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
Order profiles
Switch to a different profile
Remove a profile

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 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 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 adapter tries with the next highest priority
profile.

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
Power Level

Selects the transmit power level in mW. Actual transmit power may be
limited by hardware.

Power Save
Mode

Specify:
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.

Statements FCC

Network Type Specifies the network as either infrastructure or ad hoc.

802.11b
Preamble

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.

Authentication
Mode

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.
For infrastructure (access point) networks, click the Preferred APs button to specify up to
four access points to which the adapter should attempt to associate.

Security Tab
In the Atheros Client Utility, access the Security tab by clicking New or Modify on the
Profile Management tab. Click the Security tab in the Profile Management window.
Edit the fields in the Security tab of Profile Management to configure the profile. To
define the security mode, select the radio button of the desired security mode. Make sure
to also edit the General and Advanced tabs.

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.

Statements FCC

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.
