3.2 Driver Installation

After physical installation, you will need to install the necessary drivers for the Wi-Fi and Bluetooth functions. It is highly recommended to download the latest drivers directly from the Intel website for the AX210 chipset.

1. Download Drivers: Visit the official Intel website and search for "AX210 drivers". Download the latest Wi-Fi and Bluetooth drivers compatible with your operating system (Windows 10/11 64-bit).
2. Install Wi-Fi Driver: Run the downloaded Wi-Fi driver installer and follow the on-screen instructions.
3. Install Bluetooth Driver: Run the downloaded Bluetooth driver installer and follow the on-screen instructions.
4. Verify Installation: Open Device Manager (search for "Device Manager" in Windows search). Expand "Network adapters" and "Bluetooth". You should see "Intel(R) Wi-Fi 6E AX210 160MHz" under Network adapters and "Intel(R) Wireless Bluetooth(R)" under Bluetooth.

4. Operating Instructions

4.1 Connecting to Wi-Fi

1. Once drivers are installed, click on the Wi-Fi icon in your Windows taskbar.
2. Select your desired Wi-Fi network (2.4GHz, 5GHz, or 6GHz band).
3. Enter the network security key (password) if prompted.
4. Your computer should now be connected to the Wi-Fi network.

4.2 Bluetooth Pairing

1. Go to Windows Settings > Devices > Bluetooth & other devices.
2. Ensure Bluetooth is turned On.
3. Click "Add Bluetooth or other device" and select "Bluetooth".
4. Put your Bluetooth device into pairing mode.
5. Select your device from the list and follow any on-screen prompts to complete pairing.

5. Troubleshooting

• No Wi-Fi or Bluetooth after installation: Ensure the Bluetooth header cable is correctly connected to both the PCIe card and the motherboard's 9-pin USB header. Verify that the card is fully seated in the PCIe slot.
• "Network Controller" with a warning in Device Manager: This indicates missing or incorrect drivers. Download and install the latest Wi-Fi and Bluetooth drivers from the official Intel website for the AX210 chipset.
• Poor Wi-Fi signal or slow speeds: Adjust the position and angle of the external antennas to optimize signal reception. Ensure your router is Wi-Fi 6E compatible to fully utilize the 6GHz band.
• Compatibility Issues: This card supports Windows 10/11 (64-bit) operating systems. For 6GHz Wi-Fi, Windows 11 or a Windows 10 Dev version is required. The card is compatible with all PCIe standards, but a PCIe x1 slot is often recommended for best compatibility.
• Bluetooth not working: Confirm the Bluetooth header cable is securely connected. Check Device Manager for any issues with the Bluetooth device.
