Maintenance
The COMFAST CF-983BE is designed for durability and efficient performance. To ensure its longevity and optimal operation:
- Heat Dissipation: The adapter features a dual-side heat sink design. Ensure adequate airflow around the device to prevent overheating, especially during prolonged high-speed usage.
- Antenna Positioning: For the best signal reception and transmission, ensure the external antennas are positioned optimally and are not obstructed by other devices or furniture.
- Cleaning: Keep the adapter free from dust and debris. Use a soft, dry cloth to gently clean the exterior. Do not use liquid cleaners.
- Storage: When not in use for extended periods, store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
Troubleshooting
1. Adapter Not Detected or Installed
- Check OS Compatibility: Ensure your system is Windows 10 (32-bit/64-bit) or Windows 11 (64-bit). The driver-free feature is specific to these operating systems.
- USB Port: Try plugging the adapter into a different USB port. Ensure the port is functioning correctly.
- Restart Computer: A simple restart can often resolve detection issues.
- Device Manager: Open Device Manager in Windows to check if the device is listed, even with an error. If so, try updating the driver manually (though typically not needed for supported OS).
2. Slow Internet Speed
- USB 3.0 Connection: Verify the adapter is plugged into a USB 3.0 port on your computer. USB 2.0 ports will limit the maximum speed.
- Router Compatibility: For speeds up to 6452Mbps, a tri-band WiFi 7 router is required. If your router is older (e.g., WiFi 5 or 6), the adapter will operate at the maximum speed supported by your router.
- Signal Strength: Check the signal strength indicator. Weak signals can lead to slower speeds. Adjust antenna position or move closer to the router.
- Interference: Other electronic devices (microwaves, cordless phones) can cause interference. Try to minimize these sources.
- Network Congestion: If many devices are using the network simultaneously, overall speed may decrease.
3. Frequent Disconnections
- Signal Stability: Ensure strong signal strength. Weak signals are a common cause of disconnections.
- Antenna Position: Adjust the external antennas for better reception.
- Driver Issues: Although driver-free, ensure your Windows system is up-to-date.
- Router Issues: Restart your wireless router. Check for firmware updates for your router.

User Tips
- Speed Optimization: To fully utilize the 6452Mbps speed capability, ensure you are using a tri-band WiFi 7 compatible router. The adapter's performance is also dependent on your internet service provider's speed.
- Linux/Monitor Mode: The COMFAST CF-983BE is officially supported on Windows 10/11 (64-bit). While some users may find success with community-developed drivers for Linux or monitor mode, these functionalities are not officially guaranteed or supported by COMFAST. For specific needs, it is recommended to research community support or contact COMFAST directly for advice.
- Signal Strength: Experiment with the orientation of the adapter's external antennas to achieve the best signal strength and coverage in your environment. Avoid placing the adapter behind large metal objects or thick walls.
- USB Port Choice: Always prioritize plugging the adapter into a USB 3.0 port for maximum data transfer rates. USB 2.0 ports will bottleneck the adapter's potential speed.
