Introduction

Types of network connections 1

Network connection example 1

Generally there are two types of network connections: Peer-to-Peer and Network Shared environment.

Peer-to-Peer printing using TCP/IP 1

In a Peer-to-Peer environment, each computer directly sends and receives data to each device. There is no
central server controlling file access or printer sharing.

2 Network printer (your machine)

 In a smaller network of 2 or 3 computers, we recommend the Peer-to-Peer printing method as it is easier

to configure than the Network Shared printing method described on the following page. See Network
Shared printing on page 5.

 Each computer must use the TCP/IP Protocol.
 The Brother machine needs to have an appropriate IP address configuration.
 If you are using routers, the Gateway address must be configured on the computers and the Brother

machine.

 The Brother machine can also communicate with Macintosh

®

(TCP/IP compatible operating systems).

4

Introduction

Network Shared printing 1

In a Network Shared environment, each computer sends data via a centrally controlled computer. This type
of computer is often called a “Server” or a “Print Server”. Its job is to control the printing of all print jobs.

1 Client computer

2 Also known as “Server” or “Print server”

3 TCP/IP or USB (where available)

4 Printer (your machine)

 In a larger network, we recommend a Network Shared printing environment.
 The “server” or the “print server” must use the TCP/IP print protocol.
 The Brother machine needs to have an appropriate IP address configuration unless the machine is

connected via the USB interface at the server.

Introduction

Wireless network connection examples 1

Connected to a computer with an access point on the network (Infrastructure mode) 1

This type of network has a central access point at the heart of the network. The access point can also act as
a bridge or a gateway to a wired network. When the Brother wireless machine (your machine) is part of this
network, it receives all print jobs via an access point.

1 Access point

2 Wireless network printer (your machine)

3 Wireless capable computer communicating with the access point

4 Wired computer which is not wireless capable connected to the access point with the Ethernet

cable

Connected to a wireless capable computer without an access point on the network (Ad-hoc mode) 1

This type of network does not have a central access point. Each wireless client communicates directly with
each other. When the Brother wireless machine (your machine) is part of this network, it receives all print jobs
directly from the computer sending the print data.

Configuring your machine for a network 2

Overview 2

Before using your Brother machine in a network environment, you must install the Brother software and also
configure the appropriate TCP/IP network settings on the machine itself. In this chapter, you will learn the
basic steps required to print over the network using TCP/IP protocol.

We recommend that you use the Brother installer on the Brother CD-ROM to install the Brother software as
this will guide you through the software and network installation. Please follow the instructions in the supplied
Quick Setup Guide.

If you do not wish to, or are unable to use the Brother installer or any of Brother’s software tools, you can
also use the machine’s control panel to change network settings. For more information, see Control panel
setup on page 74.

IP addresses, subnet masks and gateways 2

2

To use the machine in a networked TCP/IP environment, you need to configure the IP address and subnet
mask. The IP address you assign to the print server must be on the same logical network as your host
computers. If it is not, you must properly configure the subnet mask and the gateway address.

IP address 2

An IP address is a series of numbers that identifies each computer connected to a network. An IP address
consists of four numbers separated by dots. Each number is between 0 and 255.

 Example: In a small network, you would normally change the final number.

• 192.168.1.1

• 192.168.1.2

• 192.168.1.3

address on page 125, Using BOOTP to configure the IP address on page 126 and Using RARP to configure
the IP address on page 127.

If you do not have a DHCP/BOOTP/RARP server, the Automatic Private IP Addressing (APIPA) protocol will
automatically assign an IP address from the range 169.254.1.0 to 169.254.254.255. For more information on
APIPA, see Using APIPA to configure the IP address on page 127.

If the APIPA protocol is disabled, the IP address of a Brother print server is 192.0.0.192. However, you can
easily change this IP address number to match with the IP address details of your network. For information
on how to change the IP address, see Setting the IP address and subnet mask on page 13.

or Windows Server® 2003 network) the print server will automatically obtain its IP address

Subnet mask 2

Subnet masks restrict network communication.

 Example: Computer 1 can talk to Computer 2

• Computer 1
IP Address: 192.168.1.2
Subnet Mask: 255.255.255.0

• Computer 2
IP Address: 192.168.1.3
Subnet Mask: 255.255.255.0

0 denotes that there is no limit to communication at this part of the address.

In the above example, we can communicate with anything that has an IP address that begins with

192.168.1.x.

Gateway (and router) 2

A gateway is a network point that acts as an entrance to another network and sends data transmitted via the
network to an exact destination. The router knows where to direct data that arrives at the gateway. If a
destination is located on an external network, the router transmits data to the external network. If your network
communicates with other networks, you may need to configure the Gateway IP address. If you do not know
the Gateway IP address then contact your Network Administrator.

