the reason of AP reboot is " error heartbeat lost" all the switch is running on Poe and the switch is specifically for AP only the problem keep happening on peak hours 8 to 5 office hours.. i already upgrade the zd to latest version firmware.. please help..
Heartbeat loss is indication of potential network issue between AP/ZD. Ensure that during peak hours switch is NOT failling... During peak hours, run a ping test from laptop hooked to that same switch to controller and see how things.. Upgrading will NOT help unless its determined that code is causing problem.. btw how do you recover from the issue? do you reboot switch?
