Wireless-G Broadband Router with 2 Phone Ports
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-G Broadband Router. The 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 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 Wireless-G Broadband Router, this access can be shared over the three
switched ports or via the wireless broadcast at either up to 11Mbps for Wireless-B or up to 54Mbps for WirelessG. In addition, the WPA standard provides greater security opportunities while the whole network is protected
through NAT technology. All of these security features, as well as full configurability, are accessed through the
easy-to-use browser-based utility.
But what does all of this mean?
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
nat (network address translation): NAT
technology translated IP addresses of a
local area network to a different IP address
for the Internet
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 babyTEL
account, you can also use your Internet access to make phone calls, even while you’re surfing the Internet.
Plus, 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 not only are useful in homes
and offices, but also can be fun.
mbps: one million bits per second; a unit of
measurement for data transmission
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”.
lan (local area network): the computers and
networking products that make up the network
in your home or office
browser: an application program that
provides a way to look at and interact with all
the information on the World Wide Web
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 Broadband Router bridges wireless networks of both
802.11b and 802.11g standards and wired networks, allowing them to communicate with each other.
ethernet: an IEEE standard network protocol that
specifies how data is placed on and retrieved from
a common transmission medium
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 Broadband Router protects your networks from
unauthorized and unwelcome users.
802.11b: an IEEE wireless networking standard
that specifies a maximum data transfer rate of
11Mbps and an operating frequency of 2.4GHz
To create your network, install and set up the Router. To guide you through the process, Linksys strongly
recommends that you run the Setup Wizard on the Setup CD-ROM. If you prefer to manually set up 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.
802.11g: an IEEE wireless networking standard
that specifies a maximum data transfer rate of
54Mbps, an operating frequency of 2.4GHz, and
backward compatibility with 802.11b devices

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 wirelessequipped computers is limited by the distance and interference directly between them.
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: 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

The Wireless Tab - Advanced Wireless Settings
This tab is used to set up the Router’s advanced wireless functions. These settings should only be adjusted by an
expert administrator as incorrect settings can reduce wireless performance.
Basic Rate. The Basic Rate setting is not actually one rate of transmission but a series of rates at which the
Router can transmit. The Router will advertise its Basic Rate to the other wireless devices in your network, so
they know which rates will be used. The Router will also advertise that it will automatically select the best rate
for transmission. The default setting is Default, when the Router can transmit at all standard wireless rates
(1-2Mbps, 5.5Mbps, 11Mbps, 18Mbps, and 24Mbps). Other options are 1-2Mbps, for use with older wireless
technology, and All, when the Router can transmit at all wireless rates. The Basic Rate is not the actual rate of
data transmission. If you want to specify the Router’s rate of data transmission, configure the Transmission Rate
setting.
Figure 5-20: Wireless Tab - Advanced Wireless Settings
Control Tx Rate. The rate of data transmission should be set depending on the speed of your wireless network.
You can select from a range of transmission speeds, or you can select Auto to have the Router automatically use
the fastest possible data rate and enable the Auto-Fallback feature. Auto-Fallback will negotiate the best possible
connection speed between the Router and a wireless client. The default value is Auto.
Preamble Type. The preamble defines the length of the CRC block for communication between the Router and
the roaming Network Card. (High network traffic areas should use the shorter preamble type.) Select the
appropriate preamble type, Long Preamble (default) or Short Preamble.
Authentication Type. The default is set to Auto, which allows either Open System or Shared Key authentication
to be used. With Open System authentication, the sender and the recipient do NOT use a WEP key for
authentication. With Shared Key authentication, the sender and recipient use a WEP key for authentication.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should remain disabled unless you are having
severe problems with your Wireless-G products. If these products are not able to transmit to the Router in an
environment with heavy 802.11b traffic, then enable CTS Protection Mode. This function boosts the Router’s
ability to catch all Wireless-G transmissions but will significantly decrease performance.
cts (clear to send): a signal sent by a wireless
device, signifying that it is ready to receive data
Beacon Interval. The default value is 100. Enter a value between 1 and 65,535 milliseconds. The Beacon Interval
value indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router to synchronize
the wireless network.
beacon interval: data transmitted on your wireless
network that keeps the network synchronized
DTIM Interval. This value, between 1 and 255, indicates the interval of the Delivery Traffic Indication Message
(DTIM). A DTIM field is a countdown field informing clients of the next window for listening to broadcast and
multicast messages. When the Router has buffered broadcast or multicast messages for associated clients, it
sends the next DTIM with a DTIM Interval value. Its clients hear the beacons and awaken to receive the broadcast
and multicast messages. The default value is 1.
dtim: a message included in data packets
that can increase wireless efficiency.