Overview 3

To connect your machine to your wireless network, we recommend you to follow the steps in the Quick Setup
Guide using the Setup Wizard from the machine’s control panel LAN menu. By using this method, you can
easily connect your machine to your wireless network.

Please read this chapter for additional methods on how to configure the wireless network settings. For
information on TCP/IP settings, see Setting the IP address and subnet mask on page 13 and Using the

BRAdmin Light utility to configure your machine as a network printer on page 13. Then, in Network printing
from Windows

on page 103, you will learn how to install the network software and drivers into the operating system running
on your computer.

• To achieve optimum results with normal every day document printing, place the Brother machine as close
to the network access point (or router) as possible with minimal obstructions. Large objects and walls
between the two devices as well as interference from other electronic devices can affect the data transfer
speed of your documents.

Due to these factors, wireless may not be the best method of connection for all types of documents and
applications. If you are printing large files, such as multi-page documents with mixed text and large
graphics, you may want to consider choosing wired Ethernet for a faster data transfer, or USB for the
fastest throughput speed.

Configuring your machine for a wireless network

Wireless network terms and concepts 3

When you configure your machine for a wireless network, you must ensure that your wireless network
machine is configured to match the settings of the existing wireless network. This section provides some of
the main terms and concepts of these settings, which may be helpful when you configure your machine for a
wireless network.

SSID (Service Set Identifier) and channels 3

You need to configure the SSID and a channel to specify the wireless network you want to connect to.

 SSID

Each wireless network has its own unique network name and it is technically referred to as SSID or ESSID
(Extended Service Set Identifier). The SSID is a 32-byte or less value and is assigned to the access point.
The wireless network devices you want to associate to the wireless network should match the access
point. The access point and wireless network devices regularly send wireless packets (referred to as a
beacon) which has the SSID information. When your wireless network device receives a beacon, you can
identify the wireless network that is close enough for the radio waves to reach your device.

 Channels

3

Wireless networks use channels. Each wireless channel is on a different frequency. There are up to 14
different channels that can be used when using a wireless network. However, in many countries the
number of channels available are restricted. For further information, see Ethernet wireless network
on page 134.

Authentication and encryption 3

Most wireless networks use some kind of security settings. These security settings define the authentication
(how the device identifies itself to the network) and encryption (how the data is encrypted as it is sent on the
network). If you do not correctly specify these options when you are configuring your Brother wireless device,
it will not be able to connect to the wireless network. Therefore care must be taken when configuring these
options. Please refer to the information below to see which authentication and encryption methods your
Brother wireless device supports.

Authentication methods 3

The Brother printer supports the following methods:

 Open system

Wireless devices are allowed access the network without any authentication.

 Shared key

A secret pre-determined key is shared by all devices that will access the wireless network.
The Brother wireless machine uses the WEP keys as the pre-determined key.

20

Configuring your machine for a wireless network

 WPA-PSK/WPA2-PSK

Enables a Wi-Fi

®

Protected Access Pre-shared key (WPA-PSK/WPA2-PSK), which enables the Brother
wireless machine to associate with access points using TKIP for WPA-PSK or AES for WPA-PSK and
WPA2-PSK (WPA-Personal).

 LEAP

®

Cisco

LEAP (Light Extensible Authentication Protocol) has been developed by Cisco Systems, Inc. which

uses user ID and password for authentication.

Encryption methods 3

Encryption is used to secure the data that is sent over the wireless network. The Brother wireless machine
supports the following encryption methods:

 None

No encryption method is used.

 WEP

By using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure key.

 TKIP

3

TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing a message integrity check and
rekeying mechanism.

 AES

AES (Advanced Encryption Standard) is the Wi-Fi

®

authorized strong encryption standard.

 CKIP

The original Key Integrity Protocol for LEAP by Cisco Systems, Inc.

Network key 3

There are some rules for each security method:

 Open system/Shared key with WEP

This key is a 64-bit or 128-bit value that must be entered in an ASCII or hexadecimal format.

• 64 (40) bit ASCII:
Uses 5 text characters. e.g. “WSLAN” (this is case sensitive).

• 64 (40) bit hexadecimal:
Uses 10 digits of hexadecimal data. e.g. “71f2234aba”

• 128 (104) bit ASCII:
Uses 13 text characters. e.g.“Wirelesscomms” (this is case sensitive)

• 128 (104) bit hexadecimal:
Uses 26 digits of hexadecimal data. e.g. “71f2234ab56cd709e5412aa2ba”
