64-bit WEP Encryption
64-bit WEP and 40-bit WEP are the same encryption method 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.
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. How-
ever, using this method to generate WEP keys is not as secure as
manual assignment.
