I have two laptops. One of them is connected to the internet via a network cable. I want to share the internet connection with the second laptop wirelessly. How can i do this without buying a wireless router?


If the laptop with the internet connection is running Windows 7, you can use Connectify to share the connection. It takes advantage of Windows 7's ability to make a wireless card appear as an access point, letting other computers connect through it without the hassle of an ad-hoc network. It will set up WAP encryption automatically, as well. I've used it before; it's very easy to set up and use.
