FortiAP-231G intermittently goes offline.

[msteele73]

Hi,

I'm still learning my way around Fortinet products. My FortiAP-231G intermittently goes offline. It has happened 3 times now. The first 2 times I left it (I had to go away) and it came back. This time it went offline on Friday and has yet to come back. I have found and run diagnose wireless-controller wlac -c wtp and can see the last failure : 10 -- Wait Join timer expired. Not sure what this means or how to fix it. The power light goes from solid amber to flashing amber. It have tried restarting the AP but no good.

Any help is greatly appreciated.

My set up: Fortigate 40F (v7.4.5 build2702 (Mature)),  FortiSwitch 108F-POE (v7.4.2 build0801), FortiAP-231G (v7.4.3 build068). Fortigate and FortiSwitch are connected via Fortilink

Below is the full out of the diagnose command:

I would suggest to first check if there are any compatibility issues:

https://docs.fortinet.com/document/fortiap/7.6.0/fortiap-and-fortios-compatibility-matrix/495193/for...

If that part is fine, then go through the following article steps to identify the casue:
