Hello,

I have Cisco 2500 with 8.5.103 version and a AIR-CAP1702I-E-K9 AP on it. 

I upgraded WLC to 8.5.182 with aes and ap bundle file but AP is stuck on the downloading state.

I checked the logs on WLC :

Hi Leo,

Thank you for your answer.

I set the WLC time before Dec 2022 AP connected the WLC.

But that is only a temporary workaround @kdemir 

You need to upgrade to 8.5.182.7 - link below.
