Setup
Wireless-G Ethernet Bridge
RADIUS
This option features WEP used in coordination with a RADIUS server. (This should only be used when a
RADIUS server is connected to the Router.) It offers three authentication methods: MD5, TLS, and TTLS.
EAP Type
MD5
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 7-8.)
•
Default Transmit Key Select which WEP key (1-4) will be used when the Bridge sends data. Make sure that
the receiving device (wireless client) is using the same key.
•
WEP Encryption. 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. Select
64 bits (10 hex digits)
or
128
bits (26 hex digits)
.
•
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 32 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.
•
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”.
•
User ID and Password. A user identification and password are required for your security. Enter the ID in the
User ID
field, then the password in the
Password
field.
