(Shared Mode) option if you wish to use a network key to authenticate a preferred wireless network. Unchecking this option allows the network to operate on an Open System mode. Key Format allows you to set a hexadecimal digit or ASCII character WEP key. Key Length allows you to choose a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters. 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 assign by the WiFi-b. 104-bit and 128-bit WEP keys use the same encryption method. All wireless clients in a network must have identical WEP keys to communicate with each other or with an access point. 4-6 ASUS WiFi-b Card Two ways to assign WEP keys Manual Assignment. For a 64-bit encryption, enter 10 hexadecimal digits (0~9, a~f, A~F) or 5 ASCII characters in each of the four WEP keys.
