### 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.

Note: If the Profile Locked checkbox is checked, Profile cannot be removed or modified. However the password fields can be edited. Contact your system administrator.

Set Security Options

The type of security mode the station is using. The options include the following:

- WPA/WPA2/CCKM
- WPA/WPA2 Passphrase
- 802.1x
- Pre-Shared Key (Static WEP)
- None

These options define the unique encryption key for network configuration security.

WPA/WPA2

Enables the use of Wi-Fi Protected Access (WPA).

Choosing WPA/WPA2 opens the WPA/WPA2 EAP drop-down menu. The options include:

- EAP-FAST
- EAP-TLS
- EAP-TTLS
- EAP-SIM
- PEAP (EAP-GTC)
- PEAP (EAP-MSCHAP V2)
- LEAP

WPA/WPA2 Passphrase | Enables WPA/WPA2 Passphrase security. Click on the Configure button and fill in the WPA/WPA2 Passphrase.

802.1x

Enables 802.1x security. This option requires IT administration.

Choosing 802.1x opens the 802.1x EAP type drop-down menu. The options include:

- EAP-FAST
- EAP-TLS
- EAP-TTLS
- EAP-SIM
- PEAP (EAP-GTC)
- PEAP (EAP-MSCHAP V2)
- LEAP

If the access point that the wireless adapter is associating to has WEP set to Optional and the client has WEP enabled, make sure that Allow Association to Mixed Cells is checked on the Security Tab to allow association.

Pre-Shared Key
(Static WEP)

Enables the use of pre-shared keys that are defined on both the access point and the station.

To define pre-shared encryption keys, choose the Pre-Shared Key radio button and click the Configure button to fill in the Define Pre-Shared Keys window.

If the access point that the wireless adapter is associating to has WEP set to Optional and the client has WEP enabled, make sure that Allow Association to Mixed Cells is checked on the Security Tab to allow association.

None | No security (not recommended).
Allow Association to Mixed Cells | Check this check box if the access point with which the client adapter is to associate has WEP set to Optional and WEP is enabled on the client adapter. Otherwise, the client is unable to establish a connection with the access point.

Limit Time for Finding Domain Controller To

Check this check box and enter the number of seconds (up to 300) after which the authentication process times out when trying to find the domain controller. Entering zero is like unchecking this check box, which means no time limit is imposed for finding the domain controller.

Note: The authentication process times out whenever the authentication timer times out or the time for finding the domain controller is reached.

Group Policy Delay

Specify how much time elapses before the Windows logon process starts group policy. Group policy is a Windows feature used by administrators to specify configuration options for groups of users. The objective is to delay the start of Group Policy until wireless network authentication occurs. Valid ranges are from 0 to 65535 seconds. The value that you set goes into effect after you reboot your computer with this profile set as the active profile.

This drop-down menu is active only if you chose EAP-based authentication.
