If you want to reinstate the configuration settings previously saved to a file, click Browse to locate the backup file on your computer, and then RESTORE to copy the configuration back to the Gateway.

For security purposes restoring the configuration does not change the password.

If you want to reset the settings on your Gateway to those that were loaded at the factory, click RESET. You will lose all your configuration changes. The Gateway LAN IP address will revert to 192.168.1.1, and the DHCP server on the LAN will be enabled. You may need to reconfigure and restart your computer to re-establish communication with the Gateway.

Upgrading the Firmware of your Gateway

The Upgrade facility allows you to install on the Gateway any new releases of system software that 3Com may make available.

3DES encryption is not shipped with the Gateway as standard due to international restrictions on encryption. If your country permits its use it can be downloaded from the 3Com web site at

Once you have downloaded the software, use the Browse button to locate the file on your computer, and then click on Apply.

You may need to change the file type in the dialog box displayed by your web browser to *.* to be able to see the file.

The file will be copied to the Gateway, and once this has completed, the Gateway will restart. Although the upgrade process has been designed to preserve your configuration settings, 3Com recommends that you make a backup of the configuration beforehand, in case the upgrade process fails for any reason (for example, the connection between the computer and the Gateway is lost while the new software is being copied to the Gateway).
