For macOS Users

No official drivers exist. You can try the open-source HoRNDIS or Wireless USB Adapter drivers from Chris1111 on GitHub, but stability is not guaranteed for this specific model.

4. Troubleshooting

• "Device not recognized" error: Try using a different USB port. If you are using a desktop computer, try a port on the back of the tower (directly on the motherboard) rather than a front-panel port, which may have power delivery issues.
• Connection Drops: Ensure the driver is up to date. If you have recently updated Windows, you may need to re-install the QHMPL driver to resolve conflicts.

Stability Issues: Some owners reported that the device can automatically disconnect after 2–3 hours of continuous use, suggesting potential overheating or driver instability during heavy tasks.
