Your Network name appears in the Preferred networks. 15 Select the Computer-to-computer (ad hoc) networks only option button. Your computer is ready to communicate with another computer. * If you want to communicate between two or more computers, you need to configure all these computers the exact same way. This means that you need to enter the same Network name and the same Network key on all computers as on the first computer you configure. ** Hexadecimal: A number representation using the digits 0-9, with their usual meaning, plus the letters A-F (or a-f) to represent hexadecimal digits with values of (decimal) 10 to 15. In France, only certain channels are legally allowed when using WLAN outdoors. For more information, see the Wireless LAN Regulations. An ad-hoc network does not support WPA. nN 48 Using your VAIO computer Communicating with an Access Point (infrastructure) An infrastructure network is a network that extends an existing wired local network to wireless devices by providing an Access Point, for example the Sony Access Point PCWA-A320. The Access Point bridges the wireless and wired LAN and acts as a central controller for the Wireless LAN. The Access Point coordinates transmission and reception from multiple wireless devices within a specific range. To communicate with an Access Point (infrastructure), proceed as follows: 1 2 3 4 5 Turn on the Wireless LAN switch. Right-click the network icon on the taskbar displaying the Wireless Network Connection message. Click View Available Wireless Networks. Deploying IEEE 802. 11b and IEEE 802. 11g products on the same wireless network may reduce the communication speed due to radio interference. Taking this into consideration, the IEEE 802. 11g products are designed to reduce the communication speed to ensure communications with IEEE 802. 11b products. When the communication speed is not as fast as expected, changing the wireless channel on the access point may increase the communication speed. nN 52 Using your VAIO computer Troubleshooting Wireless LAN I cannot use the Wireless LAN functionality Check if the Wireless LAN switch is turned on. The Wireless LAN Access Point and your computer cannot communicate Check if the Wireless LAN switch is turned on. Check if the power of the Access Point is turned on. Check if the Access Point is displayed in the Available networks window. To check this, click Start and then Control Panel. Click Network and Internet Connections. Right-click the Wireless Network Connection icon and select Properties. Check if the Access Point is displayed in Available networks. Connection availability is affected by distance and obstructions. You may need to move your computer away from obstructions or neared to any Access Point you may be using. nN 53 Using your VAIO computer The data transfer speed is slow The maximum communication speed can vary depending on the obstacles or the distance between the communication devices, the radio waves, the operating system or the software you use. [. . . ] If, after fully charging the battery pack, the battery power is still low, the battery pack may be reaching the end of its life and should be replaced. You do not need to discharge the battery before recharging. If you have not used the battery pack for a considerable amount of time, recharge the battery.
