Introduction The Atheros 802.11n Adapter supports 802.11bg operation. The card uses the Atheros Client Utility (ACU) which is a user-mode utility designed to edit and add profiles for selected Atheros network interface adapters. System Requirements • • Laptop/ PC containing: • 32-bit PCI Express Bus • 32 MB memory or greater • 300 MHz processor or higher Microsoft Windows 2000, Windows Millennium Edition, Windows 98 Second Edition, Windows XP, or Windows NT 4.
Remove a Configuration Profile 1. Go to the Profile Management tab. 2. Select the profile to remove from the list of configuration profiles. 3. Click the Remove button.

Using EAP-TLS Security To use EAP-TLS security In the Atheros Client Utility, access the Security tab in the Profile Management window. 1. On the Security tab, choose the WPA radio button. OR: On the Security tab, choose the 802.1x radio button. 2. Choose EAP-TLS from the drop-down menu.
• Leave the server name field blank for the client to accept a certificate from any server with a certificate signed by the authority listed in the Network Certificate Authority drop-down list. (recommended) • Enter the domain name of the server from which the client will accept a certificate. • Change the login name if needed. 5. Click OK. 6. Enable the profile.
Using PEAP-MSCHAP V2 Security To use PEAP-MSCHAP V2 security In the Atheros Client Utility, access the Security tab in the Profile Management window. 1. On the Security tab, choose the WPA radio button. OR: On the Security tab, choose the 802.1x radio button. 2. Choose PEAP (EAP-MSCHAP V2) from the drop-down menu. To use PEAP (EAP-MSCHAP V2) security, the server must have WPA-PEAP certificates, and the server properties must already be set. Check with the IT manager. 1. Click the Configure button. 2.
Using LEAP Security To use security In the Atheros Client Utility, access the Security tab in the Profile Management window. LEAP security requires that all infrastructure devices (e.g. access points and servers) are configured for LEAP authentication. Check with the IT manager. Configuring LEAP • • On the Security tab, choose the WPA radio button. Choose WPA-LEAP from the drop-down menu. OR: On the Security tab, choose the 802.1x radio button. Choose LEAP from the drop-down menu. 1.
Pre-Shared Encryption Keys Defining pre-shared encryption keys: 1. Click the Pre-Shared Key (Static WEP) radio button on the Security tab. 2. Click the Configure button. 3. Fill in the fields in the Define Pre-Shared Keys dialog box: Key Entry Determines the entry method for an encryption key: hexadecimal (0-9, A-F), or ASCII text (all keyboard characters except spaces). Encryption Selects the default encryption keys used.
Using WPA Passphrase Security To use WPA Passphrase security In the Atheros Client Utility, access the Security tab in the Profile Management window. 1. 2. 3. 4. On the Security tab, choose the WPA Passphrase radio button. Click on the Configure button. Fill in the WPA Passphrase. Click OK. Zero Configuration This section describes the operation of the Atheros Client Utility (ACU) and Windows XP Wireless Configuration Service (WZCS).
To turn Zero Configuration off on Windows XP, take the following steps: 1. In Windows XP, open the Wireless Network Configuration Properties dialog box. 2. Clear the check box “Use Windows to configure my wireless network settings” to set Zero Configuration. When this check box is cleared, all profile settings are controlled by the configuration profile, which is set up from the ACU Profile Management tab.
