Wireless-N Home Router
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-N Home Router. The Wireless-N Home Router will allow you to
network wirelessly better than ever, sharing Internet access, files and fun, easily and securely and with a greater
range of up to four times farther than standard Wireless-G.
How does the Wireless-N Home Router do all of this? A router is a device that allows access to an Internet
connection over a network. With the Wireless-N Home Router, this access can be shared over the four switched
ports or via the wireless broadcast.
Use the PSK2 standard to secure your wireless network while the whole network is protected through a Stateful
Packet Inspection (SPI) firewall and Network Address Translation (NAT) technology. The Router also offers VPN
passthrough and other features, which can be configured through the easy-to-use, browser-based utility.
The incredible speed of Wireless-N makes it ideal for media-centric applications like streaming video and Voice
over IP (VoIP) telephony, so your network can handle multiple data streams at the same time, with no degradation
in performance.
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 on a wired network create a LAN, or Local Area Network. They are connected with Ethernet cables, which is
why the network is called "wired".
PCs equipped with wireless cards or adapters can communicate without cumbersome cables. By sharing the
same wireless settings, within their transmission radius, they form a wireless network. This is sometimes called
a WLAN, or Wireless Local Area Network. The Wireless-N Home Router bridges wireless and wired networks,
allowing them to communicate with each other.
Linksys recommends using the Setup Wizard on the Setup CD-ROM for first-time installation of the Router. If you
do not wish to run the Setup Wizard, then use the instructions in this Guide to help you connect the Router and
configure it. These instructions should be all you need to get the most out of the Wireless-N Home Router.
