Installation Guide

1. Hardware Installation

1. Power Off Your Computer: Before starting, ensure your computer is completely powered off and unplugged from the power outlet.
2. Open the Computer Case: Remove the side panel of your computer case to access the motherboard.
3. Locate an Available PCI-E Slot: Find an empty PCI-E slot on your motherboard. The Fenvi AX900 adapter requires a PCI-E x1, x4, x8, or x16 slot.
4. Insert the Adapter: Carefully align the adapter with the chosen PCI-E slot and press it firmly until it is securely seated.
5. Connect the Antennas: Screw the two included antennas onto the connectors at the back of the adapter.
6. Connect the Internal USB Cable: Plug one end of the internal USB cable into the adapter's USB header. Then, connect the other end of the USB cable to an available 9-pin USB header on your motherboard. This connection is crucial for Bluetooth functionality. Inserting it into the wrong port may damage the Bluetooth cable or motherboard.
7. Close the Computer Case: Once the adapter and cables are securely installed, close your computer case and reconnect the power cable.

2. Driver Installation

1. Power On Your Computer: Start your computer after hardware installation.
2. Obtain Drivers: For optimal performance, please download the latest version of the network card driver from the official Fenvi website: www.fenvi.com. You may also search for 'Fenvi AX900 driver' on Google.
3. Install Drivers: Follow the on-screen instructions to install the downloaded drivers.
4. Restart Computer: After the driver installation is complete, restart your computer for the changes to take effect.

Note: If the network card is not recognized or Bluetooth is not functioning after driver installation, try re-downloading and installing the drivers. Some users have found success using drivers for similar models like the 'XA900 Pro' if the specific AX900Pro driver causes issues with Bluetooth detection.

The Fenvi AX900 adapter supports Windows 10 and Windows 11.

Operating Instructions

1. Wi-Fi Connection

1. After successful driver installation, click on the Wi-Fi icon in your system tray (usually in the bottom-right corner of your screen).
2. Select your desired Wi-Fi network from the list of available networks.
3. Enter the network password if prompted and click 'Connect'.
4. Your computer should now be connected to the Wi-Fi network.

2. Bluetooth Connection

1. Ensure the internal USB cable is correctly connected to both the adapter and your motherboard's 9-pin USB header.
2. Go to 'Settings' > 'Devices' > 'Bluetooth & other devices' (Windows 10) or 'Settings' > 'Bluetooth & devices' (Windows 11).
3. Turn on Bluetooth.
4. Click 'Add Bluetooth or other device' and select 'Bluetooth'.
5. Put your Bluetooth device into pairing mode.
6. Select your device from the list and follow any on-screen prompts to complete the pairing process.

Troubleshooting

• Network card not recognized: If the network card is not detected by your system, ensure it is properly seated in the PCI-E slot. Try re-plugging the adapter. If the issue persists, re-install the drivers.
• Bluetooth not working: Verify that the internal USB cable is securely connected to both the adapter and an active 9-pin USB header on your motherboard. Bluetooth functionality relies on this connection. Re-check driver installation for Bluetooth.
• Driver installation issues: Always download the latest drivers from the official Fenvi website. If you encounter problems, try uninstalling existing drivers and performing a clean installation. In some cases, using drivers for a closely related model (e.g., XA900 Pro) might resolve Bluetooth detection issues.
• Slow Wi-Fi speeds: Ensure your router supports WiFi 6 (802.11ax) for optimal performance. Check for interference from other devices or physical obstructions. Ensure antennas are securely attached and positioned for best signal reception.
• Linux Compatibility: Please note that official Linux drivers may be limited or problematic. Users have reported difficulties with kernel compatibility. For Linux users, it is recommended to research community-supported drivers or consider alternative hardware if stable Linux support is critical.

Maintenance

To ensure the longevity and optimal performance of your Fenvi AX900 adapter, follow these maintenance guidelines:

• Keep it Clean: Periodically clean the inside of your computer case to prevent dust buildup on the adapter's heatsink. Dust can impede heat dissipation and affect performance. Use compressed air to gently remove dust.
• Ensure Proper Airflow: Make sure your computer case has adequate ventilation to allow for efficient heat dissipation from all components, including the wireless adapter.
• Firm Connections: Occasionally check that the antennas and the internal USB cable are securely connected. Loose connections can lead to intermittent performance issues.
• Software Updates: Keep your operating system and device drivers updated to benefit from performance improvements and security patches.

The adapter features strong heat dissipation for stable and reliable performance.

User Tips

• Bluetooth Functionality: Always remember to connect the internal USB cable from the adapter to a 9-pin USB header on your motherboard. This is essential for Bluetooth to work.
• Driver Management: It's a good practice to download and save the drivers to a USB drive or another accessible location before installation, especially for Windows 11, as the system might not detect the device initially without them.
• Performance Expectations: While the card offers excellent wireless performance, for the absolute fastest and most stable connection, a wired Ethernet connection is generally superior. However, for users who prefer or require wireless, this adapter provides a significant upgrade.
• Troubleshooting Drivers: If you face issues with Bluetooth after installing the official AX900Pro drivers, try installing drivers for the 'XA900 Pro' model, as some users have reported this resolves the problem.
