- Restart both the Unitek R36 adapter (by unplugging and replugging power) and your source device.
- Lag or Poor Picture Quality:
- Ensure your source device and the adapter are using the 5G Wi-Fi band for better performance, if available.
- Reduce the distance between your source device and the adapter.
- Close unnecessary applications on your source device to free up resources.
