If you have 'Ruckus Unleashed' mobile app then it will send you a text message whenever a WiFi service affecting event takes place such as AP going offline, AP's radio gets turned OFF (likely done manually by someone), or WLAN gets disabled (likely done manually by someone) etc.
This is still a problem - even though there's an option for AP offline... and no way to change a threshold... In my searching, I see that if you have the multisite setup, you can set a threshold; but none of our clients use this.
in addition, the available threshold values aren't reasonable. We need alerts if a device is offline for more than 5 seconds... not 2 hours. by 2 hours, users are already in a bind and lost productivity.
