Welcome
Home Wireless-G PC Card
Chapter 1: Introduction
Welcome
Thank you for choosing the Home Wireless-G PC Card. With this PC Card, your wireless networking experience
will be faster and easier than ever.
How does the PC Card do this? Like all wireless products, the PC Card allows for greater range and mobility
within your wireless network, whether it’s using the Wireless-G (802.11g) or Wireless-B (802.11b) standard.
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.
The included Setup Wizard walks you through configuring the PC Card to your wireless network settings, step by
step. Use the instructions in this Guide to help you set up and connect the PC Card using the Setup Wizard. These
instructions should be all you need to get the most out of the PC Card.

Network Topology
Home Wireless-G PC Card
Chapter 2: Planning your Wireless Network
Network Topology
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
infrastructurenetwork can talktoany computer ina wirednetworkinfrastructure 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, provided that they
both share the same channel and SSID.
Choose a feasible radio channel and optimum access point position. Proper access point positioning combined
with a clear radio signal will greatly enhance performance.
infrastructure: a wireless network that is
bridged to a wired network via an access point.
ad-hoc: a group of wireless devices
communicating directly with each other (peer-
to-peer) without the use of an access point.
roaming: the ability to take a wireless device
from one access point's range to another without
losing the connection.
ssid: your wireless network's name.
topology: the physical layout of a network.

Linksys wireless access points and wireless routers have been designed for use with 802.11b and 802.11g
products. Products using the 802.11g and 802.11b standards can communicate with each other.
Access points and wireless routers are compatible with 802.11b and 802.11g adapters, such as the notebook
adapters for your laptop computers, PCI adapters for your desktop PCs, and USB adapters for when you want to
enjoy USB connectivity. Wireless products will also communicate with a wireless print server.
When you wish to connect your wireless network to your wired 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/international for more information about wireless products.

3. The Setup Wizard will ask you to choose a network mode. Click the Infrastructure Mode radio button if you
want to connect to a wireless router or access point. Click the Ad-Hoc Mode radio button if you want to
connect directly to another wireless device without using a wireless router or access point.
In the SSID field, enter the SSID or name of your wireless network. The SSID must be identical for all devices
in the network. The default setting is linksys (all lowercase). Click the Next button.
4. Ifyou choseInfrastructure 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, keep the default channel.
Network Mode - Select Mixed Mode if you want to allow Wireless-G and Wireless-B computers on the
network, even though network speeds will be reduced. For maximum speed, select G-Only Mode; however,
no Wireless-B users will be allowed on the network.

5. If you don’t want to use encryption, select Disabled and then click the Next button to continue. Proceed to
Step 7.
Select the method of security you want to use: WEP or WPA Personal. WEP stands for Wired Equivalent
Privacy, and WPA stands for Wi-Fi Protected Access.
Click the Next button to continue or the Back button to return to the previous screen.
6. Proceed to the appropriate section for your security method: WEP or WPA Personal.
WEP
WEP - Select 64-bit or 128-bit encryption from the drop-down menu, and enter a passphrase or WEP key.
Passphrase - 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. For 64-bit encryption,
enter exactly 10 hexadecimal characters. For 128-bit encryption, enter exactly 26 hexadecimal characters.
Valid hexadecimal characters are “0” to “9” and “A” to “F”.
Advanced Users
TX Key -The defaulttransmit key number is 1. If yournetwork’saccesspoint orwireless router uses transmit
key number 2, 3, or 4, select the appropriate number from the TX Key drop-down box.
Authentication -The default is set to Auto, so it will auto-detect for Shared Key or Open System
authentication. For Shared Key authentication, both the sender and the recipient share a WEP key for
authentication. For Open System authentication, the sender and the recipient do not share a WEP key for
authentication. If you are not sure which authentication method to select, keep the default, Auto.
Click the Next button to continue. Click the Back button to return to the previous screen.
