« Go Back


How do I change my Wi-Fi Security Key in the SBG6400?

By default, the SBG6400 is setup to use WPA wireless security with the Wi-Fi security key (sometimes referred to as the wireless password).  The Wi-Fi Security key's string of character would need to be entered into a wireless client (such as a laptop or tablet) in order to have wireless connectivity.

At times, it may be desired to change the wireless key.  This can be accomplished by logging into the Web Manager of the SBG6400.  This document describes how to change the Wi-Fi security key.

NOTE: The SBG6400 is configured by default with a WPA wireless security.  To support legacy wireless devices using WEP wireless security please refer to the article # 15138 - SBG6400 (v1.3.x): WEP Wireless Setup (Primary Network).

To Change the Wi-Fi Security Key

  1. Launch a web browser, such as Internet Explorer, Firefox, or Safari. Enter into the address box, and press the Enter key.  The Login page will appear.

    NOTE: A security or private risk alert may appear on the web browser advising users to proceed with caution when accessing the Web Manager. There is no risk in proceeding to the Web Manager. For instructions to by-pass the alert screen, refer to article # 18181 - Alert Message for Web Manager Access.
  2. On the Login page, enter admin or a customized username in the Username field.
  3. Enter password or a customized password in the Password field.

    NOTE: On later versions of the SBG6400, the Wi-Fi Security Key is used as the default admin password printed on the bottom while label.  For assistance with Web Manager Access, refer to article # 18730 – SBG6400: Web Manager Access.
