AIR-CAP2702I-A-K9 not connecting to WLC 5508

I have inherited some 2702i's. I reset the config using a console cable. When they reboot they detect our WLC and download all the configuration file - I can see them on the controller whilst they are doing this.

They then reboot and refuse to reconnect. They just constantly repeat this same error:

 

*May 7 11:00:28.607: AP has SHA2 MIC certificate - Using SHA2 MIC certificate for DTLS.

*May 7 11:00:28.000: %CAPWAP-5-DTLSREQSEND: DTLS connection request sent peer_ip: 172.16.227.245 peer_port: 5246

I have tried searching for answers on the internet without any success. In desperation I even erased the flash: and reinstalled the image from TFTP but it is still doing the same.

Re: AIR-CAP2702I-A-K9 not connecting to WLC 5508

Product/Model Number : AIR-CAP2702I-A-K9

Regulatory Domain of the AP is "-A" (USA). 

Configured Country............................... GB - United Kingdom

Regulatory Domain configured on the WLC is UK. 

This is why the AP won't join:  Regulatory Domain Mismatch. 
The AP needs to have a Regulatory Domain of "-E" to match.

Is also explains why the AP can/will download the config from the WLC but is unable to join the controller.

Re: AIR-CAP2702I-A-K9 not connecting to WLC 5508

I forgot to mention if I get a brand new 2702i out of the box and plug it into the same network point it registers itself just fine so it is something on these second hand AP's however I can't think what it can be as I have erased both the NVRAM and FLASH but still have this problem

Re: AIR-CAP2702I-A-K9 not connecting to WLC 5508

Is there a way to change domain on the AP or have the WLC accept American AP's ?

Re: AIR-CAP2702I-A-K9 not connecting to WLC 5508

You cant chnage the AP domain.

 

Just change the country code on WLC to US and then try again.

Presume you're aware that it would be illegal to use APs from a different regulatory domain in UK?
Obviously if you're actually using them in the US then that's fine.
