2. Package Contents
Please verify that your package contains the following items:

Note: Drivers are typically included on the device itself for easy installation or can be downloaded from the manufacturer's website.
3. Setup Instructions
Follow these steps to install and set up your Fenvi FU-AX300 Wi-Fi 6 USB Adapter:
- Insert the Adapter: Locate an available USB port on your desktop or laptop computer. Carefully insert the Fenvi FU-AX300 USB adapter into the USB port. Ensure it is fully seated.
- Driver Installation (Windows 11/10):
- For most Windows 11/10 systems, the operating system may automatically detect and install the necessary drivers. Wait a few moments for this process to complete.
- If automatic installation does not occur, or if prompted, you may need to run the driver installer. The FU-AX300 is often "driver-free" meaning the driver is stored on the device itself and can be accessed like a USB drive.
- Open "This PC" or "My Computer" and look for a new drive labeled "FENVI" or similar. Double-click to open it and run the setup executable (e.g., "setup.exe" or "install.exe").
- Follow the on-screen instructions to complete the driver installation.
- Alternatively, download the latest drivers from the official Fenvi support website if you encounter issues.
- Verify Installation: After driver installation, check your computer's Device Manager (search for "Device Manager" in Windows search) under "Network adapters" to confirm that the Fenvi FU-AX300 adapter is listed and functioning correctly.

- Access Wi-Fi Settings: Click on the Wi-Fi icon in the system tray (usually in the bottom-right corner of your screen) or navigate to Settings > Network & Internet > Wi-Fi.
- Select Network: A list of available Wi-Fi networks will appear. Select your desired network (SSID).
