue or other fact caused this.

 - Is the AP-model supported by the WLC software version ?

AP model:AIR-LAP1262N-T-K9, site has 20 APs, they are in same model. so I would take a yes.

[marce1000]

 - Appreciate the answer, but in this case  , I would let them extra verify this AP, to make sure that they didn't put a chicken between the ducks.

I would also upgrade to the latest 8.0 release, because yours has several known bugs and I think even some security issues.
See here for the release notes: https://www.cisco.com/c/en/us/support/wireless/5500-series-wireless-controllers/products-release-notes-list.html

thanks Patoberli,I would also intend to upgrade, but I guess I need a solid proof to share with my clients so this can be done.

[Steven24]

thanks!

8.0.120 supports that AP model, does it occur on any other AP's of the same model? have you done a bug search?

[Steven24]

thanks, Bernhard, I haven't done it yet, I guess bug serach only autherised by Cisco TAC?

[Leo Laohoo]

Raise a TAC Case.  This could be CSCtn41375.
