A:Answer You may want to check and try these steps and see if it'll resolve your concern:
- Your device(Android/iOS) and Chromecast device should be within 15 feet (4 meters) of each other. The Chromecast or TV with Chromecast built-in should be 15 feet (4 meters) away from the router, or less.
- Make sure both your Chromecast device and Android device are both connected to the same Wi-Fi network channel, either 2.4 GHz or 5 GHz.
- Reboot Chromecast by unplugging it from the power source. (Disconnect from power source not from TV's HDMI port)
If the above steps don't resolve the issue, you may try to perform a factory reset. Keep in mind that when you perform a factory reset, all info or data on your Chromecast will be deleted and you'll have to re-setup after.
