Once upon a time we wanted to make a virtual router. We wanted every user to use all functionality of your computer.
There was also a desire to create intuitive and simple interface to some complex functionality as Windows.
And we did it!
We have created a fully featured virtual router right inside your PC!
You can turn your computer into a real WIFI hotspot with Virtual WIFI!
More recently, you have seen this feature only in the mobile phone (tethering), but now your computer can do that too!
Also you can share the Internet via Wi-Fi with any other PC or mobile device.
