Article: If your TV has a USB port, you can use it to power the Chromecast. Otherwise it will need to be plugged into the wall.  Use the INPUT or SOURCE button on your remote to switch. The HDMI port you connected your Chromecast to should be labeled for easy identification. Your Android device will need to be on the wireless network that you intend to set up your Chromecast on. To switch or select a wireless network, open the Settings app, tap Wi-Fi, and then tap your home network.            Newer Android devices will automatically enter the Wi-Fi password from your Android settings. If you're using an older device, you'll need to enter it manually. Once you're connected, you can use compatible apps like Netflix and Hulu to play video and music on your Chromecast. Tap the Chromecast button in the app and then tap your Chromecast name to begin playing content. Make sure your Android device is connected to your home wireless network, not the special network your Chromecast created during setup.
