Wireless-G USB Network Adapter

Chapter 1: Introduction

Welcome

Thank you for choosing the Wireless-G USB Network Adapter. With this Adapter, your wireless networking

experience will be faster and easier than ever.

How does the Adapter do this? Like all wireless products, the Adapter allows for greater range and mobility

within your wireless network. Connecting to your PC via the USB port means that this Adapter leaves the PC’s

slots open for other purposes. This adapter communicates over the 802.11g wireless standard, one of the newest

wireless standards, to communicate with your network.

But what does all of this mean?

Networks are useful tools for sharing computer resources. You can access one printer from different computers

and access data located on another computer's hard drive. Networks are even used for playing multiplayer video

games. So, networks are not only useful in homes and offices, they can also be fun.

PCs equipped with wireless cards and adapters can communicate without cumbersome cables. By sharing the

same wireless settings, within their transmission radius, they form a wireless network.

And now, with Secure Easy Setup, setting up your network and your Wireless-G USB Network Adapter is easier

than ever.

Use the instructions in this Guide to help you connect the Adapter, set it up, and configure it for your network.

These instructions should be all you need to get the most out of the Adapter.

802.11g: an IEEE wireless networking standard that specifies a

maximum data transfer rate of 54Mbps, an operating frequency

of 2.4GHz, and backward compatibility with 802.11b devices.

adapter: a device that adds network functionality to your PC.

network: a series of computers or devices

connected for the purpose of data sharing, storage,

and/or transmission between users.
