The next several pages are arranged by Internet Service Provider (ISP) or router manufacturer. For all changes to take effect,
you may need to restart your router/gateway or modem. Please check with your manufacturer’s documentation and follow the
steps outlined when making changes to the settings.
Note: Your screens may not match exactly, but this guide will show you the most common locations for these changes.
You can also go to your ISP’s or router manufacturer’s web site for updated information or refer to your router’s
documentation.
