2. Reset the FortiGate and Network Devices

  • If there are network switches, wireless access points, or other intermediate devices, reboot them as well to ensure a full reset of the network path.


3. Verify Internet Connectivity

  • Temporarily disconnect the internet cable (WAN) from the FortiGate device.

  • Connect that cable directly to a computer/laptop.

  • Check if the computer receives an internet connection.

    • If yes: The issue is likely with the FortiGate device or configuration.

    • If no: The issue may be with the ISP, modem, or upstream equipment. Investigate further on that path.
