First, make sure your Apple TV is running tvOS 10 or higher. Then:
- Go to the App Store.
- Search for and choose DIRECTV STREAM.
- Select Get for free. If prompted, enter your Apple ID password.
When you set up your DIRECTV STREAM device at home, that location becomes the residential, non-mobile internet network associated with your device. This is called your home Wi-Fi network. Accessing the DIRECTV STREAM app on your Apple TV will also be limited to your Home Wi-Fi network. You can change your home Wi-Fi network up to 4 times within a 12-month period by relocating your DIRECTV STREAM device.
