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.

Network Topology
Wireless-G Home Router
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 a wireless router or an access point, such as the
Wireless-G Home Router, 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 wirelessequipped
computers is limited by the distance and interference directly between them.
Network Layout
The Wireless-G Home Router has been specifically designed for use with both your 802.11b and 802.11g
products. Now, products using these standards can communicate with each other.
infrastructure: a wireless network that is bridged
to a wired network via an access point.
ssid (service set identifier): your wireless network’s name.
ad-hoc: a group of wireless devices
communicating directly to each other (peer-topeer)
without the use of an access point.

Wireless-G Home Router
The Wireless-G Home Router is compatible with all 802.11b and 802.11g adapters, such as the Notebook
Adapters (WPC54G, WPC11) for your laptop computers, PCI Adapter (WMP54G, WMP11) for your desktop PC, and
USB Adapter (WUSB54G, WUSB11) when you want to enjoy USB connectivity. The Home Router will also
communicate with the Wireless PrintServer (WPS54G) and Wireless Ethernet Bridges (WET54G, WET11).
When you wish to connect your wireless network with your wired network, you can use the Wireless-G Home
Router’s four LAN ports. To add more ports, any of the Wireless-G Home Router's LAN ports can be connected to
any of Linksys's switches (such as the SD205 or SD208).
With these, and many other, Linksys products, your networking options are limitless. Go to the Linksys website at

The Back Panel
The Router's ports, where the cables are connected, are located on the back panel.
Ethernet 1, 2, 3, 4 These ports (1, 2, 3, 4) connect the Router to your networked PCs and other Ethernet
network devices.
Internet The Internet port is where you will connect your broadband Internet connection.
Reset Button There are two ways to reset the Router's factory defaults. Either press the Reset Button, for
approximately five seconds, or restore the defaults from the Administration tab - Factory
Defaults in the Router's Web-based Utility.
Power The Power port is where you will connect the power adapter.
IMPORTANT: Resetting the Router will erase
all of your settings (Internet connection,
wireless security, and other settings) and
replace them with the factory defaults. Do not
reset the Router if you want to retain these
settings.

The Front Panel
The Router’s LEDs are located on the front panel.
Power Green. The Power LED lights up and will stay on while the Router is powered on. When the
Router goes through its self-diagnostic mode during every boot-up, this LED will flash. When
the diagnostic is complete, the LED will be solidly lit.
1, 2, 3, 4 Green. These numbered LEDs, corresponding with the numbered ports on the Router’s back
panel, serve two purposes. If the LED is continuously lit, the Router is successfully connected
to a device through that port. A flashing LED indicates network activity over that port.
Wireless Green. The Wireless LED lights up whenever there is a successful wireless connection. If the
LED is flashing, the Router is actively sending or receiving data over the network.
Internet Green. The Internet LED lights up when there is a connection made through the Internet port.
