Chapter 1: Introduction

Welcome
Thank you for choosing the Wireless-G PCI Adapter with RangeBooster. 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. And with RangeBooster, the range and speed will be even greater. This adapter communicates over the 54Mbps 802.11g wireless standard, but can also communicate with the widely used 11Mbps 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.
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.

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 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.
topology: the physical layout of a network.
ad-hoc: a group of wireless devices
communicating directly with each other (peer-to­peer) without the use of an access point.
access point: a device that allows wireless­equipped computers and other devices to communicate with a wired network. Also used to expand the range of a wireless network
infrastructure: a wireless network that is bridged to a wired network via 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.

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.
switch: a data switch that connects computing devices to host computers, allowing a large number of devices to share a limited number of ports
