Wireless network terms and concepts

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 which is technically referred to as an SSID

(Service Set Identifier) 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 with the wireless

network should match the access point. The access point and wireless network devices regularly send

wireless packets (referred to as beacons) containing the SSID information. When your wireless network

device receives a beacon, you can identify wireless networks within range of your device.



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 running a wireless network. However, in many countries the

number of available channels is restricted.

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

printer, it will not be able to connect to the wireless network. Be careful when configuring these options.
