So recently I was on a friend’s computer trying to troubleshoot some network issue and when I went to adjust the settings on one of the network adapters, I noticed something interesting I had not seen before: In addition to the normal WiFi network, there was also a Wireless Network Connection 2 and the adapter name was “ Microsoft Virtual WiFi Miniport Adapter“. I had never seen this before, so it made me very curious.

After some reading, I learned it’s a new feature in Windows 7 and it actually can let you do some pretty cool stuff with your wireless network card. In this article, I’ll explain what the virtual WiFi mini port adapter is and how you can use it on your Windows 7 PC. Apparently, this is a feature that is still in beta and therefore you won’t find very much official documentation on how to use it. Basically, Virtual WiFi is a technology that virtualizes your network adapter much in the same way VMWare virtualizes your entire operating system. Once virtualized, you can basically convert one physical wireless adapter into two virtual ones. This allows you to then connect one virtual network adapter to your regular wireless network and use the other virtual adapter to connect to another network such as an ad-hoc network or to create a WiFi hotspot and allow others to connect to your Windows 7 machine wirelessly like they would connect to a normal wireless access point. To play around with creating your own wireless access point, you can go about it in two ways: use the command line in Windows 7 or download a third party program that provides a nice GUI interface and some extra features.
