Security Settings for WEP Encryption 
When Encryption is set to WEP on the Security page for the WLAN profile, you will be able to configure 
WEP key length, WEP key index, and WEP key source. Other settings will be displayed depending on 
how WEP key source is configured. 
WEP Key Length 
Default  64bits 
Options  64bits, 128bits 
Description  This field specifies the length of the WEP key. 64bits is the industry standard for WEP, but 
128bits provides better protection. 
WEP Key Index 
Default  1
Options  1 through 4 
Description  This field specifies the primary WEP key to use for the WLAN. 
WEP Key Source 
Default  Manual 
Options  Manual, Generate WEP keys by passphrase 
Description  This field specifies whether the WEP key will be generated manually or through a user-
specified passphrase. A passphrase is equivalent to a free-text password that will be used 
to generate the WEP key. A passphrase is typically easier to remember and enter than a 
long and complicated WEP key. 
WEP Passphrase 
Default 
Options  free text (e.g., “This is the WEP passphrase”) 
Description  This field is only available if WEP key source is set to Generate WEP keys by 
passphrase. A standard hexadecimal password will be generated using the supplied 
passphrase. For example, if “404tech” is entered, the WEP key will be 
“DB971608E942FC39BD89FC4ADB”.
