Question

How do I reset my S33 cable modem back to the factory default settings?

Answer

In some cases, the S33 may need to be reset to its factory default state and clear all of the previous settings. If the login for the Web Manager is unsuccessful, the only option is to perform a factory reset. The Factory Reset can be performed by pressing the reset button on the device or through the Web Manager. This document describes how to reset the S33 back to the factory default settings using the reset button on the device or through the Web Manager.

CAUTION: This process will clear all configurations and should be used as the last resort. Performing a Factory Reset will erase any configuration changes that have been made and revert the custom admin password back to the last 8 digit of the serial number or password (default password). For assistance with Web Manager Access, refer to article # 18552 – S33: Web Manager Access.

Factory Reset with the Reset Button

Carefully insert the tip of a pen or the end of an unwound paperclip into the reset button located on the bottom, of the device.
Press and hold down the Reset button for 20 seconds and then release it.

Factory Reset in the Web Manager
