Yeah you heard right. You can turn your ordinary laptop running Windows 7 into a Wi-Fi hotspot thanks to an undocumented Windows 7 feature called Virtual Wi-Fi. The feature, which had been under development by Microsoft Research allows you to split your wireless card into several virtual adapters, thereby turning your notebook into a wireless hotspot.
You can connect all sorts of Wi-Fi enabled devices and share internet connection among them. And if you are wondering, then no, it doesnâ€™t setup an AdHoc network. This is regular access point, encrypted with WPA2 encryption.
Interestingly, you can still use your computerâ€™s Wi-Fi like you do regularly while it is functioning like a hotspot, i.e. connect to other Wi-Fi connections etc. For more information, regarding the software or technology, take a look at the FAQS section on the official website.
You can participate in the public beta and download Connectify to your PC.
