5. Troubleshooting
5.1 Wi-Fi Issues
- No Wi-Fi Networks Detected:
- Ensure the Wi-Fi drivers are correctly installed. Check Device Manager for any yellow exclamation marks next to the network adapter.
- Verify that the antennas are securely attached to the card.
- Check if Wi-Fi is enabled in your operating system settings.
- Slow Wi-Fi Speed:

- Reduce physical obstructions between your computer and the Wi-Fi router.
- Update your router's firmware.
5.2 Bluetooth Issues
- Bluetooth Not Working/Not Detected:
- The Bluetooth function requires the internal USB cable to be connected from the wireless card to the motherboard's 9-pin USB header. Verify this connection is secure.
- Ensure Bluetooth drivers are installed. Check Device Manager for any issues.
- Check if Bluetooth is enabled in your operating system settings.
- Difficulty Pairing Devices:
- Ensure the Bluetooth device you are trying to pair is in pairing mode.
- Move the Bluetooth device closer to your computer.
- Remove and re-add the device in your computer's Bluetooth settings.
5.3 General Issues
- Card Not Recognized by System:
- Ensure the card is fully seated in the PCI-E slot.
- Try installing the card in a different PCI-E slot if available.
- Verify your operating system (Windows 7/8/10/11 64-bit) is supported.
- Driver Download Issues:
- If the included CD driver is not working or you don't have a CD drive, download the latest drivers directly from the FENVI official website: https://www.fenvi.com/drive.html?keyword=FV-AC1200.
