Signal Problems
Because wireless networks are radio networks, their signals are subject to
limitations of distance, interference and absorption.
Problems with distance occur when the two radios are too far apart. Problems with
interference occur when other radio waves interrupt the data signal. Interference
may come from other radio transmissions, such as military or air traffic control
communications, or from machines that are coincidental emitters such as electric
motors or microwaves. Problems with absorption occur when physical objects
(such as thick walls) are between the two radios, muffling the signal.
7.3 Before You Begin
Before you start using these screens, ask yourself the following questions. See
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.
7.4 The General Screen
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.
