If you wish to connect Chromecast without using Wi-Fi, the Ethernet Adapter for Chromecast lets you connect your Chromecast directly to your router through your wired Ethernet connection.

• A Chromecast device and a display with an available HDMI port
  
• A mobile device
  
• An Ethernet cable connected to a working internet router
  
• A standard household outlet or other source of AC power
  
• The Ethernet Adapter
  

1. Plug your Chromecast into any available HDMI slot on your display. Then, plug the Ethernet Adapter’s cable-end into your Chromecast device’s micro-USB port. Note: The Ethernet Adapter provides both power and internet connectivity to your Chromecast device.
   
2. Connect the Ethernet cable to the Ethernet Adapter. Note: Please be sure that the other end of your Ethernet cable is connected to a functioning router that has internet connectivity. The Ethernet Adapter won't provide internet access to your Chromecast unless it is connected to a working router with internet access.
   
3. Plug the Ethernet Adapter into the AC power source near the display to which you plan to connect your Chromecast. Note: The length of the power cord for the Ethernet Adapter is 78 inches (6.5 feet or 1.98 meters) so you'll need to be sure the power source is within that distance to your Chromecast device.
   
4. Open the Google Home app from the device you wish to set up your Chromecast with and follow the set up instructions. Important: When setting up Chromecast using an Ethernet Adapter, you can only use an Android or iOS device. You aren't currently able to set up your Chromecast using the Google Home app on Windows (either using Wi-Fi or hardwired).

Please note:

1. The Ethernet Adapter is designed for use only with Chromecast devices. Use with other devices may damage the device, your router, and/or your Ethernet Adapter.
   
2. The Ethernet Adapter may get warm; this is normal. If it gets hot, disconnect the Ethernet Adapter’s cable-end from your Chromecast and let the Ethernet Adapter cool before unplugging the Ethernet Adapter from the wall or resuming operation.
   
3. Don't expose the Ethernet Adapter to water or extreme conditions (moisture, heat, cold, dust), as it may malfunction or cease to work when exposed to such elements.
   
4. Don't try to disassemble or repair your Ethernet Adapter yourself. Doing so voids the limited warranty and could harm you, your display, your router, your Ethernet Adapter, and/or your Chromecast.
   
5. Your Ethernet Adapter is not designed, manufactured or intended for use in hazardous environments requiring fail-safe performance in which the failure of the Ethernet Adapter could lead directly to death, personal injury, or severe physical or environmental damage.
   
6. Take care when handling the Ethernet Adapter to avoid electric shock.
