Using a WLAN

A wireless connection connects the computer to Wi-Fi networks, or WLANs. A WLAN is composed of other computers and accessories that are linked by a wireless router or a wireless access point.

NOTE: When creating a wireless connection or allowing access to users in a network, you are prompted for the root password.

Connecting to an existing WLAN

1.Be sure that the WLAN device is on.

NOTE: Refer to Getting to know your computer on page 4 for information on identifying the location of the wireless button and wireless light on your computer.

2.Click the Network Connection icon in the notification area, at the far right of the taskbar. Available wireless networks are listed under Wireless Networks.

3.Click the desired wireless network.

If the network is a security-enabled WLAN, you are prompted to enter a network security code. Type the code, and then click OK to complete the connection.

NOTE: To connect to a network that is not automatically detected, click the Network Connection icon and select Connect to Hidden Wireless Network. Enter the ESSID information, and set encryption parameters.

NOTE: If no WLANs are listed, and your network is not hidden, you are out of range of a wireless router or access point.