Fragmentation Threshold. This value specifies the maximum size for a packet before data is fragmented into
multiple packets. If you experience a high packet error rate, you may slightly increase the Fragmentation
Threshold. Setting the Fragmentation Threshold too low may result in poor network performance. Only minor
reduction of the default value is recommended. In most cases, it should remain at its default value of 2346.
fragmentation: breaking a packet into smaller units
when transmitting over a network medium that
cannot support the original size of the packet.
RTS Threshold. Should you encounter inconsistent data flow, only minor reduction of the default value, 2347, is
recommended. If a network packet is smaller than the preset RTS threshold size, the RTS/CTS mechanism will
not be enabled. The Router sends Request to Send (RTS) frames to a particular receiving station and negotiates
the sending of a data frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS)
frame to acknowledge the right to begin transmission. The RTS Threshold value should remain at its default value
of 2347.

The Applications & Gaming Tab - Port Range Forwarding
When you click the Applications & Gaming tab, you will see the Port Range Forwarding screen. Port Range
Forwarding sets up public services on your network, such as web servers, ftp servers, e-mail servers, or other
specialized Internet applications. (Specialized Internet applications are any applications that use Internet access
to perform functions such as videoconferencing or online gaming. Some Internet applications may not require
any forwarding.) When users send this type of request to your network via the Internet, the Router will forward
those requests to the appropriate PC.
Before using forwarding, you should assign a static IP address to the designated PC.
If you need to forward all ports to one PC, click the DMZ tab.

