Wireless-G Cable Gateway
Wireless Security
Wireless SSID Broadcast. When wireless clients survey the local area for
wireless networks to associate with, they will detect the SSID broadcast by the
Router. To broadcast the Router's SSID, keep the default setting, Enabled. If
you do not want to broadcast the Router's SSID, then select Disabled.
Wireless 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-Wireless-G and 802.11b-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. If you
select 64-Bit Encryption, you will see the screen in Figure 5-6. If you select
128-Bit Encryption, you will see the screen in Figure 5-7. If you don’t want to
use WEP security, select No Encryption.

64-Bit Encryption
Default Key. Select which WEP key (1-4) will be used when the Router sends
data. Make sure the receiving device is using the same key.
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 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.
Wireless WEP Keys 1-4. WEP keys enable you to create an encryption scheme
for wireless LAN transmissions. If you are not using a Passphrase, then manu-
ally enter a set of values. (Do not leave a key field blank, and do not enter all
zeroes. These are not valid key values.)
For 64-bit WEP encryption, the key must be exactly 10 hexadecimal characters
in length.
