Thanks for that reply, and yes I understand that.
The exact issue I am having is that I have a few R600's all connecting to the ZD over WAN and I am receiving 'heartbeat lost' messages in the logs.
With devices connected using PSK it is fine always (no re-authenticating), but for windows devices connected using EAP the end users connection will be dropped requiring re-authentication at each 'heartbeat lost' event and PC restart.
Note: OS X, Android and iOS using EAP do not have to re-authenticate at each 'heartbeat loss' or device restart.
This 'heartbeat loss' was a major issue with my 'guest' SSID also but I found in the SSID's WLAN advanced settings an option called 'Grace Period' which I enabled and it seem's to have resolved the need to re-login constantly through captive portal.
There is no 'Grace Period' option on my 802.1x EAP SSID's advanced setting.
To be clear my internet connection is not dropping out ever, This issue seems to be only between the ruckus AP's at the WAN connection to the ZD.
Can you recommend anything I can do to improve the AP to ZD connectivity or reduce the sensitivity over WAN. Any help would be greatly appreciated in resolving this issue.
Just to be clear . . I'm not using RADIUS, IEEE 802.11x authenticates against the ZD's internal user database.
