1Chapter 1: IntroductionWelcomeWireless-N USB Network AdapterChapter 1: IntroductionWelcomeThank 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.What’s in this User Guide?This user guide covers the steps for setting up and using the Wireless-N USB Network Adapter.• Chapter 1: IntroductionThis chapter describes the Adapter’s applications and this User Guide.• Chapter 2: Planning Your Wireless NetworkThis chapter discusses a few of the basics about wireless networking.• Chapter 3: Getting to Know the Wireless-N USB Network AdapterThis chapter describes the physical features of the Adapter. 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 and an operating frequency of 2.4GHz.bit: a binary digit.encryption: encoding data transmitted in a network

3Chapter 2: Planning your Wireless NetworkNetwork TopologyWireless-N USB Network AdapterChapter 2: Planning your Wireless NetworkNetwork TopologyA 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.RoamingInfrastructure 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
4Chapter 2: Planning your Wireless NetworkNetwork LayoutWireless-N USB Network AdapterNetwork LayoutLinksys 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.
