Using your VAIO computer
Wireless LAN channel selection
In a 802.11b/g configuration, channel 1 to 13 can be used.
(a) With an access point ("Infrastructure")
❑
The channel used will be the channel selected by the access point.
!
For details on how to select the channel that will be used by the access point, refer to the documentation that came with your access point.
(b) Without access point ("Ad-Hoc")
❑
If the Wireless connection is initiated by the VAIO computer, channel 11 will be selected.
!
In France, only certain channels are legally allowed when using WLAN outdoors. For more information, see the Wireless LAN Regulations.
❑
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.

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 uses 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.
