Connect your device to the internet using a Wi-Fi connection.
INSTRUCTIONS & INFO
Open the Wi-Fi network manager on your computer or Wi-Fi enabled device. Note: For Windows PC, this is typically in the Start bar in the lower-right hand corner of your screen and for a Mac computer, under the Wi-Fi icon in the top right hand corner of your screen.  For other Wi-Fi enabled devices, such as smartphones and tablets, the Wi-Fi manager can typically be found under Settings.
Find and select the AT&T Home Base Wi-Fi network name (SSID) (e.g. ATT-HOMEBASE-XXXX).
Enter the Wi-Fi password found on the bottom of your Home Base.
Go to att.net (or your favorite website) to confirm your Internet connection.  When your device is transmitting to and from the Internet, the Wi-Fi light will flicker green.
