(code 2) Failed in association procedure means "Previous authentication no longer valid".
Make sure you are using the right credentials for connecting the SSID.
Is this the first time you are connecting the client to this SSID?
Is this a normal SSID or Guest/Hotspot SSID?
Can you try creating a new WPA2 SSID and see if it works?
I figured it out. I changed it from standalone to unleashed but for some reason the firmware did not take. I did a CLI reset and started over. The menus are working better and I can access the internet. Just something screwy happened. I think the AP was not previously reset correctly and old settings were stuck causing the firmware change to be faulty.
