Your computer may employ the Intel® Next-Gen Wireless-N technology* compliant with the IEEE 802.11a/b/g standard and the IEEE 802.11n draft standard. *Employed only on models that support the IEEE 802.11n draft standard. Wireless LAN devices using the 2.4 GHz bandwidth and the ones using the 5 GHz bandwidth cannot communicate with each other because the frequencies are different. The 2.4 GHz bandwidth used by wireless LAN compatible devices is also used by other various devices. Although technologies to minimize interference from other devices that use the same bandwidth are employed on wireless LAN compatible devices, such interference may cause lower communication speed, narrower communication range, or broken wireless connections. The communication speed varies depending on the distance between communication devices, existence of obstacles between such devices, the device configuration, the radio conditions, and the software in use. In addition, communications may be cut off depending on the radio conditions. The communication range varies depending on the actual distance between communication devices, existence of obstacles between such devices, the radio conditions, the ambient environment that includes existence of walls and materials of such walls, and the software in use. 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. 7676nNUsing Your VAIO Computer Communicating without an Access Point (Ad-hoc) An ad-hoc network is a network in which a LAN is created only by the wireless devices themselves, with no other central controller or access point. Each device communicates directly with other devices in the network. You can set up an ad-hoc network easily at home. . If the wireless connection is initiated by the VAIO computer, channel 11 will be selected by default. . If the wireless connection is initiated by peer wireless LAN equipment, the wireless LAN communication will make use of the channel selected by the peer wireless LAN equipment. 7777nNUsing Your VAIO Computer To communicate without an access point (ad-hoc) ! 1 The IEEE 802.11n draft standard, using the 2.4 or 5 GHz bandwidth, is not available on ad-hoc networks. Turn on the WIRELESS or WIRELESS LAN switch. The Wireless LAN indicator lights up. 2 Double-click ( / ) on the taskbar to display the Wireless Device Switch window. 3 Select your desired wireless option(s) and click OK. 4 Click Start and Control Panel. 5 Click View network status and tasks under Network and Internet. 6 Click Set up a connection or network on the left pane.
