Make sure your TV is connected to your home network. On your TV, select Settings, and then Network. Choose Network Status. You’ll see images of your TV, router, and internet as they connect in that order. Look for 3 dots between the images to show you’re connected. See an X? You’ve lost your connection.
Important: When you set up an AT&T TV device at home, that location becomes the residential, non-mobile internet network associated with your device. This is called your home Wi-Fi network.
