AP has a default AP reboot timeout of 30 minutes when it CAN NOT reach it gateway and hence AP will reboot if the gateway is not reachable for more then 30 minutes. Isolate the issue on the network that is preventing AP to reach the gateway and meanwhile change the AP Zone setting > Advanced Options > AP reboot timeout > "Reboot AP if it cannot reach default gateway after" to "0".
Thanks for your response. by gateway do you mean the controller IP or the default gateway? from the Smartzone controller, the below is the Alarms am getting from H500 and R700 access points
AP RuckusAP@F0:3E:90:09:04:00 was rebooted by the system because of AP lost Gateway more than 1800 seconds
Thanks for your contribution. i have realized from the AP network i can only ping the controller IP from the same network but not the default gateway. controller and APs are in the same network, I can ping the controller but not the default gateway. Could this be the problem?
