Configuring your machine for a wireless network

Authentication and encryption

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

The Brother machine 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 machine uses the WEP keys as the pre-determined key.

WPA-PSK

Enables a Wi-Fi

®

 Protected Access Pre-shared key (WPA PSK), which enables the Brother wireless 

machine to associate with access points using TKIP encryption (WPA-Personal). (See 

Connected to 

wireless capable computer with an access point (router) in the network (Infrastructure mode)

 on page 

1-5).

Encryption methods

Encryption is used to secure the data that is sent over the wireless network. The Brother 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

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

If you have previously configured the wireless settings of the machine, you must reset the network (LAN) 
settings before you can configure the wireless settings again. (See 

Restoring the network settings to 

factory default

 on page 4-21)
