Welcome
Wireless-G PCI Adapter
Chapter1:Introduction
Welcome
Thank you for choosing the Wireless-G PCI 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.
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 PCI Card slot and enjoy network access with the freedom of wireless.
Once you're connected, you can keep in touch with your e-mail, access the Internet, and share files and other
resources such as printers and network storage with other computers on the network. At home, you can surf the
web or use instant messaging to chat with friends while sitting out on the patio. Your wireless connection is
protected by the new, industrial-strength security of Wireless Protected Access (WPA).
And now, with SecureEasySetup, setting up your network and your Wireless-G PCI Adapter is easier than ever.
Get connected to current-standard 802.11b networks today, and be prepared for the future with the Wireless-G
PCI Adapter from Linksys.
802.11b: an IEEE wireless networking standard
that specifies a maximum data transfer rate of
11Mbps and an operating frequency of 2.4GHz

Network Topology
Wireless-G PCI Adapter
Chapter2:PlanningyourWirelessNetwork
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
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.
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.
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.
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
