• WEP Encryption. Select the level of WEP encryption you wish to use, 64-bit 10 hex digits or 128-bit 26 hex
digits. Higher encryption levels offer higher levels of security, but due to the complexity of the encryption,
they may decrease network performance.
• 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 16 alphanumeric
characters. (This Passphrase function is compatible with Linksys wireless products only. If you want to
communicate with non-Linksys wireless products, enter the WEP key manually on the non-Linksys wireless
products.) After you enter the Passphrase, click the Generate button to create WEP keys.
• Keys 1-4. WEP keys enable you to create an encryption scheme for wireless LAN 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. These are not valid key values.)
If you are using 64-bit WEP encryption, then the key must be exactly 10 hexadecimal characters in length. If
you are using 128-bit WEP encryption, then the key must be exactly 26 hexadecimal characters in length.
Valid hexadecimal characters are “0”-“9” and “A”-“F”.
