Wireless-G Ethernet Bridge

Chapter 3:

Configuration using the

Web-based Utility

The Bridge is designed to function properly after you

configure it using the Setup Wizard. However, if you would

like to change these basic settings or make advanced

configuration changes, use your web browser and the

Wireless-G Ethernet Bridge Web-based Utility. This chapter

explains how to use the Utility.

How to Access the Web-Based Utility

Open

your

web

browser,

and

enter

the

address

of the Wireless-G Ethernet Bridge (the default is

192.168.1.226

) in the browser’s

Address

field. Then

press

Enter

Internet Explorer Address Bar

The

Password

screen will appear. In lowercase letters,

enter the default password,

admin

, in the

Password

field. Click

. You can set a new password on the

Password

screen later.

Password Screen

The

utility’s

Setup

screen

will

appear.

The

Utility

provides a convenient, web-browser-based way to

alter the Bridge’s settings. It offers five main tabs

Setup

•

- Enables you to configure the IP address and

wireless settings.

Password

•

- Allows you to change the password or

reset all settings to factory defaults.

Advanced

•

- Lets you change the advanced wireless

settings and clone a MAC address onto the Bridge.

Status

•

- Displays the Bridge’s current settings.

Help

•

- Provides explanations of various configuration

settings and links to online technical support resources.

You can also upgrade the Bridge’s firmware using the

Help screen.

Setup Tab

The

Setup

screen lets you configure the wired and wireless

network settings for the Bridge.

Setup

Firmware

The version number of the Bridge’s firmware is

displayed here. Firmware should be upgraded ONLY if you

experience problems with the Bridge. Firmware updates

are posted at

www.linksys.com

MAC Address

The Bridge’s MAC address is displayed here

LAN

Device Name

You may assign any name to the Bridge.

Unique, memorable names are helpful, especially if you

are using multiple bridges on the same wireless network.

Configuration Type

If the Bridge will obtain an IP

address automatically from a DHCP server, such as a

router, then select

Automatic Configuration-DHCP

. If

you are assigning the Bridge a static IP address, then select

Static IP Address

, and enter an IP Address, Subnet Mask,

and Gateway address in the

IP Address

Subnet Mask

, and

Gateway

fields.

Wireless

SSID

The SSID is the network name shared among all

devices in a wireless network. The SSID must be identical

for all devices in the wireless network. It is case-sensitive

and must not exceed 32 alphanumeric characters (A-Z,

a-z, 0-9; do not use spaces). Make sure this setting is the

same for all devices in your wireless network. For added

security, Linksys recommends that you change the default

SSID (linksys) to a name of your choice.

multiple wireless-equipped devices to communicate

directly with each other.

If you chose Ad-Hoc mode, then select the correct

operating channel for your network from the

Channel

drop-down menu. This should match the channel setting

of the other devices in your wireless network.

Select the appropriate network mode from the

Security

From the

Security Mode

drop-down menu, select one of the

four wireless security modes supported by the Bridge:

WPA (Wi-Fi Protected Access) Pre-Shared Key

•

WPA RADIUS

•

RADIUS (Remote Authentication Dial-In User Service)

•

WEP (Wired Equivalent Privacy)

•

WPA is a security standard stronger than WEP encryption.

The four security modes are briefly discussed here. For

detailed instructions on configuring wireless security for

the Bridge, refer to the “Wireless Security” chapter.

Wireless-G Ethernet Bridge

WEP

Use the

WEP

screen to configure the WEP encryption for

the Bridge.

Security > WEP

Select a

Default Transmit Key

(choose which Key to use),

and a level of

WEP Encryption

64 bits (10 hex digits)

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 the other

wireless-equipped devices are using the same key.

WEP Encryption

In order to use WEP encryption, select

64-Bit (10 hex digits)

128-Bit (26 hex digits)

from the

drop-down menu.

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.

(The Passphrase function is compatible with Linksys

wireless products only. If you want to communicate with

non-Linksys wireless products, you will need to enter your

WEP key manually on the non-Linksys wireless products.)

After you enter the Passphrase, click

Generate

to create

WEP key(s).

Keys 1-4

If you are not using a Passphrase, then you can

enter one or more WEP keys manually.

In each key field, manually enter a set of values. (Do not

leave a key field blank, and do not enter all zeroes. These

are not valid key values.) If you are using 64-bit WEP

encryption, then each key must consist of exactly 10

hexadecimal characters in length. If you are using 128-bit

WEP encryption, then each key must consist of exactly

26 hexadecimal characters in length. Valid hexadecimal

characters are “0”-“9” and “A”-“F”.

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

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

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)

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.
