Wireless-G Broadband Router with 2 Phone Ports
Chapter 1: Introduction
Welcome
Thank you for choosing the Wireless-G Broadband Router with 2 Phone Ports. This Router can direct and control
communications for your wiredand wireless networks, sharing Internet access, files andfun, easily and securely.
Plus, after you have set up your Internet phone service, make phone or fax calls using your Internet connection.
How does the Router do all of this? A router is a device that allows access to an Internet connection over a
network. With the Wireless-G Broadband Router, this accesscan be shared over the four switched ports or via the
wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for Wireless-G. In addition, the WPA
standard provides greater security opportunities while the whole network is protected through NAT technology.
Full configurability, including these security features, are accessed through the easy-to-use, web-based utility.
But what does all of this mean?
Networks are useful tools for sharing Internet access and computer resources. Multiple computers can share
Internet access, so you don’t need more than one high-speed Internet connection. After you set up your Internet
phoneservice, you canalso make Internet phone or fax calls,even while you’resurfingtheInternet. Plus, youcan
accessoneprinter from different computers andaccessdatalocated on another computer’sharddrive.Networks
are even used for playing multiplayer video games. All the while, the Router protects your networks from
unauthorized and unwelcome users. So, networks not only are useful in homes and offices, but also can 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, which is sometimes
calleda Wireless Local Area Network(WLAN).The Router bridges wirelessnetworks of both 802.11band 802.11g
standards and wired networks, allowing them to communicate with each other.
To create your network, install and set up the Router. To guide you through the process, Linksys strongly
recommends that you runthe SetupWizard onthe Setup CD-ROM.Ifyoupreferto manually setup the Router, use
the instructions in the Quick Installation or this User Guide to help you. These instructions should be all you need
to get the most out of the Wireless-G Broadband Router.

Chapter 2: Planning Your Wireless Network
Network Topology
Wireless-G Broadband Router with 2 Phone Ports
Chapter 2: Planning Your Wireless Network
Network Topology
A Wireless Local Area Network (WLAN) is exactly like a regular Local Area Network (LAN), except that each
computer in the WLAN uses a wireless device to connect to the network. Computers in a WLAN share the same
frequency channel and SSID, which is an identification name shared by the wireless devices belonging to the
same wireless network.
Ad-Hoc versus Infrastructure Mode
Unlike wired networks, wireless networks have two different modes in which they may be set up: infrastructure
and ad-hoc. An infrastructure configuration is a WLAN and wired LAN communicating to each other through an
access point. An ad-hoc configuration is wireless-equipped computers communicating directly with each other.
Choosing between these two modes depends on whether or not the wireless network needs to share data or
peripherals with a wired network or not.
If the computers on the wireless network need to be accessible by a wired network or need to share a peripheral,
such as a printer, with the wired network computers, the wireless network should be set up in Infrastructure
mode. The basis of Infrastructure mode centers around an access point or wireless router, such as the
Wireless-G Broadband Router with 2 Phone Ports, which serves as the main point of communications in a
wireless network. The Router transmits data to PCs equipped with wireless network adapters, which can roam
within a certain radial range of the Router. You can arrange the Router and multiple access points to work in
succession to extend the roaming range, and you can set up your wireless network to communicate with your
Ethernet hardware as well.
If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wireless-
equipped computers is limited by the distance and interference directly between them.
infrastructure: a wireless network
that is bridged to a wired network via
an access point
ssid: your wireless network’s name
ad-hoc: a group of wireless devices
communicating directly to each other
(peer-to-peer) without the use of an
access point
access point: a device that allows wireless-
equipped computers and other devices to
communicate with a wired network. Also used
to expand the range of a wireless network
adapter: a device that adds
network functionality to your PC
ethernet: IEEE standard network protocol that
specifies how data is placed on and retrieved
from a common transmission medium
network: a series of computers or devices
connected for the purpose of data sharing,
storage, and/or transmission between users
