Wireless Zero Configuration Service (Windows XP)

Windows XP offers the Wireless Zero Configuration Service to support 802.11b and 802.11g wireless networking.This service automatically polls the area for available wireless access points. If an available wireless access point is found,Windows attempts to connect to the access point. If no available wireless access points are found, you must manually add the access points.

Note:The Wireless Zero Configuration Service and Client Manager do not function properly together. If you want to use Client Manager, you must disable the Wireless Zero Configuration Service.

Enabling the Wireless Zero Configuration Service

Select Start»Control Panel»Administrative Tools»Services to open the Services window. Select Automatic in the Startup Type field of Wireless Zero Configuration Service to enable the Wireless Zero Configuration Service.

Note:The default Startup Type value of Wireless Zero Configuration Service is Automatic.

Disabling the Wireless Zero Configuration Service

Select Start»Control Panel»Administrative Tools»Services to open the Services window. Select Disabled in the Startup Type field of Wireless Zero Configuration Service to disable the Wireless Zero Configuration Service.

Regulatory Information A

Wireless communication is often subject to local radio regulations. Although AirStation wireless networking products have been designed for operation in the license-free 2.4 GHz band, local radio regulations may impose limitations on the use of wireless communication equipment.

•The range of wireless devices can be affected by metal surfaces, solid high-density materials and obstacles in the signal path.

•In Open Office environments, clients can “see” each other, i.e. there are no physical obstructions between them.

•In Semi-open Office environments, work space is separated by room dividers; client cards are at desktop level.

•In Closed Office environments, workspace is separated by floor-to-ceiling brick walls.

NOTE: The range values listed in Table “Radio Characteristics” are typical distances as measured at Buffalo Technology AirStation laboratories.These values are provided for your guidance but may vary according to the actual radio conditions at the location where the AirStation product is installed.

The range of the wireless signal is related to the Transmit Rate of the wireless communication. Communications at a lower Transmit range may travel longer distances.
