You may have heard that Microsoft developed such a thing as Virtual WiFi and planned to enable its support in Windows 7. Something didn’t grow there and didn’t officially get into the new OS.
However, the guys from Nomadio claim that some of the code still remained in the final version. And part of this was enough to create a program that gives the full functionality of the virtual hotspot. As expected, the appearance of the program was not long in coming. Connectify is a free program that turns any Windows 7 computer into virtual Wi-Fi hotspot.
