Before diving into the installation, it is crucial to understand what you are dealing with. The VIA Technologies VK-QF9700 is a USB 2.0 to Fast Ethernet controller chip. Unlike newer Gigabit chips (like AX88179 or RTL8153), the QF9700 is a slower, 10/100 Mbps controller.
Even with the driver installed, the adapter shows "No Internet" despite a link light.
Fix:
| Pros | Cons | |------|------| | Very cheap (< $10) | No native Windows 11 driver | | Works after manual install | 100Mbps only (obsolete for modern broadband) | | Low power | Signature issues on fresh Win11 installs | | No extra software | Poor labeling; fake chips exist |
There are three reliable methods to get this driver working. Follow them in order.
Many online forums mistakenly tell you to install the ASIX AX88772 driver. This is a hack because both chips simulate similar USB descriptors. Here is the truth:

(often identified as the Corechip RD9700 ) is an ultra-budget USB 2.0 to 10/100 Ethernet adapter. While advertised as a simple plug-and-play solution, using it on Windows 11
often requires manual intervention due to its aging chipset and "driver CD" emulation feature. Performance & Compatibility Review Driver Availability
: There is no official Windows 11-specific driver from a major brand. Most users rely on legacy drivers designed for Windows 7, 8, or 10. Plug-and-Play Issues

rather than a network adapter. This occurs because the device is programmed to present its own driver installer as a virtual disc, which can block the actual Ethernet functionality. Speed Limitations
: Despite the "Fast Ethernet" labeling, this chipset is limited by its USB 2.0 interface. Real-world speeds often struggle to hit the full 100Mbps, typically peaking much lower due to the low-cost internal hardware. Before diving into the installation, it is crucial
: Users frequently report connection drops or "Cable Unplugged" errors on modern Windows versions, often caused by power management settings that turn the device off to save energy. Installation Guide for Windows 11
