Corechips RD9700 (QTS1081B) USB to Ethernet LAN Adapter Driver

Drivers for the Corechips RD9700 USB to Ethernet adapter can be download below. The latest version that we have is 1.00.0906.0 and this covers Windows 11 all the way back to Windows XP on both x64 and x86 architecture. Installing the correct drivers is important so the adapter can give the full speed of 100Mbps. Please note this is a USB 2.0+ device and though this device will appear on a USB 1.1 port it will not be able to give the 100Mbps speed as USB 1.1 is a slow port that isn’t designed for these speeds.