The UPnP Forwarding screen displays preset application settings as well as options to customize port services for
other applications.
UPnP Forwarding
Application. Ten applications are preset. For custom applications, enter the name of your application in one of
the available fields.
The preset applications are among the most widely used Internet applications. They include the following:
FTP (File Transfer Protocol). A protocol used to transfer files over a TCP/IP network (Internet, UNIX, etc.). For
example, after developing the HTML pages for a website on a local machine, they are typically uploaded to the
web server using FTP.
Telnet. A terminal emulation protocol commonly used on Internet and TCP/IP-based networks. It allows a user at
a terminal or computer to log onto a remote device and run a program.
SMTP (Simple Mail Transfer Protocol). The standard e-mail protocol on the Internet. It is a TCP/IP protocol that
defines the message format and the message transfer agent (MTA), which stores and forwards the mail.
Figure 5-29: Applications & Gaming Tab UPnP Forwarding
DNS (Domain Name System). The way that Internet domain names are located and translated into IP addresses. A
domain name is a meaningful and easy-to-remember “handle” for an Internet address.
TFTP (Trivial File Transfer Protocol). A version of the TCP/IP FTP protocol that has no directory or password
capability.
Finger. A UNIX command widely used on the Internet to find out information about a particular user, such as a
telephone number, whether the user is currently logged on, and the last time the user was logged on. The person
being “fingered” must have placed his or her profile on the system in order for the information to be available.
Fingering requires entering the full user@domain address.
HTTP (HyperText Transport Protocol). The communications protocol used to connect to servers on the World Wide
Web. Its primary function is to establish a connection with a web server and transmit HTML pages to the client
web browser.
POP3 (Post Office Protocol 3). A standard mail server commonly used on the Internet. It provides a message store
that holds incoming e-mail until users log on and download it. POP3 is a simple system with little selectivity. All
pending messages and attachments are downloaded at the same time. POP3 uses the SMTP messaging protocol.
Chapter 5: Configuring the Wireless-G Broadband Router with 2 Phone Ports
The Applications & Gaming Tab - UPnP Forwarding
39
Wireless-G Broadband Router with 2 Phone Ports
NNTP (Network News Transfer Protocol). The protocol used to connect to Usenet groups on the Internet. Usenet
newsreaders support the NNTP protocol.
SNMP (Simple Network Management Protocol). A widely used network monitoring and control protocol. Data is
passed from SNMP agents, which are hardware and/or software processes reporting activity in each network
device (hub, router, bridge, etc.) to the workstation console used to oversee the network. The agents return
information contained in a MIB (Management Information Base), which is a data structure that defines what is
obtainable from the device and what can be controlled (turned off, on, etc.).
Ext. Port. Enter the number of the external port used by the server in the Ext. Port column. Check with the
Internet application documentation for more information.
TCP or UDP. Select the protocol UDP or TCP for each application. You cannot select both protocols.
Int. Port. Enter the number of the internal port used by the server in the Int. Port column. Check with the Internet
application software documentation for more information.
IP Address. Enter the IP address of the server that you want the Internet users to be able to access. To find the IP
address, go to “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter.”
Enabled. Check the Enabled box to enable the service you have defined. UPnP Forwarding will not function if the

The Applications & Gaming Tab - DMZ
The DMZ screen allows one local user to be exposed to the Internet for use of a special-purpose service such as
Internet gaming and videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port
Range Forwarding is more secure because it only opens the ports you want to have opened, while DMZ hosting
opens all the ports of one computer, exposing the computer to the Internet.
Any PC whose port is being forwarded must have its DHCP client function disabled and should have a new static
IP address assigned to it because its IP address may change when using the DHCP function.

of your Ethernet adapter onto the Router, see the System section of “Chapter 5: Configuring the
Wireless-G Broadband Router with 2 Phone Ports” for details.
• Make sure you are using the right Internet connection settings. Contact your ISP to see if your Internet
connection type is DHCP, Static IP Address, or PPPoE (commonly used by DSL consumers). Please refer to
the Setup section of “Chapter 5: Configuring the Wireless-G Broadband Router with 2 Phone Ports” for
details on Internet connection settings.
• Make sure you have the right cable. Check to see if the Internet column has a solidly lit Link/Act LED.
• Make sure the cable connecting from your cable or DSL modem is connected to the Router’s Internet port.
Verify that the Status page of the Router’s web-based utility shows a valid IP address from your ISP.
• Turn off the computer, Router, and cable/DSL modem. Wait 30 seconds, and then turn on the Router,
cable/DSL modem, and computer. Check the Status tab of the Router’s web-based utility to see if you get
an IP address.
7. I am not able to access the Setup page of the Router’s web-based utility.
• Refer to “Problem #5, I want to test my Internet connection” to verify that your computer is properly
connected to the Router.
• Refer to “Appendix E: Finding the MAC Address and IP address for Your Ethernet Adapter” to verify that
your computer has an IP Address, Subnet Mask, Gateway, and DNS.
• Set a static IP address on your system; refer to “Problem #4: I need to set a static IP address.”
• Refer to “Problem #12: I need to remove the proxy settings or the dial-up pop-up window (for PPPoE
users).”
8. I need to set up a server behind my Router and make it available to the public.
To use a server like a web, ftp, or mail server, you need to know the respective port numbers they are using.
For example, port 80 (HTTP) is used for web; port 21 (FTP) is used for FTP, and port 25 (SMTP outgoing) and
port 110 (POP3 incoming) are used for the mail server. You can get more information by viewing the
documentation provided with the server you installed.
Follow these steps to set up port forwarding through the Router’s web-based utility. We will be setting up
web, ftp, and mail servers.

1. Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Forwarding tab.
2. Enter any name you want to use for the Customized Application.
3. Enter the External Port range of the service you are using. For example, if you have a web server, you
would enter the range 80 to 80.
4. Check the protocol you will be using, TCP and/or UDP.
5. Enter the IP address of the PC or network device that you want the port server to go to. For example,
if the web server’s Ethernet adapter IP address is 192.168.1.100, you would enter 100 in the field
provided. Check “Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for
details on getting an IP address.

When you have completed the configuration, click the Save Settings button.
9. I need to set up online game hosting or use other Internet applications.
If you want to play online games or use Internet applications, most will work without doing any port
forwarding or DMZ hosting. There may be cases when you want to host an online game or Internet
application. This would require you to set up the Router to deliver incoming packets or data to a specific
computer. This also applies to the Internet applications you are using. The best way to get the information on
what port services to use is to go to the website of the online game or application you want to use. Follow
these steps to set up online game hosting or use a certain Internet application:
1. Access the Router’s web interface by going to http://192.168.1.1 or the IP address of the Router. Go to
the Applications & Gaming => Port Forwarding tab.
2. Enter any name you want to use for the Customized Application.
3. Enter the External Port range of the service you are using. For example, if you want to host Unreal
Tournament (UT), you would enter the range 7777 to 27900.
4. Check the protocol you will be using, TCP and/or UDP.
5. Enter the IP address of the PC or network device that you want the port server to go to. For example,

When you have completed the configuration, click the Save Settings button.
10. I can’t get the Internet game, server, or application to work.
If you are having difficulties getting any Internet game, server, or application to function properly, consider
exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an
application requires too many ports or when you are not sure which port services to use. Make sure you
disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority
over DMZ hosting. (In other words, data that enters the Router will be checked first by the forwarding
settings. If the port number that the data enters from does not have port forwarding, then the Router will send
the data to whichever PC or network device you set for DMZ hosting.)
Follow these steps to set DMZ hosting:
1. Access the Router’s web-based utility by going to http://192.168.1.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Forwarding tab.
2. Disable or remove the entries you have entered for forwarding. Keep this information in case you
want to use it at a later time.
3. Go to the Applications & Gaming => DMZ tab.
4. Select Enable next to DMZ. In the DMZ Host IP Address field, enter the IP address of the computer you
want exposed to the Internet. This will bypass the NAT technology for that computer. Please refer to
“Appendix E: Finding the MAC Address and IP Address for Your Ethernet Adapter” for details on
getting an IP address.
5. Once completed with the configuration, click the Save Settings button.

