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. 18.3 Before You Begin Before you start using these screens, ask yourself the following questions. See Section 18.2 on page 142 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. 18.4 Wireless Basic Click Wireless to open the Basic screen. 144 P-663HN-51 User's Guide
