Configuration using the Web-based Utility

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  Select the authentication method: MD5, TLS, or TTLS. The appropriate screen appears depending on the selection. The screens are described below.

MD5

Security > RADIUS-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.

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 Generate 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.

TLS

TLS is a mutual authentication method that uses digital certificates.