Appendix A: Troubleshooting
Frequently Asked Questions
61
Wireless-G Broadband Router with 2 Phone Ports
What is the maximum number of IP addresses that the Router will support?
The Router will support up to 253 IP addresses.
Is IPSec Pass-Through supported by the Router?
Yes, it is a built-in feature that the Router automatically enables.
Where is the Router installed on the network?
In a typical environment, the Router is installed between the cable/DSL modem and the LAN. Plug the Router into
the cable/DSL modem’s Ethernet port.
Does the Router support IPX or AppleTalk?
No. TCP/IP is the only protocol standard for the Internet and has become the global standard for communications.
IPX, a NetWare communications protocol used only to route messages from one node to another, and AppleTalk,
a communications protocol used on Apple and Macintosh networks, can be used for LAN to LAN connections, but
those protocols cannot connect from the Internet to a LAN.
Does the Internet connection of the Router support 100Mbps Ethernet?
The Router’s current hardware design supports up to 100Mbps Ethernet on its Internet port; however, the Internet
connection speed will vary depending on the speed of your broadband connection. The Router also supports
100Mbps over the auto-sensing Fast Ethernet 10/100 switch on the LAN side of the Router.
What is Network Address Translation and what is it used for?
Network Address Translation (NAT) translates multiple IP addresses on the private LAN to one public address that
is sent out to the Internet. This adds a level of security since the address of a PC connected to the private LAN is
never transmitted on the Internet. Furthermore, NAT allows the Router to be used with low cost Internet
accounts, such as DSL or cable modems, when only one TCP/IP address is provided by the ISP. The user may
have many private addresses behind this single address provided by the ISP.
Does the Router support any operating system other than Windows 98SE, Windows Millennium,
Windows 2000, or Windows XP?
Yes, but Linksys does not, at this time, provide technical support for setup, configuration or troubleshooting of
any non-Windows operating systems.
Does the Router support ICQ send file?
Yes, with the following fix: click ICQ menu -> preference -> connections tab->, and check I am behind a firewall
or proxy. Then set the firewall time-out to 80 seconds in the firewall setting. The Internet user can then send a file
to a user behind the Router.
Appendix A: Troubleshooting
Frequently Asked Questions
62
Wireless-G Broadband Router with 2 Phone Ports
I set up an Unreal Tournament Server, but others on the LAN cannot join. What do I need to do?
If you have a dedicated Unreal Tournament server running, you need to create a static IP for each of the LAN
computers and forward ports 7777, 7778, 7779, 7780, 7781, and 27900 to the IP address of the server. You can
also use a port forwarding range of 7777 ~ 27900. If you want to use the UT Server Admin, forward another port.
(Port 8080 usually works well but is used for remote admin. You may have to disable this.) Then in the
[UWeb.WebServer] section of the server.ini file, set the ListenPort to 8080 (to match the mapped port above) and
ServerName to the IP assigned to the Router from your ISP.
Can multiple gamers on the LAN get on one game server and play simultaneously with just one public IP
address?
It depends on which network game or what kind of game server you are using. For example, Unreal Tournament
supports multi-login with one public IP.
How do I get Half-Life: Team Fortress to work with the Router?
The default client port for Half-Life is 27005. The computers on your LAN need to have “+clientport 2700x”
added to the HL shortcut command line; the x would be 6, 7, 8, and on up. This lets multiple computers connect
to the same server. One problem: Version 1.0.1.6 won’t let multiple computers with the same CD key connect at
the same time, even if on the same LAN (not a problem with 1.0.1.3). As far as hosting games, the HL server does
not need to be in the DMZ. Just forward port 27015 to the local IP address of the server computer.
How can I block corrupted FTP downloads?
If you are experiencing corrupted files when you download a file with your FTP client, try using another FTP
program.
The web page hangs; downloads are corrupt, or nothing but junk characters are being displayed on the
screen. What do I need to do?
Force your Ethernet adapter to 10Mbps or half duplex mode, and turn off the “Auto-negotiate” feature of your
Ethernet adapter as a temporary measure. (Please look at the Network Control Panel in your Ethernet adapter’s
Advanced Properties tab.) Make sure that your proxy setting is disabled in the browser. Check our website at
www.linksys.com for more information.
If all else fails in the installation, what can I do?
Reboot the system. Please refer to the rebooting procedures in the FAQ section of the babyTEL website.
How will I be notified of new Router firmware upgrades?
babyTEL upgrades the firmware remotely and automatically, when needed. babyTEL will notify you by email
prior to an update.

