another. A wireless networking device is just like a radio that lets your computer exchange
information with radios attached to other computers. Like walkie-talkies, most wireless networking
devices operate at radio frequency bands that are open to the public and do not require a license to
use. However, wireless networking is different from that of most traditional radio communications in
that there a number of wireless networking standards available with different methods of data
encryption.
SSID
Each network must have a name, referred to as the SSID - "Service Set IDentifier". The "service
set" is the network, so the "service set identifier" is the network's name. This helps you identify
your wireless network when wireless networks' coverage areas overlap and you have a variety of
networks to choose from.
MAC Address Filter
Every Ethernet device has a unique MAC (Media Access Control) address. The MAC address consists
of twelve hexadecimal characters (0-9, and A to F), and it is usually written in the following format:
"0A:A0:00:BB:CC:DD".
The MAC address filter controls access to the wireless network. You can use the MAC address of
each wireless client to allow or deny access to the wireless network.

8.1.3 Before You Start

Before you start using these screens, ask yourself the following questions. See
page 123 if some of the terms used here are not familiar to you.
• What wireless standards do the other wireless devices in your network support (IEEE 802.11g,
for example)? What is the most appropriate standard to use?
• What security options do the other wireless devices in your network support (WPA-PSK, for
example)? What is the strongest security option supported by all the devices in your network?
• Do the other wireless devices in your network support WPS (Wi-Fi Protected Setup)? If so, you
can set up a well-secured network very easily.
Even if some of your devices support WPS and some do not, you can use WPS to set up your
network and then add the non-WPS devices manually, although this is somewhat more
complicated to do.
• What advanced options do you want to configure, if any? If you want to configure advanced
options such as Quality of Service, ensure that you know precisely what you want to do. If you do
not want to configure advanced options, leave them as they are.
