Review: VK-QF9700 Driver on Windows 11

Overall Rating: ⭐⭐⭐ (3/5) – Works, but requires manual effort.

Performance Expectations on Windows 11

Do not expect miracles. The VK-QF9700 is a USB 1.1/2.0 design from the early 2000s.

| Metric | Value | |--------|-------| | Max throughput | ~90-95 Mbps (real-world) | | CPU usage | Moderate (5-15% on a modern CPU) | | Latency | 1-2 ms higher than a built-in NIC | | Wake-on-LAN | Not supported |

If you need Gigabit speeds, replace the adapter. If you just need a temporary Ethernet connection for a legacy device, this driver fix works fine. vk-qf9700 driver windows 11

The Ultimate Guide to the VK-QF9700 Driver for Windows 11: Installation, Fixes, and Compatibility

Struggling to get your USB 2.0 to Fast Ethernet adapter working after upgrading to Windows 11? You are not alone.

The VK-QF9700 is one of the most widely cloned chipset identifiers in the networking world. Found in countless inexpensive USB-to-Ethernet adapters (often branded as "RdLink," "Cable Matters," or generic "USB 2.0 to RJ45"), this chipset has been a reliable workhorse for Windows 7, 8, and 10. However, with the release of Windows 11, Microsoft introduced stricter driver signing policies and a revamped network stack.

If your adapter shows up as "Unknown Device," "VK-QF9700," or "USB\VID_0FE6&PID_9700" in Device Manager, this guide will walk you through exactly how to get it running smoothly on Windows 11—permanently. Review: VK-QF9700 Driver on Windows 11 Overall Rating:

Step 1: Download the Correct Driver

Do not use random "driver updater" software. Use the verified MosChip/Davicom driver package.

Safe source: You can extract the driver from the official Linux kernel source (ironically) or use the last known working Microsoft catalog driver. For practical purposes, we recommend the DM9601 driver version 2.0.0.108 (dated 2015).

Note: We cannot host the file here, but search for "DM9601 driver Windows 10" on a trusted repository like Station-Drivers or the official MosChip archive (legacy section). The Ultimate Guide to the VK-QF9700 Driver for

Common Issues and Fixes for Windows 11

The Windows 11 Problem

Microsoft significantly tightened driver security in Windows 11 (and Windows 10 1709+). The last official driver for the QF9700 was written for Windows 7 (x86/x64). That driver is not digitally signed for modern Windows kernel requirements.

If you plug in the adapter:

Windows will install a default "USB 10/100 Ethernet adapter" but show Code 52 or Code 31 in Device Manager.
The adapter will appear, but remain in a "Not started" or "Invalid signature" state.
Result: No link light, no network connectivity.

Performance

| Aspect | Verdict | |--------|---------| | Max speed | 94–96 Mbps (limited by USB 2.0 & 100Mbps PHY) | | Latency | Acceptable for browsing, email, light gaming | | CPU usage | Very low | | Wake-on-LAN | Not supported on most clones | | Hot unplug / replug | Works if driver is correct |

Real-world test: Downloading a 10GB file took ~17 minutes at 80 Mbps average. No disconnections. Works fine for Zoom/Teams.

7) Rollback or remove

To rollback: Device Manager → Properties → Driver tab → Roll Back Driver (if available).
To fully remove: Uninstall device, delete driver package from Driver Store (advanced), or use vendor uninstaller.
