6. User Tips

• Optimal Performance: For the best experience, especially when using the 5GHz band, ensure your computer's USB port is USB3.0 compatible.
• Windows XP Users: While the adapter supports Windows XP, it is an older operating system and is no longer officially supported. For better performance and a smoother experience, it is recommended to use the adapter with Windows 7, Windows 10, or newer systems.
• Signal Strength: If you experience weak signals or slow speeds, try adjusting the adapter's antennas to different angles.
• Dual-Band Selection: The 2.4GHz band offers better penetration through walls and longer range, while the 5GHz band provides faster speeds and less interference in closer proximity. Choose the band that best suits your environment.

7. Troubleshooting

• Adapter Not Recognized:
  • Ensure the adapter is fully inserted into the USB port.
  • Try a different USB port on your computer.
  • Restart your computer.
  • For Linux users, ensure the correct drivers have been downloaded and installed.
• No Internet Connection:
  • Verify that your router is working correctly and broadcasting a WiFi signal.
  • Check if you have selected the correct WiFi network and entered the password accurately.
  • Ensure your computer's network settings are configured to use the wireless adapter.
• Slow Speeds or Frequent Disconnections:
  • Adjust the adapter's antennas to improve signal strength.
  • Move closer to your WiFi router.
  • Try switching between the 2.4GHz and 5GHz bands if your router supports both.
  • Ensure there are no major obstructions (e.g., thick walls, large metal objects) between the adapter and the router.
  • Check for interference from other electronic devices (e.g., microwaves, cordless phones).
