[. . . ] You can communicate without an Access Point, this means that you can communicate between a limited number of computers (ad-hoc), or you can communicate through an Access Point, which allows you to create a full infrastructure network (infrastructure).
* Depending on your model.
In some countries, using WLAN products may be restricted by the local regulations (e. g. Therefore, before activating the WLAN functionality, read the Wireless LAN Regulation leaflet carefully. Channel selection is explained further in this manual (see Wireless LAN channel selection (page 43)). WLAN uses the IEEE 802. 11b/g standard, which specifies the used technology. The standard includes the encryption method: Wired Equivalent Privacy (WEP), which is a security protocol and WiFi Protected Access (WPA - Proposed jointly by the IEEE and Wi-Fi Alliance, WiFi Protected Access is a specification of standards based, interoperable security enhancements that increase the level of data protection and access control for existing WiFi networks. WPA has been designed to be forward compatible with the IEEE 802. 11i specification. It utilizes the enhanced data encryption TKIP (Temporal Key Integrity Protocol) in addition to user authentication using 802. 1X and EAP (Extensible Authentication Protocol)). Data encryption protects the vulnerable wireless link between clients and Access Points. Besides that, there are other typical LAN security mechanisms to ensure privacy, such as: password protection, end-to-end encryption, virtual private networks, and authentication. Wireless LAN devices using the IEEE 802. 11a standard and the ones using the IEEE 802. 11b or g standard cannot communicate because the frequencies are different. Wireless LAN devices using the IEEE 802. 11g standard can only communicate with a device using the IEEE 802. 11b standard, not with the IEEE 802. 11a standard. ATT: In France, outdoors, Wireless LAN connections are only allowed on certain channels. If the Wireless connection is initiated by a peer Wireless LAN equipment, the Wireless LAN communication will make use of the channel selected by the peer Wireless LAN equipment.

Troubleshooting Wireless LAN
I cannot use the Wireless LAN function
Check if the Wireless 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 Access Point is displayed in the Available networks window. Right-click the Wireless Network Connection icon and select Properties. You may need to move your computer away from obstructions or neared to any Access Point you may be using.
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. Remove the obstacle or make the distance between the Access Point and your machine smaller. It is possible that your Access Point communicates at the same time with another Access Point. If several computers communicate with the same Access Point, the concentration may be too high. Wait a few minutes and try to access again.

If a Wireless LAN device using the IEEE 802. 11g standard communicates with a device using the IEEE 802. 11b standard, then it is normal that the speed reduces.
I cannot access the Internet
Check the settings of the Access Point. Make the distance between the Access Point and your machine smaller.

Using power saving modes
When you use a battery as the source of power for your computer, you can take advantage of power management settings to conserve battery life. In addition to the normal operating mode, which allows you to turn off specific devices, your computer has two distinct power saving modes: Standby and Hibernate. [. . . ] The computer uses high-frequency radio signals and may cause interference to radio or TV reception. Should this occur, relocate the computer a suitable distance away from the set. Use only specified peripheral equipment and interface cables; otherwise, problems may occur. If the computer is brought directly from a cold location to a warm one, moisture may condense inside your computer. [. . . ]
