Build a Wireless LAN via Notebook (without Router)

You wanna make a wireless LAN (Wi-Fi) around your home but you doesn't have a router. Think again before you buy it, because I have a way to do that. Things that you need are:
1. A notebook with built-in Wireless LAN (I think all notebooks have it now)
2. Connectify Software, download here!

You just run it, give a name and password (optional) for your Wireless LAN, and done!
See that other people around you are happy with your network. :-)
