(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
: A common frustration is that Windows 11 may recognize the device as a CD-ROM drive
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.
: 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
