3. Setup Instructions

1. Insert the Adapter: Plug the Nineplus USB WiFi 6 Adapter into an available USB 3.0 port on your desktop PC or laptop. For optimal performance, use a USB 3.0 port (often identified by a blue interior).
2. Automatic Driver Installation (Windows 11/10): For Windows 11 and Windows 10 operating systems, the system will typically detect the adapter and automatically install the necessary drivers. Wait for the installation process to complete. A notification will usually appear once the device is ready for use.
3. Manual Driver Installation (If Needed): If the driver does not install automatically, or if you encounter issues, use the included USB Flash Driver. Insert the USB Flash Driver into an available USB port, locate the driver setup file, and follow the on-screen instructions to install the driver manually.
4. Verify Installation: After installation, check your computer's Device Manager (under 'Network adapters') to ensure the Nineplus AX1800 Wi-Fi Adapter is listed and functioning correctly.

Note: This adapter only supports Windows 11 and Windows 10. It does not support Windows 7, macOS, or other operating systems.

4. Operating Instructions

1. Connect to a Wi-Fi Network: Once the adapter is installed, click on the Wi-Fi icon in your computer's taskbar (usually in the bottom-right corner).
2. Select Your Network: A list of available Wi-Fi networks will appear. Select your desired network (SSID).
3. Enter Password: If prompted, enter the Wi-Fi password (security key) for your network.
4. Connect: Click 'Connect'. Your computer should now be connected to the Wi-Fi network using the Nineplus USB WiFi 6 Adapter.
5. Utilizing Dual Band: The adapter supports both 5GHz and 2.4GHz bands. The 5GHz band offers higher speeds and less interference, ideal for gaming and 4K streaming, but has a shorter range. The 2.4GHz band provides better range and penetration through walls, suitable for general browsing and stable connections over longer distances. Your computer will typically connect to the optimal band automatically, or you may see separate network names for each band from your router.
