Fortinet APs x 4 Model FAP231F stop broadcasting SSID randomly or not providing internet

[felipelarrota]

Good Morning, 

I have in my office 5 APs FAP231F connected to a Fortinet Switch and then to our Fortinet Firewall FW80. The FW provides DHCP to all our devices and then connect using IPSec Tunnel to our Domain Controller for DNS Services. A couple of months ago we updated configuration in the Firewall and activated antivirus and file filtering, ssl/ssh inspection and web content filtering. These are the only changes done recently and are my starting point for any possible changes in the environment that could be affecting my wireless network. I disabled all the fw security features I enabled a couple of months ago and seems to bring stability to the wireless network, yet in the last week I started experiencing the random issues of APs not broadcasting SSID or if connected to the SSID disconnecting from internet. Please find below our current AP configuration: Any help or guidance in what to do next would be much appreciated.

Hello @felipelarrota ,

Have you verified compatibility of FortiAP and FortiOS using https://docs.fortinet.com/document/fortiap/7.6.0/fortiap-and-fortios-compatibility-matrix/495193/for...?

Have your done any troubleshooting? any packet captures? tried disabling/enabling broadcasting of SSID?
