As if I didn’t have enough wireless fun this past week… I recently stumbled across an issue trying to get a number of new Cisco 2702i APs to join a Cisco 5508 Wireless LAN Controller. I didn’t realize it at the time but the reseller had changed the part number on my order from AIR-CAP2702I-A-K9 to AIR-CAP2702I-B-K9. The significance is the new -B regulartory domain that requires minimum of 8.0.132.0 software on the Cisco WLC to recognize the new AP models. As luck would have it the WLC I had was only running 8.0.121.0 software hence the APs were unable to join controller.
If you are going to be adding new APs you had better make sure that you upgrade the software on your WLC first.
Cheers!

It turned out we had to disconnect the APs for about 5 minutes to allow the DTLS cache on the controller to age out before the APs would join properly after upgrading the WLC.
Thanx for the heads up..i came across your site when i wanted my Avaya phones to work with the Avaya Switch 4800 series. I really got the help i needed thanx to you.
Thank you! I know this is an old post but this very post helped me to figure out why the heck we couldn’t get our APs to connect properly.
I happened upon the page by chance and this is what saved me another few hours of banging my head against the wall.
Due to this, I felt obliged to comment here and thank you :).
Hi Muhammad,
