Chapter 3 - Software Configuration

Access Point

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.

Passphrase

Selecting “WEP-64bits” or “WEP-128bits” in the Encryption field generates four

WEP keys automatically. A combination of up to 64 letters, numbers, or symbols is

required. Alternatively, leave this field blank and type in four WEP keys manually.

WEP-6bit key:

10 hexadecimal digits (0~9, a~f, and A~F)

WEP-128bit key: 26 hexadecimal digits (0~9, a~f, and A~F)

Note: The ASUS WLAN family of products uses the same algorithm to generate WEP keys,

eliminating the need for users to remember passwords and to maintain compatibility between

products. However, using this method to generate WEP keys is not as secure as manual

assignment.

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 64bits or

128bits in the WEP pull-down menu. The ASUS 802.11g AP and ALL of its wireless

clients MUST have at least the same default key.

Key Index

The Default Key field lets you specify which of the four encryption keys you use to

transmit data on your wireless LAN. As long as the ASUS 802.11g AP 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. If the ASUS 802.11g AP

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.

Network Rotation Key Interval

This field specifies the time interval (in seconds) after which a WPA group key is

changed. Enter ‘0’ (zero) to indicate that a periodic key-change is not required.
