How to share by ad hoc on windows 7

An ad hoc network is a temporary connection between computers and devices used for a specific purpose, such as sharing documents during a meeting or playing multiplayer computer games. You can also temporarily share an Internet connection with other people on your ad hoc network, so those people don’t have to set up their own Internet connections. Ad hoc networks can only be wireless, so you must have a wireless network adapter installed in your computer to set up or join an ad hoc network.

1. Open Network and Sharing Center by clicking the Start button , and then clicking Control Panel. In the search box, type network, and then click Network and Sharing Center.
2. Click Set up a new connection or network.
3. Click Set up a wireless ad hoc (computer-to-computer) network, click Next, and then follow the steps in the wizard.
