Wireless-N USB Network Adapter

Chapter1:Introduction

Welcome

Thank you for choosing the Wireless-N USB Network Adapter. Setting up your network and your Wireless-N USB

Network Adapter is easier than ever. Just connect it to your PC's USB port and enjoy incredible high-speed

wireless network access, at unheard-of distances.

How does the Adapter do this? Like all wireless products, the Adapter 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

with Wireless-N, it has even better range and speed.

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 Adapter to your wireless network settings, step by

step. Use the instructions in this Guide to help you set up and connect the Adapter using the Setup Wizard. These

instructions should be all you need to get the most out of the Adapter.

Chapter 2: Planning your Wireless Network

Network Topology

Wireless-N USB Network 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

Chapter 2: Planning your Wireless Network

Network Layout

Wireless-N USB Network Adapter

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.
