Chapter 1: Introduction
Connect your USB-equipped desktop or notebook computer to a wireless network at incredible speeds with the Linksys Wireless-G USB Network Adapter.
By incorporating two new, blazing fast technologies -- USB 2.0 and WirelessG -- the Adapter delivers data rates up to 54Mbps (5 times as fast as 802.11b),
without the trouble of opening up the case of your desktop computer.
To install, simply plug the Adapter into any available USB port. (It's compatible with both USB 1.1 and 2.0 ports, but 2.0 will yield the fastest speeds.) It
gets its power through the USB connection, so no power cord is necessary. The
included Setup Wizard walks you through configuring the Adapter to your
wireless network settings, step by step. The Wireless-G USB Network Adapter
is also compatible with the Wireless-B (802.11b) network standard, with data
rates up to 11Mbps. And your wireless communications can be protected by
128-bit encryption, so your data stays secure.
The Wireless-G USB Network Adapter's high-gain antenna lets you put your
computer almost anywhere in the building, without the cost and hassle of running cables. Now you don't have to drill holes in your walls and climb through
the attic or cellar to get connected to the network. Once you're connected, you
can keep in touch with your e-mail, access the Internet, use instant messaging
to chat with friends, and share files and other resources such as printers and
hard disk storage space with other computers on the network.
So don't hassle with running cables through your house -- get connected the
easy way with the Wireless-G USB Network Adapter.
• Compatible with 802.11g and 802.11b (2.4GHz) Stardards
• Support USB 2.0 with up to 54Mbps, High-Speed Data Transfer Rate with
Automatic Fallback
• Plug-and-Play Operation Provides Easy Setup

The Wireless-G USB Network Adapter
Features
If the wireless network is relatively small and needs to share resources only
with the other computers on the wireless network, then the ad-hoc mode can
be used. (See Figure 2-2.) Ad-hoc mode allows computers equipped with wireless transmitters and receivers to communicate directly with each other, eliminating the need for an access point. The drawback of this mode is that, in AdHoc mode, wireless-equipped computers are not able to communicate with
computers on a wired network. And, of course, communication between the
wireless-equipped computers is limited by the distance and interference directly between them.

Chapter 2: Planning Your Wireless Network
A wireless local area network (WLAN) is exactly like a regular local area network (LAN), except that each computer in the WLAN uses a wireless device to
connect to the network. Computers in a WLAN share the same frequency
channel and SSID, which is an identification name for wireless devices.
Unlike wired networks, wireless networks have two different modes in which
they may be set up: infrastructure and ad-hoc. An infrastructure configura-
tion is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other. Choosing between these two modes
depends on whether or not the wireless network needs to share data or peripherals with a wired network or not.
If the computers on the
wireless network need to
be accessed by a wired
network or need to share a
peripheral, such as a printer, with the wired network
computers, the wireless
network should be set up
in infrastructure mode.
(See Figure 2-1.) The
basis of infrastructure
mode centers around an
access point, which serves
as the main point of communications in a wireless network. Access points
transmit data to PCs equipped with wireless network cards, which can roam
within a certain radial range of the access point. Multiple access points can be
arranged to work in succession to extend the roaming range, and can be set up
to communicate with your Ethernet (wired) hardware as well.

Chapter 4: Software Installation and Configuration for Windows 2000
The Wireless-G USB Network Adapter Setup Wizard will guide you through
the installation procedure. The Setup Wizard will install the WLAN Monitor
and driver, as well as configure the Adapter.
1. Insert the Setup Wizard CD-ROM into your CD-ROM drive. The Setup
Wizard should run automatically, and Figure 4-1 should appear. If it does
not, click the Start button and choose Run. In the field that appears, enter
D:\setup.exe (if “D” is the letter of your CD-ROM drive).
To install the Adapter, click the Install button on the Welcome screen. Click
User Guide to view this User Guide or click Exit to exit the Setup Wizard.

Chapter 3: Getting to Know the Wireless-G USB Network Adapter
The Network Adapter is connected to your PC through its USB port. All power
is provided through the USB connection, making a power adapter unnecessary.
The Network Adapter’s LEDs show you how the Adapter is functioning.
Power Green. This LED will light up to let you know that the Adapter is
adequately powered over the USB connection.
Link Green. The Link LED will be lit steadily when the Network
Adapter is connected to your wireless network. The LED will
blink when there is wireless network traffic.

4. If you chose
Infrastructure
Mode, go to Step
5 now. If you
chose Ad-Hoc
Mode, select the
correct operating
channel for your
network from the
Channel dropdown menu.
Then, select the
Network Mode
from the dropdown menu.
Click the Next
button, and go to Step 5. Click the Back button to change any settings.
Channel - The channel you choose should match the channel set on the
other devices in your wireless network. If you are unsure about which channel to use, select the default channel (Channel 6).
Network Mode - Keep the default setting, Mixed, if you have Wireless-G
and Wireless-B devices in your network. Select G-Only if you have only
Wireless-G devices in your network.
5. The Setup Wizard
will ask you to
review your settings before it
starts to copy
files. Click the
Next button to
save these settings, or click the
Back button to
change any settings.

2. Read the License Agreement and click the Next button to continue the
installation. If
you click the
Cancel button,
you will end the
installation.
3. The following screen, shown in Figure 4-3, will ask for some information
about your wireless network. In the SSID field, enter your network’s SSID
(Service Set Identifier). The SSID is your network name and must be identical for all devices in the network. The default setting is linksys (all lowercase).
Next, choose a wireless mode. Click the Infrastructure Mode radio button
if you want your wireless computers to network with computers on your
wired network using a wireless access point. Click the Ad-Hoc Mode radio
button if you
want multiple
wireless computers to network directly
with each other.
Click the Next
button to continue, or click the
Back button to
return to the
previous page.

6. At this point, you may see a warning screen, such as that shown in
Figure 4-6 , asking if you’d like to
cease installation. You can click
the Yes button to continue; the
Adapter will function properly.
7. After the files have been successfully copied, the screen in Figure 4-7 will
appear. Click the Exit button.
Proceed to “Chapter 5: Hardware Installation.”
