Compact Wireless-G Broadband Router
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Compact Wireless-G Broadband Router. The Compact Wireless-G Broadband
Router will allow you to network wirelessly better than ever, sharing Internet access, files and fun, easily and
securely.
How does the Compact Wireless-G Broadband Router do all of this? A router is a device that allows access to an
Internet connection over a network. With the Compact Wireless-G Broadband Router, this access can 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 whole network is protected by NAT technology. For wireless networking, you also
have a choice of wireless security methods. Additional security features, as well as configuration options, are
accessible through the easy-to-use, browser-based utility.
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 Compact Wireless-G Broadband Router bridges wireless networks
of 802.11b, and 802.11g standards and wired networks, allowing them to communicate with each other.
With your wired and wireless networks connected to each other and the Internet, you can now share files and
Internet access—and even play games. All the while, the Compact Wireless-G Broadband 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
Compact Wireless-G Broadband 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 Compact Wireless-G Broadband 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.
network: a series of computers or devices
connected for the purpose of data sharing,
storage, and/or transmission between users.
ssid: your wireless network’s name.
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 Compact
Wireless-G Broadband 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.
ad-hoc: a group of wireless devices
communicating directly to each other
(peer-to-peer) without the use of an
access point.
infrastructure: a wireless network
that is bridged to a wired network via
an access point.
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.
access point: a device that allows wirelessequipped computers and other devices to
communicate with a wired network. Also used
to expand the range of a wireless network.

Optional Settings
Figure 5-6: PPTP Connection Type
Some of these settings may be required by your ISP. Verify with your ISP before making any changes.
Host Name and Domain Name. These fields allow you to supply a host and domain name for the Router. Some
ISPs, usually cable ISPs, require these names as identification. You may have to check with your ISP to see if your
broadband Internet service has been configured with a host and domain name. In most cases, leaving these
fields blank will work.
MTU. MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet
transmission. Select Manual if you want to manually enter the largest packet size that will be transmitted. The
recommended size, entered in the Size field, is 1500. You should leave this value in the 1200 to 1500 range. To
have the Router select the best MTU for your Internet connection, keep the default setting, Auto.
Network Setup
The Network Setup section changes the Router’s local network settings. Changes to the Router’s wireless
network settings are performed through the Wireless tab.
Router IP
IP Address and Subnet Mask. This shows both the Router’s IP Address and Subnet Mask, as seen by your
network. The default IP Address is 192.168.1.1, and the default Subnet Mask is 255.255.255.0. In most cases,
keeping the default values will work.

DHCP Server Settings
The settings allow you to configure the Router’s Dynamic Host Configuration Protocol (DHCP) server function. The
Router can be used as a DHCP server for your network. A DHCP server automatically assigns an IP address to
each computer on your network. If you choose to enable the Router’s DHCP server option, you must make sure
there is no other DHCP server on your network.
DHCP Server. DHCP is enabled by factory default. If you already have a DHCP server on your network, or you
don’t want a DHCP server, then select Disabled (no other DHCP features will be available).
Assign Static DHCP. Every time a PC reboots, it is assigned a new local IP address by the Router. If you want a PC
to be assigned the same IP address every time it reboots, then click the Assign Static IP button.
On the Static DHCP Client List screen, enter a client name, then enter the static local IP address in the Assign this
IP field, and enter the MAC address of the PC in the To this MAC field. Then click the Enabled checkbox. When you
have finished your entries, click the Save Settings button to save your changes. Click the Cancel Changes
button to cancel your changes. To exit this screen, click the Close button.
If you want to see a list of DHCP clients, click the DHCP Client Table button. On the DHCP Client Table screen, you
will see a list of DHCP clients with the following information: Client Names, Interfaces, IP Addresses, and MAC
Addresses. From the To Sort by drop-down menu, you can sort the table by Client Name, Interface, IP Address, or
MAC Address. To view the most up-to-date information, click the Refresh button. To exit this screen, click the
Close button.
Figure 5-7: Static DHCP Client List
Start IP Address. Enter a value for the DHCP server to start with when issuing IP addresses. Because the
Router’s default IP address is 192.168.1.1, the Starting IP Address must be 192.168.1.2 or greater, but smaller
than 192.168.1.254. The default Starting IP Address is 192.168.1.100.
Maximum Number of Users. Enter the maximum number of PCs that you want the DHCP server to assign IP
addresses to. This number cannot be greater than 253. The default is 50.
IP Address Range. The range of DHCP addresses is displayed here.
Client Lease Time. The Client Lease Time is the amount of time a network user will be allowed connection to the
Router with their current dynamic IP address. Enter the amount of time, in minutes, that the user will be “leased”
this dynamic IP address. After the time is up, the user will be automatically assigned a new dynamic IP address.
The default is 0 minutes, which means one day.
WINS. The Windows Internet Naming Service (WINS) manages each PC’s interaction with the Internet. If you use
a WINS server, enter that server’s IP Address here. Otherwise, leave this blank.

The Setup Tab - DDNS
dynamic ip address: a temporary IP
address assigned by a DHCP server.
The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain
name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other
server behind the Router.
Before you can use this feature, you need to sign up for DDNS service at one of two DDNS service providers, DynDNS.org or
TZO.com. If you do not want to use this feature, keep the default setting, Disable.
DDNS
DDNS Service. If your DDNS service is provided by DynDNS.org, then select DynDNS.org from the drop-down
menu. If your DDNS service is provided by TZO, then select TZO.com. The features available on the DDNS screen
will vary, depending on which DDNS service provider you use.
DynDNS.org
User Name, Password, and Host Name. Enter the User Name, Password, and Host Name of the account you
set up with DynDNS.org.
Internet IP Address. The Router’s current Internet IP Address is displayed here. Because it is dynamic, it will
change.
