Unable to downgrade AP's

Dustin Anderson

So, our admin updated our primary controller from 8.2.141 to 8.3.112 and moved AP's over to it.

We have reports of some laptops having connection issues, so we decided to move a couple APs back to the secondary controller to see if the change was the cause.

But, the APs join the secondary, then get into a download/reboot cycle that never ends. We have to CLI to them and point them back at the primary to stop it.

So, our admin updated our primary controller from 8.2.141 to 8.3.112 and moved AP's over to it.

Is/Are the AP in question either one of these: 

    • AP802
    • Cisco Aironet 1530 Series AP
    • Cisco Aironet 1550 Series AP (with 64-MB memory)
    • Cisco Aironet 1550 Series AP (with 128-MB memory)
    • Cisco Aironet 1570 Series APs

If the answer is yes, then read this: Changes in Images and Installation Procedure for Cisco 2504 WLC, Cisco 5508 WLC, and Cisco WiSM2

2602, 2702, 2802, and 3502

I've tried on the 2602 and a 3502.

I'd like to say "reboot the controller" but I'd rather recommend "upgrade to 8.3.121.0" instead.
