What You Need to Know About Wireless
Wireless Basics
“Wireless” is essentially radio communication. In the same way that walkie-talkie radios send
and receive information over the airwaves, wireless networking devices exchange information
with one 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.

Before You Start
Before you start using these screens, ask yourself the following questions. See
Section 7.1.2
on page 106
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.
