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.

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.

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 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.

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

Client Name

Network Names (SSIDs)

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

Power Save

Mode

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

Specify:

Identifies the configuration profile. This name must be unique. Profile names are not case sensitive.

Identifies the client machine.

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).

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

802.11b

Preamble

Authentication

Mode

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.

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.

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.
