The VIA Networking Technologies USB Wireless LAN Adapter is a device that allows your computer to connect to wireless networks using a USB interface. VIA Networking Technologies (now part of VIA Technologies) manufactures chipsets for networking hardware, including wireless LAN adapters. These adapters are used for Wi-Fi connections in systems that may not have built-in wireless capabilities or where users prefer external devices for wireless networking.

The Windows driver for this adapter is a piece of software that allows the operating system to communicate with the hardware (the USB wireless adapter) and enables the wireless functionality (such as scanning for networks, connecting to them, and transferring data).
