Using the WiFi protected access (WPA)
WPA is a wireless security enhancement that allows you to transfer data in a highly secure way*.
To use WPA on your notebook, proceed as follows:
1 Turn on the Wireless LAN switch.
2 Right-click the network icon on the taskbar displaying Wireless Network Connection.
3 Select View available network connections.
The Wireless Network Properties dialog box appears.
4 Select the wireless network to which you want to connect.
5 Fill in the Network key.
The network key should be at least 8 characters long. You can choose whatever you want.
6 Fill in exactly the same Network key again, for confirmation.
7 Click Connect.
The connection is established.
* For more information on the access point, please refer to its manual.
In Ad-hoc mode, WPA security cannot be used (specifications in the standard itself).
In France, only certain channels are legally allowed when using WLAN outdoors. For more information, see the Wireless LAN Regulations.
