While there are ways to transform your laptop or desktop with a wireless connection into a router, the procedures are usually not for the common user.
Now there is a software application that only takes minutes and few clicks to turn your Windows 7 WiFi - enable laptop into a wireless router.
The software is called Connectify and you can find out more about it here:
Connectify works by taking advantage of Windows 7's native Virtual WiFi Technology.
This is the technology that makes it possible for Windows 7 to share it's WiFi connection with other WiFi devices.
This also means Connectify will not work on Windows Vista and older Windows versions.
