The following section explains low-level (64-bit) and high-level (128-bit) WEP Encryption schemes:
64-bit WEP Encryption
64-bit WEP and 40-bit WEP are the same encryption methods and can interoperate in a wireless network. This level of WEP encryption uses a 40-bit (10 Hex character) encryption scheme as a secret key, which is set by the user, and a 24-bit “Initialization Vector” scheme, which is not under user control.
Together these two schemes make a 64-bit (40 + 24) encryption scheme. Some vendors refer to this level of WEP as 40-bit and others refer to this as 64-bit. ASUS WLAN products use the term 64-bit when referring to this lower level of encryption.
128-bit WEP Encryption
104-bit WEP and 128-bit WEP are the same encryption method and can interoperate on a wireless network. This level of WEP encryption uses a 104-bit (26 Hex character) encryption scheme as a secret key which is set by the user, and a 24-bit “Initialization Vector”, which is not under user control.
Together these two schemes make a 128-bit (104 + 24) encryption scheme. Some vendors refer to this level of WEP as 104-bit and others refer to this as 128-bit. ASUS WLAN products use the term 128-bit when referring to this higher level of encryption.
Key Index
The Default Key field lets you specify which of the four encryption keys to use to transmit data on your wireless LAN. As long as the ASUS WL-330N3G or wireless mobile client with which you are communicating has the same key in the same position, you can use any of the keys as the default key.
WEP Key
You can set a maximum of four WEP keys. A WEP key is either 10 or 26 hexadecimal digits (0~9, a~f, and A~F) based on whether you select 64-bits or 128-bits in the WEP pull-down menu. The ASUS WL-330N3G and ALL of its wireless clients MUST have at least the same default key.
If the ASUS WL-330N3G and ALL of its wireless clients use the same four WEP keys, select “key rotation” to maximize security. Otherwise, choose one key in common as the default key.
