The Atheros Client Utility provides four types of encryption: Pre-Shared Keys, LEAP, Externally Managed 802.1x Keys and Disabled.

Each wireless device within a WLAN must use the same security settings to allow communication. Depending on whether you are connecting to an Ad
Hoc or Infrastructure network, you will need to consult one of the workgroup participants or network administrator for the correct security settings.

To use this option, enable the Pre-Shared Keys option on the Security tab and click Define Pre-Shared Keys to set the encryption keys. Then
configure the fields below:

Key Entry Method: Select the method to enter the key. If Hexadecimal is selected, only digits 0-9 and letters a-f, A-F are allowed. If ASCII Text is
selected, you can enter alphanumeric characters.

Key Length (bit): Defines the length for each encryption key. Key length varies according to the WEP type. As the Key Length is changed, the number
of available characters in the field is changed automatically. If an already entered key is too long, the key is automatically truncated to fit. If the key
length is increased again, the field does not automatically restore to its previous value.

Per-User Key: Defines the unique encryption key for network configuration security. This field must be populated to enable security using a unique
key. This key is not used in Ad Hoc mode.

Shared Keys (1 ~ 4): Defines a set of shared encryption keys for network configuration security. At least one Shared Key field must be populated to
enable security using a shared key.
