Hello,

Had an issue joining a Cisco 2800 AP to a Cisco Wireless Controller

So the first thing to check is country code of the AP and controller and the time.

The AP is a -E and the country is on the controller:

Time looks ok:

To the console!!!

debug capwap errors enable

Looks like this controller version 8.0.133.0 isnt compatible with 2800s:

Time to upgrade.

First check the APs are compatible with the version you are going too:

Looks ok.  Next download it (oh also download the code you currently have installed in case you need it!) and while you’re waiting backup the controller config:

Before you reboot, go to the CLI:

Check the version:

Show boot

Show ap image all

Pre-image the APs:

config ap image predownload primary all

Check the progress:

Reboot the controller via the GUI.

Done:
