You require stable gigabit speeds, Wake-on-LAN, or absolute plug-and-play simplicity. Summary Checklist ☐ Identify your adapter’s VID/PID as 0FE6:9700 ☐ Download the 64-bit DM9601 driver (version 2.0.0.108 or newer) ☐ Install via Device Manager > Have Disk ☐ Disable IPv6 and set Speed & Duplex to 100 Mbps Full ☐ Disable USB selective suspend ☐ Reboot and test with ping 8.8.8.8 vk-qf9700 driver windows 11
Microsoft did not intentionally block the VK-QF9700 in Windows 11, but they deprecated many legacy NDIS 5.1 drivers. The working driver for this chipset is actually a modified version of the driver (Davicom DM9601 USB Ethernet adapter). | Metric | Value | |--------|-------| | Max
Ensure you download the amd64 (64-bit) version of the DM9601 driver. Windows 11 no longer supports 32-bit drivers for network hardware. Issue 2: Limited connectivity / No Internet Even with the driver installed, the adapter shows "No Internet" despite a link light. Ensure you download the amd64 (64-bit) version of
