If you have two wireless computers, you can set up a connection between the two systems. During the set up process, you need to specify a network security type to keep the connection safe and a passphrase (a security key) to provide secure access. You can set the security type to Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), or 802.1X authentication. WEP is a widely used network security type that uses an encrypted security key to provide a secure wireless environment. WPA improves on the security of WEP and checks to make sure the security key has not been modified. 802.1x is a sever authentication security type typically used for workplace networks. If you have a USB flash drive, you can save wireless network settings to the drive and use it to quickly add computers to your network.
Set Up a Wireless Connection to Another Computer
Click the Start button, and then click Connect To.
Click Set up a connection or network.
In the left pane, click Set up a wireless ad hoc (computer-to-computer) network, and then click Next to continue.
Type a passphrase (point to the box and use the ScreenTip for help), and then write it down so you can use it the first time that people connect to this network.
