Windows 7 Virtual Wifi

Windows Virtual Wifi(abbreviated to VWiFi) is a new concept of Microsoft introduced in the version Windows 7.0.

Through this a sigle LAN Card acts as two network adapters.
One acts in STA (short for "station") mode and other acts in AP (Access Point) mode.

This is achieved through the drivers (softwares of Microsoft). Each connection act as a separate layer in the driver. Through this technology each machine will act as a wifi access-point. This facility is not provided in the beta version. In the network connection section “'Wireless Network Connection 2” will be available in Windows 7.

How to configuring the VWifi in the machine


In command prompt type the command in the following format to create a new access point say “APnew”
netsh wlan set hostednetwork mode=allow ssid=APnew key=password
New Access Point can be started directly from control panel
