Introduction
       The Atheros Client Utility (ACU) 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                     •   Order profiles
               •    Edit a profile                    •   Switch to a different profile
               •    Import a Profile                  •   Remove a profile
               •    Export a Profile                  •   Connect to a Different
                                                          Network

       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).

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.

       Note that the ACU only allows the creation of 16 configuration profiles. After the
       creation of 16 profiles, clicking the New button displays an error message. Remove an
       old profile or modify an existing profile for a new use.

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.


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.

Switching to a Different Configuration Profile
       1. To switch to a different profile, go to the Profile Management tab.
       2. Click on the profile name in the Profile List.
       3. Click the Activate button.

       The Profile List provides icons that specify the operational state for that profile. The list
       also provides icons that specify the signal strength for that profile.


Import and Export Profiles
Importing a Profile

       1. From the Profile Management tab, click the Import button. The Import Profile
          window appears.
       2. Browse to the directory where the profile is located.
       3. Highlight the profile name.
       4. Click Open. The imported profile appears in the profiles list.

Exporting a Profile

       1.   From the Profile Management tab, highlight the profile to export.
       2.   Click the Export button. The Export Profile window appears.
       3.   Browse to the directory to export the profile to.
       4.   Click Save. The profile is exported to the specified location.


TCP/IP Configuration
Configuring the TCP/IP Address for the network device:

   1. After configuring the wireless network adapter properties, open the Control Panel and
      open Network and Dial-up Connections.
   2. Find the Local Area Connection associated with the wireless network adapter. Right-
      click that connection, and click Properties.
   3. Select Internet Protocol (TCP/IP) and click Properties.
   4. Click the radio button Use the following IP address, then enter an IP address and Subnet
      mask. Assigning an IP address and Subnet mask allows stations to operate in access
      point mode (infrastructure mode) or in ad hoc mode and to have Internet access. Default
      gateway and DNS server information is also required. IP configuration information
      (DHCP to assign the IP address, gateway and DNS server IP addresses) is usually
      obtained from the corporate IT staff.
   5. Click OK to finish.

General Tab
       In the Atheros Client Utility, access the General tab by clicking New or Modify on the
       Profile Management tab. Edit the fields in the General tab to configure the configuration
       profile. Make sure to also edit the Security and Advanced tabs.

                      Profile Name Identifies the configuration profile. This name must be
                                   unique. Profile names are not case sensitive.
                       Client Name Identifies the client machine.
        Network Names (SSIDs) The IEEE 802.11 wireless network name. This field has a
                              maximum limit of 32 characters.
                              Configure up to three SSIDs (SSID1, SSID2, and SSID3).

Advanced Tab
       In the Atheros Client Utility, access the Advanced tab by clicking New or Modify on the
       Profile Management tab, then clicking the Advanced tab in Profile Management. Edit
       the fields in the Advanced tab of Profile Management to configure the profile.
           Transmit Selects the transmit power level in mW. Actual transmit power may be
         Power Level limited by hardware.
          Power Save Specify:
               Mode • Maximum mode causes the access point to buffer incoming messages
                        for the wireless adapter. The adapter periodically polls the access
                        point to see if any messages are waiting.
                     • Normal uses maximum when retrieving a large number of packets,
                        then switches back to power save mode after retrieving the packets.
                     • Off turns power saving off, thus powering up the wireless adapter
                        continuously for a short message response time.
       Network Type Specifies the network as either infrastructure or ad hoc.
                802.11b Specifies the preamble setting in 802.11b. The default setting is Short &
               Preamble 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.
       Authentication Select the mode the wireless adapter uses to authenticate to an AP:
                Mode • 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.

       •    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.

Ad Hoc Mode
       In ad hoc mode, a wireless network adapter works within an independent basic service
       set (IBSS), as illustrated here. All stations communicate directly with other stations
       without using an access point (AP).




       To connect to an ad hoc network, configure the profile for ad hoc mode. Ad Hoc
       operation may be limited by Hardware to meet regulatory requirements.

Ad Hoc Mode Profile Configuration
       To configure a profile in ad hoc mode, change the Network Type in the Profile
       Management's Advanced tab. For ad hoc mode, modify the settings:

       •   Network Name (on General Tab)

       •   Wireless Mode When Starting an Ad Hoc Network

       Make sure to also edit the General and Security tabs.


 Infrastructure (Access Point) Mode
       In infrastructure (access point (AP)) mode, the wireless network adapter participates in a
       basic service set (BSS) as a station, and communicates with the other stations through an
       AP, as illustrated here.




       To connect to an access point network, configure the profile for access point mode.

Infrastructure (Access Point) Mode Profile Configuration
       To configure a profile in infrastructure (access point) mode, change the Network Type in
       the Advanced tab. For access point mode, modify the settings:

Uninstall an Old Driver
       Uninstall an old driver before upgrading to a new NDIS driver release.

       To remove the newly installed driver from the system if the system does not have
       previously installed versions of the NDIS driver, proceed to Step 4.

       1. To remove the NDIS driver from the OS, go to Device Manager, right-click Atheros
          AR500x Wireless Network Adapter, and choose Uninstall.
       2. Click OK to uninstall the device.
       3. When the device is uninstalled from Device Manager, search for and delete the
          driver files that reside in the system.
              a. Go to the Start menu and choose Search > For Files or Folders.
              b. Enter oem*.inf in the Search for files or folders named: field, and enter
                  Atheros in the Containing text: field.
              c. Click Search Now. A few files matching these criteria are possible, if previous
                  drivers have not been removed properly.
              d. Choose the files that have been found and delete them from the system.
       4. To complete the uninstallation, remove the file ar5211.sys from the folder
          \WINNT\system32\drivers.


Additional Security Features
       These security features prevent attacks on a wireless network's WEP keys. The wireless
       adapter automatically supports each of these features, but these features must be enabled
       on the access point.

Message Integrity Check (MIC)

       MIC prevents bit-flip attacks on encrypted packets. In a bit-flip attack, someone
       intercepts an encrypted message retransmits it after some alterations. Thus the receiver
       accepts the message as legitimate. The MIC adds some bytes to each packet to protect it
       against tampering.

Temporal Key Integrity Protocol (TKIP)

       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.

Broadcast Key Rotation

       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.
