Having pairing issues or missing your Chromecast icon? These tips may help:
Important: When you set up a Gemini (DIRECTV) 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 a Chromecast device is also 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 Gemini (DIRECTV) device.
