What is the status and configuration status displaying for the AP in the SZ GUI under Access Point Monitor page? If the AP is connected the status should be "online" and if the configuration has been sent it should show configuration status "up to date"
You can check if the AP is configured for the AP's by SSH to the AP and run the command: get wlanlist
To further diagnose the problem download the AP support file, if the AP is online this is done by highlighting the AP and then from the "more" pulldown menu select "Download support log". If the AP is not online then you can generate and save this file from the AP SSH/CLI by turning on logging and running 2 commands: support (this generates the file) - support show (this scrolls the file to the SSH tool ofr logging). You will probably need to open a support ticket with Ruckus to get help in diagnosing the problem.
