Wireless-G Notebook Adapter

Chapter1:Introduction

Welcome

Thank you for choosing the Wireless-G Notebook Adapter. 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 notebook's PC Card slot and enjoy network access with your notebook computer, while

retaining true mobility.

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 up to 128-bit encryption.

You'll also be able to connect with any of the growing number of public wireless hotspots springing up in coffee

shops, airport lounges, hotels and convention centers. And as those hotspots upgrade to the new high-speed

Wireless-G standard, you'll be ready to take advantage of the increased speeds.

Get connected to current-standard 802.11b networks today, and be prepared for the future with the Wireless-G

Notebook Adapter from Linksys.

802.11b: a wireless networking standard that

specifies a maximum data transfer rate of 11Mbps

and an operating frequency of 2.4GHz.

adapter: a device that adds network functionality

to your PC.

network: a series of computers or devices

connected for the purpose of data sharing,

storage, and/or transmission between users.

802.11g a wireless networking standard that

specifies a maximum data transfer rate of 54Mbps

Network Topology

Wireless-G Notebook 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
