5.2 Driver Installation

After physical installation, you need to install the Wi-Fi and Bluetooth drivers for the adapter to function correctly.

1. Download Drivers: Visit the official FENVI website to download the latest drivers for the PCE-AX1800 model. The driver download link is: https://www.fenvi.com/drive.html?keyword=PCE-AX1800S
2. Extract Drivers: Once downloaded, extract the compressed driver files to a known location on your computer (e.g., a folder on your desktop).
3. Install Wi-Fi Driver:
   • Go to Device Manager (Right-click Start button > Device Manager).
   • Look for a "Network Controller" or "Unknown Device" with a yellow exclamation mark under "Other devices" or "Network adapters".
   • Right-click on it and select "Update driver".
   • Choose "Browse my computer for drivers" and navigate to the folder where you extracted the Wi-Fi driver files. Follow the on-screen prompts to complete the installation.
4. Install Bluetooth Driver:
   • In Device Manager, look for a Bluetooth device with a yellow exclamation mark (if not already installed).
   • Right-click on it and select "Update driver".
   • Choose "Browse my computer for drivers" and navigate to the folder where you extracted the Bluetooth driver files (often a separate subfolder within the main driver package). Follow the on-screen prompts.
   • Alternatively, run the setup executable provided in the Bluetooth driver folder if available.
5. Restart PC: After installing both drivers, restart your computer to ensure all changes take effect.

6. Operating Instructions

1. Once the drivers are installed, click on the Wi-Fi icon in your Windows taskbar (usually in the bottom-right corner).
2. A list of available Wi-Fi networks will appear. Select your desired network.
3. Enter the network security key (password) if prompted.
4. Click "Connect". Your PC should now be connected to the Wi-Fi network.

6.2 Using Bluetooth

7. Troubleshooting

If you encounter issues with your FENVI WiFi6 AX1800 adapter, refer to the following common problems and solutions:

• Problem: Bluetooth is not working.

  **Solution:** Ensure the 9-pin USB cable is securely connected from the adapter to a 9-pin USB 2.0 header on your motherboard. Without this connection, Bluetooth will not function. Also, verify that the Bluetooth driver is correctly installed in Device Manager. If a yellow exclamation mark is present, right-click, select "Update driver," and manually point to the extracted Bluetooth driver folder.

• Problem: Wi-Fi is not working or the card is not recognized.

  **Solution:**

  • **Check Physical Connection:** Ensure the adapter is firmly seated in the PCI-E slot and the antennas are securely attached.
  • **Driver Installation:** Verify that the Wi-Fi driver is installed. In Device Manager, look for "Network adapters." If you see an "Unknown Device" or a device with a yellow exclamation mark, install or update the Wi-Fi driver manually.
  • **M.2 Drive Conflicts:** Some motherboards may have M.2 slots that share PCI-E lanes, potentially causing conflicts. If you have an M.2 drive, try temporarily removing it or checking your motherboard manual for shared lane information.
  • **BIOS Settings (AMD Motherboards):** For some AMD motherboards, you might need to enter the BIOS/UEFI settings and adjust the PCI-E speed to "Gen3" (or 3rd generation) instead of "Auto" or "Gen4".
  • **Disable Built-in Wi-Fi:** If your desktop PC has a built-in Wi-Fi function, disable it in Device Manager or your PC's BIOS/UEFI settings to prevent conflicts with the new adapter.
  • **Restart PC:** Always restart your PC after making hardware changes or driver installations.
• Problem: Adapter not recognized after driver installation.

  **Solution:** Try refreshing the Device Manager. If the network card is still not recognized, disable any previous network card drivers (especially if you had a different wireless adapter) and restart your PC. The system should then recognize the MediaTek (MT7921) device.

• Problem: Does not work on AMD chipset motherboard.

  **Solution:** The adapter is designed to support AMD chipsets. If you face issues, ensure BIOS settings for PCIe are correctly configured (as mentioned above, setting PCIe speed to Gen3 might help). If problems persist, contact customer support.

• Problem: No Linux support.

  **Solution:** Currently, official drivers are only provided for Windows 10 and Windows 11. Linux support is not officially available from the manufacturer.

8. User Tips

• For optimal performance, ensure your router also supports Wi-Fi 6 (802.11ax) technology.
• Always download drivers directly from the official FENVI website to ensure you have the latest and most compatible versions.
• When upgrading from an older Wi-Fi adapter or built-in Wi-Fi, remember to disable the old adapter in Device Manager to prevent conflicts.
• If experiencing intermittent connectivity, try adjusting the orientation of the external antennas.
• Keep your Windows operating system updated to ensure compatibility and access to the latest network features.
