FortiAP 21D Rebooting automaticly every 2 - 3 hours

[Holy]

Hello Guys ,

i have a problem in one branch with FortiGate50E 5.4.1 and FortiAP21D , it is the only one AP in this branch with 2 SSID´s.

the problem is this AP Reboots every 2 - 3 hours i dont know the reason why. 

i see it on Monitor > Wifi Health Monitor > AP Status.

today i upgraded the Firmware to the latest 5.4.1 build but that didn´t helped a lot, it still rebooting for no reason.

i have in another branch exactly the same Scenario, there is a 50E 5.4.1 and a FortiAP 21D and it works perfect, the AP is always UP and does not reboot himself.

Do anybody know what what the problem might be? and how to troubleshoot it?

Thank you

Nice post. Did you ever get this issue resolved? Did you end up RMAing or did you find the root cause?
