If you're having issues with your Fire TV stick connecting to your wi-fi, you can select Settings > Network from the Fire menu, then Play/Pause on your remote, and follow the recommended steps shown on screen.
If the connection issue persists try the following:
- Use the connectors and cables that came with your Fire stick.
- Confirm that you are using a Wi-Fi password and not an Amazon account password.
- Ensure your Fire stick is not located in an enclosed area such as a closet or cabinet that could block your Wi-Fi signal.
- Restart your Fire stick and any home network devices like modems or routers.
