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. (See Figure 6-16.)

• 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)
or
128 bits (26 hex digits)
.
• Passphrase for keys. 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 Wireless AP VPN Router wireless
products only and cannot be used
with Windows XP Zero Configuration. If you want to communicate with non-Wireless AP VPN
Router 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.
• 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”.
