To assign WEP keys
Complete these steps to assign WEP keys.
Manual Assignment. For 64-bit encryption, enter 10 hexadecimal digits (0~9,
a~f, A~F) or 5 ASCII characters in each of the four WEP keys. For 128-bit
encryption, enter 26 hexadecimal digits (0~9, a~f, A~F) or 13 ASCII characters
in each of the four WEP keys.
Automatic Generation. Type a combination of up to 64 letters, numbers, or
symbols in the Passphrase field. The Wireless Settings utility uses an algorithm
to generate four WEP keys based on the typed combination.
Important:
• 64-bit and 40-bit WEP keys use the same encryption method and can
interoperate on wireless networks. This lower level of WEP encryption uses
a 40-bit (10 hexadecimal digits assigned by the user) secret key and a 24-
bit Initialization Vector assigned by the wireless LAN adapter. 104-bit and
128-bit WEP keys use the same encryption method.
• After assigning the WEP keys, click Apply to save and activate the
encryption. Manually assigned encryptions are more secure than
automatically generated encryptions.
• Use Manual Assignment instead of Automatic Generation if you are not sure
whether other wireless clients use the same algorithm as that of wireless
LAN adapter.
• Keep a record of the WEP encryption keys.
