Ad hoc wireless networks, or computer-to-computer wireless networks, are useful for Internet Connection Sharing and other direct wireless networking without needing a router. You can set up your own wi-fi network to connect two or more computers pretty simply using the steps below.
Time Required: 20 minutes
- Go to Start > then right-click on Network and select Properties (on Windows Vista/7, go to your Network and Sharing Center under Start > Control Panel > Network and Internet).
- Click on the "Set up a connection or network" option.
- Select "Set up a wireless ad-hoc network" (Vista/7 have this as "Set up a new network"). Click Next.
- Choose a name for your ad hoc network, enable encryption, and check the box to save the network. Your wireless network will then be created and your wireless adapter will start broadcasting.
- On the client computers, you should be able to locate the new network and connect to it (for more help, see How to Set Up a Wi-Fi Connection
