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 or Move Down 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.

      Power Save Specify:
           Mode
                    • Maximum mode causes the access point to buffer incoming
                          messages for the wireless adapter. The adapter up 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 (access point mode) or ad hoc.
          802.11b Specifies the preamble setting in 802.11b. The default setting is Short &
         Preamble Long (AP 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.
   Wireless Mode 2.4 GHz 54 Mbps, 2.4 GHz 11 Mbps, or Super
                 b/g operation in an access point network. The wireless adapter must match
                 the wireless mode of the access point it associates to.
 Wireless Mode 2.4 GHz 54/11 Mbps to start
when Starting an an ad hoc network if no matching network name is found after scanning all
Ad Hoc Network available modes.

                    This mode also allows selection of the channel the wireless adapter uses.
                    The channels available depend on the regulatory domain. If the adapter
                    finds no other ad hoc adapters, this selection specifies the which channel
                    with the adapter starts the ad hoc network with.

                    The wireless adapter must match the wireless mode and channel of the
                    clients it associates to.

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 an NT 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

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 Station Configuration tab of the ACU.

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
        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.
                     d. A few files matching these criteria are possible, if previous drivers have
                        not been removed properly.
                     e. 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.
