Check Device Manager for yellow triangles and search for the specific error code (e.g., Code 10, 31, 52) to refine your troubleshooting further.
Once installed, users must also manage their expectations regarding performance. The VK-QF9700 is a Fast Ethernet adapter, meaning it is capped at 100 Mbps. In a Windows 11 environment, which is often optimized for Gigabit speeds and high-bandwidth cloud computing, the adapter becomes a bottleneck. While it successfully provides a stable wired connection—essential for large file transfers or stable remote desktop sessions where Wi-Fi is unreliable—it cannot utilize the full potential of modern networking infrastructure. Furthermore, because the drivers are likely legacy code wrapped for compatibility, users may experience higher CPU utilization during heavy network loads compared to modern, native USB-C Ethernet controllers. vk-qf9700 driver windows 11
Connect the adapter to your Windows 11 PC while connected to the internet. Windows 11 often identifies the hardware ID ( USB\VID_0FE6&PID_9700 ) and downloads a compatible driver automatically through the Windows Update service. Go to Settings > Windows Update .
