5. Operating Instructions
5.1 Wi-Fi Receiving Function
Once installed, the adapter allows your computer to connect to wireless networks. Simply select an available network from your operating system's network settings and connect. The adapter will receive the Wi-Fi signal from your router, enabling you to browse the internet.

5.2 Wi-Fi Transmitting (Soft-AP Mode)

7. Troubleshooting
If you encounter issues with your adapter, refer to the following common problems and solutions:
- Cannot achieve maximum speed: The actual speed can be affected by various factors including your network environment, router capabilities, physical barriers (walls, furniture), and your computer's internal memory/hardware. Ensure your router supports 600Mbps or higher to maximize the adapter's performance.
- Wi-Fi dongle suddenly unavailable: Open your computer's "Device Manager" and check if the adapter's driver is disabled. Re-enable it if necessary, or reinstall the drivers.
