The TP-LINK ADSL USB Remote NDIS Device driver is a software component that allows your Windows computer to recognize and communicate with an ADSL (Asymmetric Digital Subscriber Line) modem provided by TP-LINK via a USB connection. The "Remote NDIS" refers to the use of a network device interface standard that allows a device to act as a remote network interface for the computer. In this case, it facilitates the modem's role in connecting your computer to the internet through an ADSL service.
