We recently purchased the AP c9115axe-e and once we upgraded the firmware of WLC as cisco recomended we still cannot join the APs. What could be the issue?

- Ref : https://www.cisco.com/c/en/us/support/docs/field-notices/724/fn72424.html , note that for aireos controllers like 3504 , you need at least 8.10.18x.0 or later to resolve this issue (if the access point is 'affected')

Do you have console output from AP? Tjhis is the most valuable information to troubleshoot join problems.

With a console connected, reboot AP from scratch and log all ouput to a file and share please.

What version of software do you have installed on the WLC?

What version of software is the AP running (you'll get that from the console logs on the AP)?
