In some cases, the SBG6400Â gateway may need to be reset to its factory default state and clear all of the previous settings. Â If the login for the Web Manager is unsuccessful,Â
the only option is to perform factory reset. Â The Factory reset can be performed by pressing the reset button or in the Web Manager. Â This document describes how to reset the SBG6400 to factory defaults by pressing the reset button or in the Web Manager.
CAUTION: This process will clear all configurations and should be use as the last resort.  Performing a Factory Reset will erase any configuration changes that have been made and requires the gateway to be reconfigured for Internet access.

- Press and hold down the Reset button for 15 seconds and then release it.
