Specifying your network

SSID (Service Set Identifier) and channels

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 an SSID. 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 beacons), which have the SSID
information. When your wireless network device receives a beacon, you can identify wireless networks
that are close enough to connect to.

Channels
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 is restricted.

Security terms

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
machine, it will not be able to connect to the wireless network. Therefore care must be taken when
configuring these options. Please see Supported protocols and security features on page 137 for which
authentication and encryption methods your Brother wireless machine supports.