Frequently Asked Questions
65
Wireless-G Broadband Router with 2 Phone Ports
What is ad-hoc mode?
When a wireless network is set to ad-hoc mode, the wireless-equipped computers are configured to
communicate directly with each other. The ad-hoc wireless network will not communicate with any wired
network.
What is infrastructure mode?
When a wireless network is set to infrastructure mode, the wireless network is configured to communicate with
a wired network through a wireless access point.
What is roaming?
Roaming is the ability of a portable computer user to communicate continuously while moving freely throughout
an area greater than that covered by a single access point. Before using the roaming function, the workstation
must make sure that it is the same channel number with the access point of dedicated coverage area.
To achieve true seamless connectivity, the wireless LAN must incorporate a number of different functions. Each
node and access point, for example, must always acknowledge receipt of each message. Each node must
maintain contact with the wireless network even when not actually transmitting data. Achieving these functions
simultaneously requires a dynamic RF networking technology that links access points and nodes. In such a
system, the user’s end node undertakes a search for the best possible access to the system. First, it evaluates
such factors as signal strength and quality, as well as the message load currently being carried by each access
point and the distance of each access point to the wired backbone. Based on that information, the node next
selects the right access point and registers its address. Communications between end node and host computer
can then be transmitted up and down the backbone.
As the user moves on, the end node’s RF transmitter regularly checks the system to determine whether it is in
touch with the original access point or whether it should seek a new one. When a node no longer receives
acknowledgment from its original access point, it undertakes a new search. Upon finding a new access point, it
then re-registers, and the communication process continues.
What is ISM band?
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed use in the ISM
(Industrial, Scientific and Medical) band. Spectrum in the vicinity of 2.4 GHz, in particular, is being made available
worldwide. This presents a truly revolutionary opportunity to place convenient high-speed wireless capabilities in
the hands of users around the globe.
What is Spread Spectrum?
Spread Spectrum technology is a wideband radio frequency technique developed by the military for use in
reliable, secure, mission-critical communications systems. It is designed to trade off bandwidth efficiency for
reliability, integrity, and security. In other words, more bandwidth is consumed than in the case of narrowband
transmission, but the trade-off produces a signal that is, in effect, louder and thus easier to detect, provided that
Appendix A: Troubleshooting
Frequently Asked Questions
66
Wireless-G Broadband Router with 2 Phone Ports
the receiver knows the parameters of the spread-spectrum signal being broadcast. If a receiver is not tuned to
the right frequency, a spread-spectrum signal looks like background noise. There are two main alternatives,
Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
What is DSSS? What is FHSS? And what are their differences?
Frequency-Hopping Spread-Spectrum (FHSS) uses a narrowband carrier that changes frequency in a pattern that
is known to both transmitter and receiver. Properly synchronized, the net effect is to maintain a single logical
channel. To an unintended receiver, FHSS appears to be short-duration impulse noise. Direct-Sequence SpreadSpectrum (DSSS) generates a redundant bit pattern for each bit to be transmitted. This bit pattern is called a chip
(or chipping code). The longer the chip, the greater the probability that the original data can be recovered. Even if
one or more bits in the chip are damaged during transmission, statistical techniques embedded in the radio can
recover the original data without the need for retransmission. To an unintended receiver, DSSS appears as low
power wideband noise and is rejected (ignored) by most narrowband receivers.
What is WEP?
WEP is Wired Equivalent Privacy, a data privacy mechanism based on a shared key algorithm, as described in the
IEEE 802.11 standard.
What is WPA?
WPA is Wi-Fi Protected Access, a wireless security protocol that can be used in conjunction with a RADIUS server.
What is a MAC Address?
The Media Access Control (MAC) address is a unique number assigned by the manufacturer to any Ethernet
networking device, such as a network adapter, that allows the network to identify it at the hardware level. For all
practical purposes, this number is usually permanent. Unlike IP addresses, which can change every time a
computer logs onto the network, the MAC address of a device stays the same, making it a valuable identifier for
the network.
How do I reset the Router?
Press the Reset button on the back panel for about five seconds. This will reset the Router to its default settings.
How do I resolve issues with signal loss?
There is no way to know the exact range of your wireless network without testing. Every obstacle placed between
the Router and a wireless PC will create signal loss. Lead glass, metal, concrete floors, water and walls will
inhibit the signal and reduce range. Start with the Router and your wireless PC in the same room and move it
away in small increments to determine the maximum range in your environment.
You may also try using different channels, as this may eliminate interference affecting only one channel.

