Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G Notebook Adapter. With this Adapter, your wireless networking experience
will be faster and easier than ever.
Like all wireless products, the Adapter allows for greater range and mobility within your wireless network. This
adapter communicates over the 54Mbps 802.11g wireless standard, which is almost five times faster than
802.11b. But since they share the same 2.4GHz radio band, the Adapter can also communicate with the widely
used 11Mbps 802.11b standard.
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. For more information
about wireless networks, refer to Chapter 2: Planning Your Wireless Network.
The included Setup Wizard will walk you through configuring the adapter to your network's settings, step by step.
Then just slide it into your computer's PC Card slot and enjoy your wireless network. Future changes to your
network settings can be made with the Wireless Network Monitor, explained in Chapter 6.
Further information about the Adapter’s functions can be found in Appendix A: Troubleshooting. If you’re
concerned about wireless security, Appendix B shows you how to keep your network secure. Further appendices
provide more information about the Adapter and networking in general to help you get the most out of the
Wireless-G Notebook Adapter.

Chapter 2: Planning your Wireless Network
Network Topology
topology: the physical layout of a network.
A wireless network is a group of computers, each equipped with one wireless adapter. Computers in a wireless
network must be configured to share the same radio channel. Several PCs equipped with wireless cards or
adapters can communicate with one another to form an ad-hoc network.
Linksys wireless adapters also provide users access to a wired network when using an access point or wireless
router. An integrated wireless and wired network is called an infrastructure network. Each wireless PC in an
infrastructure network can talk to any computer in a wired network infrastructure via the access point or wireless
router.
An infrastructure configuration extends the accessibility of a wireless PC to a wired network, and can double the
effective wireless transmission range for two wireless adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an infrastructure network can be doubled.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. Roaming means that you can move your
wireless PC within your network and the access points will pick up the wireless PC's signal, providing that they
both share the same channel and SSID.
access point: a device that allows wireless-equipped
computers and other devices to communicate with a wired
network. Also used to expand the range of a wireless network
ad-hoc: a group of wireless devices
communicating directly with each other (peerto-peer) without the use of an access point.
infrastructure: a wireless network that is
bridged to a wired network via an access point.
router: a networking device that
connects multiple networks together.
roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.
Before enabling you consider roaming, choose a feasible radio channel and optimum access point position.
Proper access point positioning combined with a clear radio signal will greatly enhance performance.

ssid: your wireless network's name.

Network Layout
Linksys wireless access points and wireless routers have been designed for use with 802.11a, 802.11b, and
802.11g products. With 802.11g products communicating with the 802.11b standard and some products
incorporating both “a” and “g”, products using these standards can communicate with each other.
Access points and wireless routers are compatible with 802.11a, 802.11b and 802.11g adapters, such at the PC
Cards for your laptop computers, PCI Card for your desktop PC, and USB Adapters for when you want to enjoy USB
connectivity. Wireless products will also communicate with the wireless PrintServer.
When you wish to connect your wired network with your wireless network, network ports on access points and
wireless routers can be connected to any of Linksys's switches or routers.
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at
www.linksys.com for more information about wireless products.
802.11a: a wireless networking standard that
specifies a maximum data transfer rate of
54Mbps and an operating frequency of 5GHz.
switch: a data switch that connects computing
devices to host computers, allowing a large number of
devices to share a limited number of ports

The Installation Procedure
1. To install the Adapter, click the Install button on the Welcome screen.
2. After reading the License Agreement, click the Next button if you agree, or click the Cancel button to end the
installation.
3. The Setup Wizard will ask you to choose a network mode. Click the Infrastructure Mode radio button if you
want your wireless computers to network with computers on your wired network using an access point or
wireless router. Click the Ad-Hoc Mode radio button if you want multiple wireless computers to network
directly with each other.
Figure 4-2: The Setup Wizard’s License Agreement
In the SSID field, enter your wireless network’s SSID. The SSID must be identical for all devices in the
network. The default setting is linksys (all lowercase). Click the Next button.
NOTE: Network SSIDs should be unique to your network
and identical for all devices within the network.

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. Then, select the Network Mode from the drop-down 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 - Select the type of network you have, mixed (Wireless-G and Wireless-B) or G-Only (only
Wireless-G). If you select Mixed Mode, both Wireless-G and Wireless-B computers will be allowed on the
network, which may reduce your speed. Select G-Only Mode for maximum speed, but no Wireless-B users
will be allowed on the network.
5. Select the type of security you want to use: 64-bit WEP, 128-bit WEP, or WPA-PSK. All devices in a network
must use the same type.
WEP
Security - To use WEP encryption, select 64-bits or 128-bit characters from the drop-down menu, and enter
a passphrase or WEP key.
Figure 4-4: The Setup Wizard’s Ad-Hoc Mode Screen
Passphrase - Instead of manually entering a WEP key, you can enter a passphrase in the Passphrase field, so
a WEP key is automatically generated. It is case-sensitive and should not be longer than 16 alphanumeric
characters. This passphrase must match the passphrase of your other wireless network devices and is
compatible with Linksys wireless products only. (If you have any non-Linksys wireless products, enter the
WEP key manually on those products.)
WEP Key - The WEP key you enter must match the WEP key of your wireless network. If you are using 64-bit
WEP encryption, then the key must consist of exactly 10 hexadecimal characters. If you are using 128-bit
WEP encryption, then the key must consist of exactly 26 hexadecimal characters. Valid hexadecimal
characters are “0” to “9” and “A” to “F”.
Transmit Key - The default transmit key number is 1. If your network’s access point or wireless router uses
transmit key number 2, 3, or 4, select the appropriate number from the Transmit Key drop-down box.
Authentication -The default is set to Auto, where it auto-detects for Shared Key or Open system. Shared
Key is when both the sender and the recipient share a WEP key for authentication. Open key is when the
sender and the recipient do not share a WEP key for authentication. All points on your network must use the
same authentication type.

characters in the Passphrase field.
Click the Next button to continue. Click the Back button to return to the previous screen. Click the Help
button for more information.
6. The Setup Wizard will ask you to review and finalize your settings before it starts to install files. Click Next if
you are satisfied with your settings, or click Back to change any settings.
