5. Troubleshooting

If you encounter issues with your Fenvi AX900 adapter, try the following steps:

5.1 Adapter Not Recognized

• Re-insert the Adapter: Unplug the adapter and plug it back into the USB port.
• Try a Different USB Port: Connect the adapter to another USB 2.0 port on your computer.
• Restart Computer: A system restart can often resolve detection issues.
• Check Device Manager: In Windows, open Device Manager (search for it in the Start menu). Look under 'Network adapters' and 'Bluetooth' for the Fenvi AX900. If you see a yellow exclamation mark, it indicates a driver issue. Although it's driver-free, ensure your Windows installation is healthy.

5.2 Slow Wi-Fi Speeds or Disconnections

• Check Router Distance: Ensure your computer is within a reasonable range of your Wi-Fi router. Obstacles like walls can degrade signal quality.
• Switch Bands: If your router supports both 2.4GHz and 5GHz, try connecting to the other band. The 5GHz band offers higher speeds but shorter range.
• Interference: Other electronic devices (microwaves, cordless phones) can cause interference. Try to minimize these or move your computer.
• Router Settings: Ensure your router is configured for Wi-Fi 6 (802.11ax) if you expect maximum speeds.

5.3 Bluetooth Device Not Pairing or Connecting

• Ensure Device is in Pairing Mode: Refer to your Bluetooth device's manual to ensure it's correctly in pairing mode.
• Check Range: Bluetooth devices typically have a shorter range (around 10 meters or 33 feet). Ensure your device is close to the adapter.
• Remove and Re-pair: If a device was previously paired but isn't connecting, remove it from your computer's Bluetooth device list and then re-pair it.
• Interference: Similar to Wi-Fi, other wireless devices can interfere with Bluetooth signals.
