Select the "Wireless" link underneath the "Home" tab. Enter a name in the "SSID" field to identify your wireless network.

For maximum security, enter a combination of numbers, letters, and symbols. Store your password in a safe place in case you ever forget it. Click "Apply" to save your settings.
