4. Operating Instructions

4.1 Connecting to a Wi-Fi Network

1. Enable WiFi: Ensure your computer's WiFi is enabled. The adapter's indicator light should be on.
2. Access Network Settings:
   • Windows: Click the network icon (usually a WiFi symbol) in the system tray.
   • macOS: Click the WiFi icon in the menu bar.
3. Select Network: From the list of available networks, select your desired WiFi network (SSID).
4. Enter Password: If prompted, enter the network security key (password) and click 'Connect'.
5. Verify Connection: Once connected, the network icon will indicate a successful connection.

4.2 Using AP Mode (Simulated Access Point)

The CF-924AC can function as a simulated Access Point (AP), allowing other devices to connect to your computer's internet connection wirelessly. This is useful in environments where a router is unavailable but an internet connection exists (e.g., wired connection to your PC).

1. Install AP Software: Ensure the necessary AP software (usually included with the driver package) is installed on your computer.
2. Enable AP Mode: Open the COMFAST utility or your operating system's network settings and enable 'AP Mode' or 'Mobile Hotspot' functionality.
3. Configure AP Settings: Set a network name (SSID) and a password for your new wireless network.
4. Connect Devices: Other devices (phones, tablets, laptops) can now search for and connect to the WiFi network broadcast by your CF-924AC adapter.

5. User Tips

• Utilize USB 3.0: Always connect the adapter to a USB 3.0 port for maximum speed and performance. USB 2.0 ports will limit the adapter's potential.
• Antenna Positioning: Experiment with the antenna angles. Rotating them can significantly improve signal strength and stability, especially in environments with obstacles.
• Choose the Right Band: For high-bandwidth activities like gaming or 4K streaming, connect to the 5GHz band if your router supports it. For better range and wall penetration, the 2.4GHz band is often more suitable, though it may be slower and more prone to interference.
• Driver Updates: Periodically check the COMFAST website for updated drivers to ensure optimal performance and compatibility with the latest operating system versions.

6. Troubleshooting

6.1 No WiFi Connection / Adapter Not Detected

• Check USB Port: Ensure the adapter is securely plugged into a functioning USB port. Try a different USB port.
• Driver Installation: Verify that the drivers are correctly installed. Reinstall drivers if necessary.
• Device Manager (Windows): Check Device Manager to see if the adapter is listed without any error symbols.
• Restart Computer: A simple restart can often resolve detection issues.

6.2 Slow Speed / Intermittent Connection

• USB 3.0 Port: Confirm the adapter is connected to a USB 3.0 port.
• Antenna Position: Adjust the antennas to optimize signal reception.
• Router Distance/Obstacles: Move closer to your WiFi router or reduce physical obstructions (walls, large furniture).
• Interference: Other electronic devices (microwaves, cordless phones, Bluetooth devices) can cause interference, especially on the 2.4GHz band. Try switching to the 5GHz band if available.
• Router Settings: Ensure your router is configured for optimal performance (e.g., correct channel, latest firmware).
• Dual-Band Advantage: Single-band adapters often suffer from lower speeds and more interference. The CF-924AC's dual-band capability helps mitigate these issues.
