Introduction

The Atheros 802.11n Client Adapter supports legacy 802.11bg and draft 802.11n 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 4.0 (with Service Pack 6)

Profile Management

Configure the wireless network adapter (wireless card) from the Profile Management tab of the Atheros Client Utility.

Add a profile Edit a profile Import a Profile Export a Profile

The wireless network adapter works in either infrastructure mode (which uses an access point) or ad hoc mode (a group of stations participating in the wireless LAN).

Order profiles Switch to a different profile Remove a profile Connect to a Different

Network

Create or Modify a Configuration Profile

To add a new configuration profile, click New on the Profile Management tab. To modify a configuration profile, select the configuration from the Profile list and click the Modify button.

The Profile Management dialog box displays the General tab. In profile management:

Edit the General tab. Edit the Security tab. Edit the Advanced tab.

To configure a profile for ad hoc or access point (infrastructure) mode, edit the Network Type field on the

Advanced tab.

Remove

Remove a Configuration Profile

1. Go to the Profile Management tab.

Select the profile to remove from the list of configuration profiles.

Click the Remove button.

Auto Profile Selection Management

Including a profile in the auto selection feature allows the wireless adapter to automatically select that profile from the list of profiles and use it to connect to the network.

Including a profile in auto profile selection:

1. On the Profile Management tab, click the Order Profiles button.

2. The Auto Profile Selection Management window appears, with a list of all created

profiles in the Available Profiles box.

3. Highlight the profiles to add to auto profile selection, then click Add. The profiles

appear in the Auto Selected Profiles box.

Ordering the auto selected profiles:

1. Highlight a profile in the Auto Selected Profiles box.

2. Click Move Up, Move Down, or Remove as appropriate. The first profile in the Auto

Selected Profiles box has highest priority, and the last profile has lowest priority.

3. Click OK.

4. Check the Auto Select Profiles box.

5. Save the modified configuration file.

When auto profile selection is enabled by checking Auto Select Profiles on the Profile Management tab, the client adapter scans for an available network. The profile with the highest priority and the same SSID as one of the found networks is the one that is used to connect to the network. If the connection fails, the client adapter tries the next highest priority profile that matches the SSID, and so on.

With auto profile selection enabled, the wireless adapter scans for available networks. The highest priority profile with the same SSID as a found network is used to connect to the network. On a failed connection, the client adapter tries with the next highest priority profile.

Specifies the network as either infrastructure or ad hoc.

Specifies the preamble setting in 802.11b. The default setting is Short &

Long (access point mode), which allows both short and long headers in

the 802.11b frames. The adapter can only use short radio headers if the access point supports and uses them. Set to Long Only to override allowing short frames.

Select the mode the wireless adapter uses to authenticate to an AP:

Auto causes the adapter to attempt authentication using shared, but

switches it to open authentication if shared fails.

Open enables an adapter to attempt authentication regardless of its

WEP settings. It will only associate with the access point if the WEP keys on both the adapter and the access point match.

Shared only allows the adapter to associate with access points that

have the same WEP key.

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.

Atheros Communications, Inc. • 17 COMPANY CONFIDENTIAL March 2006

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.

Check the Status Information or Diagnostics

The Atheros client utility includes a number of tools to display current diagnostics and status information.

This feature prevents attacks on WEP in which someone catches encrypted packets and uses their initialization vector (IV) to decipher the WEP key. TKIP removes the predictability to protect both unicast and broadcast WEP keys.

EAP authentication provides dynamic unicast WEP keys for wireless adapters, but uses static broadcast keys. In broadcast WEP key rotation, the access point supplies a dynamic broadcast WEP key and changes it at intervals.
