Zero Configuration
This section describes the operation of the Atheros Client Utility (ACU) and Windows
XP Wireless Configuration Service (WZCS).
Wireless Network Configuration
The Windows WZCS is a service that manages the wireless connection in a largely
dynamic way. Only minimal connection information must be identified and configured.
To set Zero Configuration on Windows XP, take the following steps:
1. In Windows XP, open the Wireless Network Configuration Properties dialog box.
2. Select the check box “Use Windows to configure my wireless network settings” to set
Zero Configuration.
When this check box is selected, Windows XP takes control of these settings for all
configuration profiles:
• SSID
• Security keys
• Ad hoc settings
Note that Windows XP takes control of these settings for all configuration profiles, thus users can
not ( create new profiles with different settings while using Windows Zero Configuration.
The Zero Configuration settings override all configuration profiles, even when you select
other options. However, the ACU does still control the following settings when Zero
Configuration is set:
• Power settings
• Active/Passive scanning (where applicable)
• Transmit power
• Wireless band
• Short/Long preamble (802.11b)
When Zero Configuration is in use, a pop-up message is displayed on the ACU when
you attempt to create or edit a configuration profile from the Profile Management tab of
the ACU.
