Virtual Wi-Fi in Microsoft Windows 7

Virtual Wi-Fi was formerly a project at Microsoft Research to study an interesting question: How can your computer be used to connect to multiple wireless networks at the same time? After years of work, Virtual Wi-Fi is now part of the Windows 7 operating system. It means your PC many now be able to connect to two different Wi-Fi networks simultaneously without any additional hardware required. Besides upgrading to Windows 7, you may also need a driver update for the wireless network adapter to use Virtual Wi-Fi.
