Wireless USB Adapter.

¾ PC/AT compatible computer with a USB interface.

1.5 Network Configuration

The following part will depict the possible wireless LAN PC card network configurations, which
helps you to get a better understanding of how the wireless LAN products work together in a
wireless network.

The wireless LAN products can be configured as:

Ad-hoc (peer-to-peer) Mode

This is the simplest network configuration with several computers equipped with the PC Cards
that form a wireless network whenever they are within range of one another. In ad-hoc mode,
each client is peer-to- peer, would only have access to the resources of the other client and
does not require an access point. This is the easiest and least expensive way for the SOHO to
set up a wireless network.

The image below depicts a network in ad-hoc mode.

Figure 1-1 Ad-hoc mode.

Infrastructure Mode

The infrastructure mode requires the use of an access point (AP). In this mode, all wireless
communication between two computers has to be via the AP. It doesn’t matter if the AP is
stand-alone or wired to an Ethernet network. If used in stand-alone, the AP can extend the

range of independent wireless LANs by acting as a repeater, which effectively doubles the
distance between wireless stations.

The image below depicts a network in infrastructure mode.

Chapter 2. Installation Guide

2.1 Before You Begin

The operating distance range of your wireless connection can vary significantly depending on
the physical position of the wireless devices. Factors that can weaken signals by getting in the
way of your network’s radio waves are metal appliances or obstructions, and walls. Typical
ranges vary base on the types of materials and background RF (radio frequency) noise in your
home or office.

For best performance of your wireless network, you are suggested to:

1. Place your computer with this wireless card near the operating wireless router.

2. Avoid redundant obstacles and interference between the wireless devices.

3. Keep your product far from electrical devices or appliances that generate RF noise, such
as microwave ovens, 2.4 GHz cordless phone.

2.2 Hardware Installation
