The Setup Wizard will guide you the most basic setup tasks, such as setting
an administrative password, selecting the type of WAN connection you have,
entering your computer's host name (if required by your ISP), saving the
configuration and restarting the router.
All other setup tasks can be accomplished using the configuration utility from
your web browser.
To use the Setup Wizard, click on the Run Setup Wizard link. This will
