Microsoft Research has been exploring a fascinating idea to virtualize the WiFi adapter, turning a single piece of hardware and radio into virtually (pun) unlimited adapters. It’s now uncovered Virtual WiFi technology has been baked into the Windows 7 networking foundations.
This feature will be automatically exposed: “On Windows 7 and later, the operating system installs a virtual device if a Hosted Network capable wireless adapter is present on the machine. This virtual device normally shows up in the “Network Connections Folder” as ‘Wireless Network Connection 2’ with a Device Name of ‘Microsoft Virtual WiFi Miniport adapter’ if the computer has a single wireless network adapter. This virtual device is used exclusively for performing software access point (SoftAP) connections [...]. The lifetime of this virtual device is tied to the physical wireless adapter. If the physical wireless adapter is disabled, this virtual device will be removed as well.”
