  2. Find and connect to the Wi-Fi network named "MiraScreen [SSID]" (e.g., MiraScreen BP93A200 or MiraScreen BF9EFE29) using the displayed password (e.g., 12345678).
  3. Once connected, open a web browser on your mobile device and enter the IP address displayed on the MiraScreen setup screen (e.g., http://192.168.203.1). This will open the dongle's settings page.
  4. On the settings page, select "Internet" or "Wi-Fi" to scan for available Wi-Fi networks.
  5. Choose your home Wi-Fi network from the list and enter its password to connect the dongle to the internet. This step is crucial for accessing online content and for firmware updates.

General Care

  • Keep the device in a dry environment and avoid exposure to moisture or extreme temperatures.

  • Clean the device with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials.
  • Ensure proper ventilation around the dongle during operation to prevent overheating.

Troubleshooting

If you encounter issues with your YEHUA Wireless Display Adapter, please refer to the common problems and solutions below:

Problem Solution
No display/signal on TV.
  • Ensure the dongle is securely plugged into the HDMI port.
  • Verify that the USB power cable is connected and receiving sufficient power (5V/2A recommended).
  • Check if your TV/projector is set to the correct HDMI input source.
  • Try plugging the dongle into a different HDMI port or a different display device.
Cannot connect to the dongle's Wi-Fi (SSID).
  • Ensure the dongle is powered on and the setup screen is visible on your TV.
  • Double-check the SSID and password displayed on the TV screen.
  • Restart the dongle by unplugging and re-plugging its power cable.
  • Ensure your mobile device's Wi-Fi is enabled and scanning for networks.
Lag or poor streaming quality.
  • Ensure the dongle is connected to a stable and strong Wi-Fi signal. Move closer to your Wi-Fi router if possible.
  • If using the dongle's internal Wi-Fi for direct connection, ensure your device is close to the dongle.
  • Reduce the distance between your casting device and the dongle.
  • Check for any obstructions (walls, large objects) between the dongle and your Wi-Fi router/casting device.
  • Ensure your mobile device has sufficient processing power and battery life.
Cannot cast certain apps (e.g., Netflix, Hulu).
  • Some streaming services (like Netflix, Hulu, Amazon Prime Video, Disney+) have Digital Rights Management (DRM) protection that prevents direct screen mirroring from mobile devices.
  • For these apps, you may need to use the app's built-in casting feature (e.g., Google Cast/Chromecast icon within the app) if supported by the dongle, or use a dedicated streaming device.
  • The YEHUA dongle supports DLNA/Airplay/Miracast. For Netflix/Hulu, it typically requires casting directly from the app's built-in cast function, often via Google Home app for Android.
Dongle gets hot during use.
  • It is normal for electronic devices to generate heat during operation.
  • Ensure the dongle has adequate ventilation and is not covered or placed in an enclosed space.
  • If overheating causes performance issues, try disconnecting it for a short period to cool down.
