To Upgrade
IT IS VERY IMPORTANT TO NOT POWER-CYCLE THE UNIT BEFORE THE UPGRADE COMPLETES! IF YOU DO INTERRUPT THE UPGRADE, THE ROUTER WILL BE RENDERED USELESS!

  1. Using the Download Link below, download and extract the new firmware to a convenient place such as your desktop. The filename after extracting is FVS318N_v4.3.1-31.img

    Download Link: http://www.downloads.netgear.com/files/GDC/FVS318N/FVS318N-V4.3.1-31.zip

  2. Using a browser, login to the router as admin.
    Note: Reboot the firewall before beginning the update process.
  3. Select Administration > Settings Backup and Firmware Upgrade from the main/submenu.
  4. In the Router Upgrade section, click Browse.
  5. Locate the downloaded file and click Upload.
    This will start the software upgrade to your VPN firewall.  During the upgrade process, the Settings Backup and Firmware Upgrade screen remains visible and a status bar shows the progress of the upgrade process. The upgrade process can take up to 10 minutes. When the status bar shows that the upgrade process is complete, it can take another 10 minutes before the wireless VPN firewall reboots.
  6. When the reboot process is complete, log in to the wireless VPN firewall again. (If you can see the unit: The reboot process is complete when the Test LED on the front panel goes off.)
  7. Select Monitoring. The Router Status screen displays, showing the new firmware version in the System Info section of the screen.
