What do I need to complete the Setup Wizard?
To complete the Setup Wizard, you need a high-speed internet connection (wired or wireless), your WiFi network name and password, an internet browser, and a valid email address. If your wireless network is not visible, you can select Hidden Network and manually enter your network name (SSID).
