Config - Encryption Tab
Lets you configure the ASUS WLAN Card encryption settings. For data confidentiality in a wireless environment, IEEE 802.11 specifies a Wired
Equivalent Privacy (WEP) algorithm to offer transmission privacy similar to wired network. The WEP uses keys to encrypt transmit data packets and decrypt received data packets. The encryption process can scramble frame bits to avoid disclosure to others.

Data encryption (WEP enabled)
This option allows you to enable or disable the Wired Equivalent Privacy (WEP) function. If this check box is selected, a WEP Key is used to encrypt your data before it is transmitted over the air.
If you enable WEP encryption, you will only be able to communicate with wireless devices that have use the same WEP keys.
WEP Key
This option is enable only if you enable WEP Encryption. The WEP Key is a
64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypt transmit data packets and decrypt received data packets.
Key Format
You can enter the WEP Key as a Hexadecimal digits (0~9, a~f, and A~F), or as
ASCII characters, based on the state of the Key Format.

Key Length
For 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCII characters. For 128 bits encryption, each Key contains exactly 26 hex digits, or
13 ASCII characters.
Two ways to assign WEP keys
1. Manual Assignment - When you click this button, the cursor appears in the field for Key 1. For 64-bit encryption, you are required to enter four WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and
A~F). For 128-bit encryption, you are required to enter four WEP Keys.
Each Key contains exactly 26 hex digits (0~9, a~f, and A~F).
2. Automatic Generation - Type a combination of up to 64 letters, numbers, or symbols in the Passphrase column, then the Wireless Settings
Utility uses an algorithm to generate four WEP Keys for encryption.
NOTE: This function ease users from having to remember their passwords and is compatible to some existing WLAN utilities, but it is not very secure. "Manual Assignment" is more secure.
Default Key
The Default Key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the down arrow at the right of this field, selecting the number of the key you want to use and then clicking the Apply button. As long as the Access
Point or station with which you are communicating has the same key in the same position, you can use any of the keys as the default.
You then click the Apply button to create your encryption keys. After you click the Apply button, the Wireless Settings Utility uses asterisks to mask your keys.

NOTE: Click the Apply or OK button to save the encryption settings. The keys you entered will be masked by asterisks.
