AP 1242AG can not register on WLC 4404

Hello!

I have few Cisco 4404 WLC controllers with 1242AG connected and 2 WISM 1. Everywhere is 7.0.252.0 software and country set as Russia Federations (RU). When I update WLC 4404 to 7.0.252.0 software version no one AP's can not register on controller. The error is 

failed to find matching cert.

No AP entry exist in temporary database

 but when I try to connect AP to wism - all work good. What I do wrong?

Console into the AP and post the complete output to the command "sh version".  The AP in question could be 10 years old and the MIC has expired.  This is a known issue.

MIC - it's a certificate? We have more then 180 items of 1242 AG. Is exist some mechanism to make changes on all APs ?

Field Notice: FN - 63942 - Wireless Lightweight Access Points and WLAN Controllers Fail to Create CAPWAP/LWAPP Connections Due to Certificate Expiration - Software Upgrade Required

Post the complete output to the command "sh version" because it's not just a software upgrade (on the controller) but there's a command involved as well.

I check you link. Not same like in my case. I have no any errors about cert expiration. Only one error in debug - is

failed to find matching cert.

No AP entry exist in temporary database

In log on controller 

Cause=New Discovery Status:NA

Cause=Heartbeat Timeout Status:NA

Is this same? Tomorrow will check AP console

I changed the system time on the controller, strange situation 1 of 3 test ap - register well but 2 other have a errors in controller log - Cause=Radio interface reset. Status:NA

Hi,

Your controller configured as:

Configured Country............................... RU  - Russian Federation

And your AP shows it is in Europe domain: 

Product/Model Number : AIR-AP1242AG-E-K9

I think either you need to change the country code on WLC or you need to replace 1242AG AP with -R- domain(AIR-AP1242AG-R-K9)

Regards

I do not think so. There is no country code Europe, only countries (Spain, Estonia, etc) and second one - i changed year to 2011 - all work well, if I changing it back and reload controller - same situation (AP cannot register)

Don't "add" European countries.  Remove "Russia" from the controller and see if the AP joins.

I agree with Sandeep (below).  The AP has the Regulatory Domain of Europe (-E) but APs for Russia must have the Regulatory Domain of "-R".

Which domain should I select? EE - Estonian, ES -Spain - but we talking about Country domain not about Regulatory right? Regulatory Domain is -AER on controller.

Choose any European country(example: Spain )on controller and then try again.

hiw to change country code:

I changed country to Germany and my reg domain is E but nothing changed. Nothing in controller log, no ap registered. But if I change year on controller to 2011 or 2012 - ap's successfully registered and work well. I think it's a mic certificate issue.
