Find tips to fix Chromecast streaming issues

Can’t synch Chromecast and your mobile device? Having trouble streaming the AT&T TV app? Learn ways to fix common picture, sound, and icon issues.


General tips

Try these options to fix many picture and sound issues with the AT&T TVSM app and your ChromecastTM device:
  • Launch the Google Home app, choose Devices, and Stop Casting. Then, cast again.
  • Try casting from another app. Launch the app and select Cast.
  • Unplug the power cord for your Chromecast device for one minute, plug it back in, and restart the device.
  • Check for updates to the AT&T TV and Google Home apps from the Google Play Store.
  • Restart your Android or iOS device.

Good to know: To cast content with Closed Captions from a mobile device to a paired TV, toggle the Chromecast-enabled mobile device screen.

Synching issues

No play or pause button? Closed captioning missing? Try these options if your device doesn’t sync within a few seconds of casting:
  • Select Casting (top, right corner of your device screen). Your screen should refresh and your program display.
  • Restart your device and then try casting from the app again.
  • Unplug the power cord for your Chromecast device for one minute and then plug it back in.

Pairing and icon issues

Having pairing issues or missing your Chromecast icon? These tips may help:
  • Confirm your Android or iOS device is compatible with the AT&T TV app.
  • Make sure your mobile device and Chromecast device are connected to the same Wi-Fi® network.
  • Close and reopen the AT&T TV and Google Home apps.
  • Check for updates for your Android or iOS device.
  • Unplug the power cord for your Chromecast device for one minute, plug it back in, and restart your Android or iOS device.

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. Accessing the AT&T TV 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 AT&T TV device.
