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(s) manually on the non-Linksys wireless products.] After you enter the Passphrase, click the Generate button to create WEP keys.

Keys 1-4WEP keys enable you to create an encryption scheme for wireless LAN transmissions. 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.) Keys 1-4 offer 64-bit or 128-bit encryption.

If you are using 64-bit WEP encryption, then the key must be exactly 10 hexa- decimal 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”.

Check all the values, and click the Apply button to save your 2.4GHz, Wireless- G WEP settings.
