The Network Driver Interface Specification (NDIS) library abstracts the network hardware from network drivers. Then follow the onscreen instructions to update your driver. Click Search automatically for updated driver software. Select your NDIS device, right-click on it, and click Update driver in the context menu. In the Device Manager window, double-click Network adapters to expand its drop-down list. What does WAN Miniport mean?Ī wide area network mini port (WAN mini port) is a driver that permits alternative connection methods in Windows XP and later version of Windows such as point-to-point protocol over Ethernet (PPoE) and wireless networking making WAN setup possible. WAN Miniport is a driver that allows alternative connection methods in Windows XP and later versions, including connecting to the Internet through a point-to-point protocol over Ethernet (PPoE) as well as wireless networking, making WAN connections possible. Also, the driver might deactivate a port for application-specific reasons. After a miniport driver successfully activates a port, the driver must deactivate the port before it can free the port. To deactivate NDIS ports, a miniport driver sends a port deactivation Plug and Play (PnP) event to NDIS. NDIS (Network Driver Interface Specification) is a Windows specification for how communication protocol programs (such as TCP/IP) and network device driver should communicate with each other. Interfacing with higher-level drivers, such as filter drivers, intermediate drivers, and protocol drivers. What is NDIS miniport driver?Īn NDIS miniport driver has two basic functions: Managing a network interface card (NIC), including sending and receiving data through the NIC. Protocol drivers are the components that interprets the settings of linked tags, converts into data packets, write the packet on the communication port, takes the response received by communication port, decodes the response and update the tags.
