    Sorry, 

    yes 

    All computers are in the same subnet 192.168.1.0 / 24
    Fortinet:
      LAN address Fortinet: 192.168.1.1 (Gateway) 
      WAN address Fortinet: 192.168.90.253
     LAN address router: 192.168.90.254

    okay. Are all your PCs connected to fortigate directly and das the fortigate have switch configured?

     

    Basically: traffic inside one subnet (which traffic between your PCs is) does not hit the default gw as every client does have a route for the subnet with having one interface that carries the subnet. So this can neither be an issue with policies nor routing on your fortigate. 

    That to me looks more like if your ports are somehow isolated and cannot "see" each other.

    Sometimes other devices interfere with your wireless network. If you connect with ethernet (the yellow cord) and the problem goes away, you probably have a wireless issue.
