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-64bit 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.
