Your Android device and your Chromecast or TV with Chromecast Built-In will establish a direct connection when you cast your screen.
For optimal performance when casting your Android screen, follow these steps,
1. Make sure that your Android device and Chromecast or TV with Chromecast Built-In are both connected to the same wireless network name (SSID)
- If connected via Wi-Fi, please check that the network name displayed on your TV is the same as the network that your Android device is currently connected to.
- AP isolation: Your Wi-Fi network configuration could prevent devices from communicating with Chromecast. In order to resolve this issue, you will need to disable AP (access point) isolation, also known as client isolation, on your router. Please refer to your router documentation to find out how to disable AP isolation.
- If you do not have access to your router settings or if you are attempting to connect through a guest, hotel or public network with AP/client isolation, you will be unable to set up your Chromecast.
Stuttering or poor qualityIf you are experiencing stuttering or poor quality when casting your Android screen, follow the steps below:
- The Android device and Chromecast device should be within ~4 metres (15 feet) of each other. The Chromecast or TV with Chromecast Built-In should be ~4 metres (15 feet) away from the router, or less.
- Make sure that both your Chromecast device and Android device are both connected to the same Wi-Fi network channel, either 2.4 GHz or 5 GHz.
- All devices running Android 4.4.2 or higher support the Cast screen feature. However, these Android devices have been tested to work best for Android screen casting. Other Android devices may not have the necessary power to provide an optimised screen casting experience.
If you are experiencing low volume when casting your Android screen, change the volume setting from the Google Home app:
- Download the Google Home app (if not already installed).
- Open the Google Home app .
- Tap your device, and then adjust the volume.
