An NDIS driver is a type of device driver on your computer that manages your machine's networking adapters. This driver allows your operating system to recognize the networking devices installed in your computer, which in turn allows you to go onto wired or wireless Internet connections. Upgrading an NDIS driver involves using the native Windows device driver management utility called "Device Manager."
