Radio Channels
In the radio spectrum, there are certain frequency bands allocated for unlicensed,
civilian use. For the purposes of wireless networking, these bands are divided into
numerous channels. This allows a variety of networks to exist in the same place
without interfering with one another. When you create a network, you must select
a channel to use.
Since the available unlicensed spectrum varies from one country to another, the
number of available channels also varies.
6.1.3 Before You Begin
Before you start using these screens, ask yourself the following questions. See
Section 6.7 on page 127 if some of the terms used here do not make sense to
you.
• What wireless standards do the other wireless devices support (IEEE 802.11g,
for example)? What is the most appropriate standard to use?
• What security options do the other wireless devices support (WPA-PSK, for
example)? What is the best one to use?
• Do the other wireless devices 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, ensure that you know precisely what you want to
do. If you do not want to configure advanced options, leave them alone.
6.2 The Wireless General Screen
Use this screen to enable the Wireless LAN, enter the SSID and select the wireless
security mode.
Note: If you are configuring the ZyXEL Device from a computer connected to the
wireless LAN and you change the ZyXEL Device’s SSID or security settings,
you will lose your wireless connection when you press
Apply to confirm. You
must then change the wireless settings of your computer to match the ZyXEL
Device’s new settings.
