How do I connect my ET-3850 to a wireless network using the control panel?

Use the Wi-Fi Setup Wizard by selecting the network icon from the home screen, then selecting Wi-Fi (Recommended) > Start Setup > Wi-Fi Setup Wizard. Select your network name, enter your password using the on-screen keypad, confirm the settings, and select Start Setup to save. Note that the network name and password are case sensitive, including uppercase and lowercase letters, and numeric or special characters. (Page 36-37)
