To send data from one computer to another, you either need wires to connect them, or you need to purchase a router so that you can transfer data wirelessly.

However, if your laptop or desktop computer has a wireless network card then it could be connected to another PC in your house, provided the other one has wireless capabilities too. And you don�t need a router to establish this connection. This is known as an ad-hoc network connection.

Here are the steps to setup an ad-hoc home wireless network in Windows Vista.

1. Go to Control panel and click on Network and Sharing center icon.

2. On the left side under Tasks, click on �Set up a connection or network� option.

3. Now click on  �Set up a wireless as hoc (computer to computer) network�.

4. Click on Next button.

5. Now give a name to your network. The default security type should be WPA2-Personal. Let it be like that  because WPA2 is much better than WEP when it comes to wireless network security. Choose a security passphrase, click on save network if you intend to use this network again, and hit next.

Your network will be build successfully. Now you can connect any Wi-Fi enabled device to your computer. If you search for available wireless networks, you will find a newly built network  (�My network� in this case) on your device.

In this way you can access and transfer data between your wi-fi enabled phone, printer, laptop and computer. A simple and easy method to setup an ad-hoc network
