2. Automatic Driver Installation: For Windows 10 (32bit/64bit) and Windows 11 (64bit), the system should automatically detect the device and install the necessary drivers. A Wi-Fi signal light on the adapter will illuminate once it's ready.
3. Manual Driver Installation (If Needed): If the drivers do not install automatically, or if you experience connectivity issues, please refer to the included Quick Installation Guide for instructions on manual driver installation. Drivers can typically be found on the manufacturer's website.
4. Adjust Antennas: Rotate the two external antennas to an optimal position (e.g., 90 degrees upright or 180 degrees flat) to maximize signal reception and strength.

4. Operating Instructions

Connecting to a Wi-Fi Network:

1. Once the adapter is installed and recognized by your operating system, click on the Wi-Fi icon in your computer's taskbar (Windows).
2. A list of available Wi-Fi networks will appear. Select your desired network.
3. Enter the network password (if required) and click 'Connect'.
4. The adapter will connect to the network, and you should see a strong signal indicator.

Utilizing Tri-Band Frequencies:

The CF-972AX automatically selects the best available frequency band (2.4GHz, 5.8GHz, or 6GHz) for your connection. Ensure your Wi-Fi router also supports Wi-Fi 6E and tri-band for optimal performance.

AP Function (Wi-Fi Sharing):

The CF-972AX supports an Access Point (AP) function, allowing your computer to act as a Wi-Fi hotspot. If your computer is connected to the internet via an Ethernet cable, you can use the adapter to share that internet connection wirelessly with other devices like mobile phones, tablets, or notebooks.

1. Ensure your computer has an active internet connection (e.g., via Ethernet).
2. Access your operating system's network settings (e.g., 'Mobile hotspot' in Windows Settings).
3. Enable the mobile hotspot feature and configure the network name (SSID) and password.
4. Your CF-972AX adapter will then broadcast a Wi-Fi signal for other devices to connect to.

Antenna Adjustment:

The dual external antennas can be rotated 180 degrees. Adjust their orientation to achieve the best signal strength and coverage, especially if your computer is located far from the router or behind obstacles.
