Introduction
The Atheros 802.11n + Adapter supports 802.11n and EDR2.0 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.
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).
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.
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.

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.

Mode
limited by hardware.
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.
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.
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.
