CHAPTER 8

Wireless LAN Setup

This chapter discusses how to configure Wireless LAN on the Prestige.

8.1 Introduction

This section introduces the wireless LAN and some basic configurations. Wireless LANs can be as simple as two computers with wireless LAN cards communicating in a peer-to-peer network or as complex as a number of computers with wireless LAN cards communicating through access points which bridge network traffic to the wired LAN.

8.1.1Additional Installation Requirements for Using 802.1x

•A computer with an IEEE 802.11b/g wireless LAN card and equipped with a web browser (with JavaScript enabled) and/or Telnet.

•A wireless station computer must be running IEEE 802.1x-compliant software. Not all Windows operating systems support IEEE 802.1X (see the Microsoft web site for details). For other operating systems, see its documentation. If your operating system does not support IEEE 802.1X, then you may need to install IEEE 802.1X client software.

•An optional network RADIUS server for remote user authentication and accounting.

8.1.2Channel

A channel is the radio frequency(ies) used by IEEE 802.11b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.

Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.
