WEP. WEP is a basic encryption method, which is not as secure as WPA. To use WEP, select a Default Key (choose which Key to use), and a level of WEP encryption, 64 bits 10 hex digits or 128 bits 26 hex digits. Then either generate a WEP key using a Passphrase or enter the WEP key manually.

WEP Encryption. An acronym for Wired Equivalent Privacy, WEP is an encryption method used to protect your wireless data communications. WEP uses 64-bit or 128-bit keys to provide access control to your network and encryption security for every data transmission. To decode data transmissions, all devices in a network must use an identical WEP key. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption, they may decrease network performance. To enable WEP, select 64 bits (10 hex digits) or 128 bits (26 hex digits).

Default Transmit Key Select which WEP key (1-4) will be used when the Gateway sends data. Make sure that the receiving device (wireless client) is using the same key.

Passphrase. Instead of manually entering WEP keys, you can enter a passphrase. This passphrase is used to

generate one or more WEP keys. It is case-sensitive and should not be longer than 32 alphanumeric

characters. (This Passphrase function is compatible with Linksys wireless products only and cannot be used

 

with Windows XP Zero Configuration. If you want to communicate with non-Linksys wireless products or

 

Windows XP Zero Configuration, make a note of the WEP key generated in the Key 1 field, and enter it

 

manually in the wireless client.) After you enter the Passphrase, click the Generate button to create WEP

 

keys.

 

WEP Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do not enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be exactly 26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
