The Wireless Hosted Network is new interesting feature supported on Windows 7 and up. As described in documentation, this feature implements two major functions:
- The virtualization of a physical wireless adapter into more than one virtual wireless adapter sometimes referred to as Virtual Wi-Fi.
- A software-based wireless access point (AP) sometimes referred to as a SoftAP that uses a designated virtual wireless adapter.
So, if you want to share your internet connection from your laptop (for example, if you have mobile 3G modem in your laptop and you want to share some data with your friends near you ;), you already have everything required on your laptop (in case if your HW allow it). Example:
netsh wlan set hostednetwork mode=allow ssid="MyHostpot" key="usedpassword" keyUsage=persistent netsh wlan start hostednetwork
