System Requirements:
- Desktop PC or Laptop with an available USB 3.0 port (backward compatible with USB 2.0, but performance may be reduced).
- Operating System: Windows 11/10 (32/64-bit).
- Note on Band Support:
- On Windows 10, this WiFi device supports 5GHz and 2.4GHz bands only.
- On Windows 11, it supports 6GHz, 5GHz, and 2.4GHz bands, provided your router also supports 6GHz.
Installation Steps:
- Locate an available USB 3.0 port on your desktop or laptop. USB 3.0 ports are typically blue internally.
- Carefully insert the Teday AX5400 USB WiFi Adapter into the USB port. Ensure it is fully seated.
- The operating system (Windows 10 or 11) should automatically detect and install the necessary drivers. This process may take a few moments.
- Once the installation is complete, a notification may appear, or the network icon in your system tray will indicate that wireless networks are available.

5. Operating Instructions
After successful installation, you can connect to a wireless network.
Connecting to a WiFi Network:
- Click on the network icon (usually a WiFi symbol) in the system tray on your Windows taskbar.
- A list of available wireless networks will appear.
- Select your desired WiFi network from the list.
- Click 'Connect'. If prompted, enter the network security key (password).
- Once connected, the network icon will change to indicate a successful connection.
Understanding Tri-Band Connectivity:
Your adapter supports 2.4GHz, 5GHz, and 6GHz bands. Each band offers different characteristics:
- 2.4GHz: Offers wider coverage and better penetration through walls, but with lower speeds and more interference from other devices. Ideal for general browsing and devices further from the router.
- 5GHz: Provides faster speeds and less interference, but with a shorter range and poorer wall penetration. Ideal for streaming, gaming, and devices closer to the router.
- 6GHz (WiFi 6E): The newest band, offering the fastest speeds and lowest latency with minimal interference. Requires a WiFi 6E compatible router and Windows 11. Best for high-bandwidth applications like VR, 8K streaming, and competitive gaming.
Your system will typically choose the best available band automatically. For optimal performance, ensure your router is configured to broadcast on the desired bands.
6. Maintenance
To ensure the longevity and optimal performance of your Teday AX5400 WiFi Adapter, follow these simple maintenance guidelines:
- Keep Clean: Gently wipe the adapter with a soft, dry cloth to remove dust. Avoid using liquid cleaners or solvents.
- Proper Storage: When not in use, store the adapter in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Physical Damage: Do not drop, bend, or apply excessive force to the adapter. Ensure it is not obstructed when plugged into a USB port.
- Heat Dissipation: The adapter is designed with enhanced heat dissipation. Ensure adequate airflow around the device when in use to prevent overheating.

7. Troubleshooting
If you encounter issues with your Teday AX5400 WiFi Adapter, refer to the following common problems and solutions:
Common Issues and Solutions:
- Adapter Not Recognized / Frequent Disconnections:
- Solution: Try unplugging the adapter from the USB port and plugging it back in. Test different USB ports on your computer. Sometimes, a full computer restart can resolve recognition issues. Ensure your computer's USB drivers are up to date.
- Cannot Connect to WiFi Network:
- Solution: Double-check the WiFi password. Ensure your router is powered on and broadcasting a signal. Try restarting your router. Verify that your operating system (Windows 10/11) is up to date.
- Slow Speeds / Poor Signal:
- Solution: Ensure the adapter is plugged into a USB 3.0 port for optimal speed. Move closer to your wireless router. Minimize physical obstructions (walls, large furniture) between the adapter and the router. If possible, switch to the 5GHz or 6GHz band for faster speeds and less interference.
- 6GHz Band Not Available (on Windows 11):
- Solution: Confirm that your wireless router supports WiFi 6E and is broadcasting a 6GHz signal. Ensure your Windows 11 installation is fully updated.
