Virtual WiFi features for Windows 7

WiFi technology has changed the use of many computer users, but over the years, in addition to the speed of the increase in coverage and increase the security, wireless technology has not been much development. Since 2002, however, Microsoft Research has been working on a virtualized WiFi adapter that receives almost all wireless signals through a single hardware. Now, this virtual WiFi technology has been integrated into the Microsoft Windows 7 Network Foundation section.

In essence, virtual WiFi works very much like a virtualized operating system, sharing limited hardware resources transparently for multiple operating systems. Virtual WiFi abbreviation Vwifi is a software layer application for virtual multiple wireless adapters that allows each virtual adapter to connect to a wireless network and ensure that adapters can support multiple wireless LANs at the same time.

The feature is already integrated in Windows 7, according to the Long Zheng Blog. The reason this feature has long been uncovered is that the driver supports problem issues. This feature is not working properly because there are no suitable drivers. It is reported that as long as the WiFi hardware manufacturers recompile their hardware Windows 7 driver, then can provide the virtual WiFi function under Windows 7. However, the prerequisite is that this WLAN driver needs to be certified by Microsoft Windows 7.

Virtual WiFi Working principle

If all goes well, this feature will be automatically exposed in the near future. On Windows 7, the operating system installs a virtual device that directly hosts the wireless network features of the current WiFi network card, which can be displayed as "Wireless network Connection 2" in the Network connection menu, with the device name "Microsoft Virtual Wireless Mini Adapter".
