Lose all connection from time to time
I have the following LAN setup
- Fortigate 80E device with a port with LAN role, DHCP configured and connected to the lan side
- 16 port Linksys unmanaged switch "Model lgs116"
- 5 D-link APs connected to the switch
the problem is from time to time all LAN connection become down for about 5 minutes and up again, can't ping the fortigate device or any other device connected via wireless or wired connection, and this happens many times per day.
also I have noticed that when using a network devices discovery tool link "Fing" app, it causes the problem. but it happens with or without the using the app.
Any help ?
Thanks in advance.
