Sometimes there are places where no WiFi connection is available, only a wired internet connection.
You would like to use your smart phone/tablet to connect to the internet, but your smart phone/tablet only supports WiFi.
You have your Windows 7 powered notebook/computer connected to the wired internet and would like to share the internet connection with your smart phone/tablet by using the built-in WiFi adapter (or WLAN USB Stick).
Guess what, it’s possible! Windows 7 has a built-in functionality to create a Virtual WiFi Network.
