•
Default 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.
•
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”.
WEP. WEP is a basic encryption method, not as secure as WPA. To use WEP, select a level of WEP encryption, and
either generate a WEP key through the Passphrase or select a WEP key and a enter the WEP key manually.
•
WEP Encryption Level. 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)
(see Figure 5-17) or
128 bits (26 hex digits)
. To disable WEP encryption, keep the default
setting,
No Encryption
.
•
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 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.
