Welcome

Wireless-G Home Router

Chapter 1: Introduction

Welcome

Thank you for choosing the Linksys Wireless-G Home Router. The Wireless-G Home Router will allow you to

network wirelessly better than ever, sharing Internet access, files and fun, easily and securely.

How does the Wireless-G Home Router do all of this? A router is a device that allows access to an Internet

connection over a network. With the Wireless-G Home Router, this access can be shared over the four switched

ports or via the wireless broadcast at up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G.

Wi-Fi Protected Access™ 2 (WPA2) protects your data and privacy with up to 128-bit industrial-strength

encryption.

The Router can serve as a DHCP Server, has a powerful SPI firewall to protect your PCs against

intruders and most known Internet attacks, supports VPN pass-through, and can be configured to filter internal

users' access to the Internet.

Advanced configuration is a snap with the web browser-based interface.

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-G Home Router bridges wireless networks of both 802.11b

and 802.11g standards and wired networks, allowing them to communicate with each other.

With your networks all connected, wired, wireless, and the Internet, you can now share files and Internet

access—and even play games. All the while, the Wireless-G Home Router protects your networks from

unauthorized and unwelcome users.

Linksys recommends using the Setup CD-ROM for first-time installation of the Router. If you do not wish to run

the Setup Wizard on the Setup CD-ROM, then use the instructions in this Guide to help you connect the

Wireless-G Home Router, set it up, and configure it to bridge your different networks. These instructions should

be all you need to get the most out of the Wireless-G Home Router.

lan

(local area network): The computers and

networking products that make up the network in

your home or office.

nat

(network address translation): NAT technology

translates IP addresses of a local area network to a

different IP address for the Internet.

wpa

(wi-fi protected access): a wireless security

protocol using TKIP (Temporal Key Integrity Protocol)

encryption, which can be used in conjunction with a

RADIUS server.

spi

(stateful packet inspection)

firewall

: a technology

that inspects incoming packets of information before

allowing them to enter the network.

firewall

: Security measures that protect the

resources of a local network from intruders.
