10.3 What You Should Know

Every wireless network must follow these basic guidelines.

• Every wireless client in the same wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set IDentity.

• If two wireless networks overlap, they should use different channels.

Like radio stations or television channels, each wireless network uses a specific channel, or

frequency, to send and receive information.

• Every wireless client in the same wireless network must use security compatible with the AP.

Security stops unauthorized devices from using the wireless network. It can also protect the

information that is sent in the wireless network.

10.3.1 Wireless Security Overview

The following sections introduce different types of wireless security you can set up in the wireless

network.

10.3.1.1 SSID

Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the

SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change

the default SSID to something that is difficult to guess.

This type of security is fairly weak, however, because there are ways for unauthorized devices to

get the SSID. In addition, unauthorized devices can still see the information that is sent in the

wireless network.

10.3.1.2 MAC Address Filter

Every wireless client has a unique identification number, called a MAC address.

A MAC address is

usually written using twelve hexadecimal characters

; for example, 00A0C5000002 or

1 2 ... 79 80 81 82 83 84 85 86 87 88 89 ... 193 194
