A regular update of the firmware is important for a safe operation of the router.

In addition to updating the firmware automatically, you can also update the firmware manually. This Configuration Guide shows you how to update the firmware of your router manually.

The description in this Configuration Guide follows a configuration in the new user interface (web interface) available from icom OS 5.5.


Your router is not configured for automatic updates and you want to update it with the latest firmware.


To update the firmware manually, you must first download the latest firmware to your computer and then upload the firmware to the router and activate it.

Downloading the firmware

  1. Open the Release Notes page and click on   menu right white  Firmware Download  .

  2. Download the appropriate firmware packet to your computer.

Note For a manual update you need an Update Package for Manual Update. There is an incremental package and a full package. Use the incremental package if the firmware of your router already has the same major version (same first digit of the firmware version in front of the dot). Use the full package if the major firmware version of your router is an earlier one or you do not know it.

Updating the router

  1. Open the user interface of the router in a browser:

  2. If your router is in default settings and the splash screen opens, click under cog Manual configuration on To the manual configuration; otherwise log in to your router as configured.

  3. Open in the menu the cog AdministrationFirmware page.

  4. Click on file upload in the top right corner and upload the firmware packet to the router.
