You don’t necessarily need to use all these screens to set up your wireless 
connection. For example, you may just want to set up a network name, a wireless 
radio channel and security in the AP screen.

“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.

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. 

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.

networks.

Before you start using these screens, ask yourself the following questions. See 

 if some of the terms used here are not familiar to you.
