Access point in Downloading status

[aidei0001]

Hi, 

I have recently installed a Cisco Aironet 1852I access point which is currently connected to a 3650 wireless controller. For some reason, the access point status shows as downloading in on the wireless controller and remains in this state. Please does any know why this is happening and how it can be resolved? Many thanks in advance for your assistance.

Hi,

 I´ve seeing this behavior before but fixed only restarting AP and let it try again. 

You can collect some logs from AP and WLC and share here, maybe we can see something wrong from logs.

 On the WLC you can run debug capwap and on the AP you can use a console cable and save the output.

Also, inform which WLC version you have, this is even more important then WLC model.