I have excellent signal strength, but I cannot see my network.
WEP is probably enabled on the Router, but not on your wireless adapter (or vice versa). Verify that the same WEP
keys and levels (64 or 128) are being used on all nodes of your wireless network.
How many channels/frequencies are available with the Router?
There are eleven available channels, ranging from 1 to 11 (in North America).

point’s documentation for more information.
7. Change the WEP encryption keys periodically.
For information on implementing these security features, refer to “Chapter 6: Configuring the Wireless-G
Broadband Router.”
Security Threats Facing Wireless Networks
Wireless networks are easy to find. Hackers know that in order to join a wireless network, wireless networking
products first listen for “beacon messages”. These messages can be easily decrypted and contain much of the
network’s information, such as the network’s SSID (Service Set Identifier). Here are the steps you can take:
Change the administrator’s password regularly. With every wireless networking device you use, keep in
mind that network settings (SSID, WEP keys, etc.) are stored in its firmware. Your network administrator is the
only person who can change network settings. If a hacker gets a hold of the administrator’s password, he, too,
can change those settings. So, make it harder for a hacker to get that information. Change the administrator’s
password regularly.
Appendix B: Wireless Security

SSID. There are several things to keep in mind about the SSID:
1. Disable Broadcast
2. Make it unique
3. Change it often
Most wireless networking devices will give you the option of broadcasting the SSID. While this option may be
more convenient, it allows anyone to log into your wireless network. This includes hackers. So, don’t broadcast
the SSID.
Wireless networking products come with a default SSID set by the factory. (The Linksys default SSID is “linksys”.)
Hackers know these defaults and can check these against your network. Change your SSID to something unique
and not something related to your company or the networking products you use.
Change your SSID regularly so that any hackers who have gained access to your wireless network will have to
start from the beginning in trying to break in.
MAC Addresses. Enable MAC Address filtering. MAC Address filtering will allow you to provide access to only
those wireless nodes with certain MAC Addresses. This makes it harder for a hacker to access your network with
a random MAC Address.
WEP Encryption. Wired Equivalent Privacy (WEP) is often looked upon as a cure-all for wireless security
concerns. This is overstating WEP’s ability. Again, this can only provide enough security to make a hacker’s job
more difficult.
There are several ways that WEP can be maximized:
1. Use the highest level of encryption possible
2. Use “Shared Key” authentication
3. Change your WEP key regularly
Important: Always remember that each
device in your wireless network MUST use
the same encryption method and encryption
key or your wireless network will not function
properly.
WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. Two modes are
available: Pre-Shared Key and RADIUS. Pre-Shared Key gives you one encryption methods: TKIP (Temporal Key
Integrity Protocol), which utilizes a stronger encryption method and incorporates Message Integrity Code (MIC) to
provide protection against hackers.
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
70
Wireless-G Broadband Router with 2 Phone Ports
WPA Pre-Shared Key. If you do not have a RADIUS server, Select the type of algorithm, TKIP or AES, enter a
password in the Pre-Shared key field of 8-64 characters, and enter a Group Key Renewal period time
between 0 and 99,999 seconds, which instructs the Router or other device how often it should change the
encryption keys.
WPA RADIUS. WPA used in coordination with a RADIUS server. (This should only be used when a RADIUS
server is connected to the Router or other device.) First, select the type of WPA algorithm, TKIP or AES. Enter
the RADIUS server’s IP Address and port number, along with a key shared between the device and the server.
Last, enter a Group Key Renewal period, which instructs the device how often it should change the encryption
keys.
Implementing encryption may have a negative impact on your network’s performance, but if you are transmitting
sensitive data over your network, encryption should be used.
These security recommendations should help keep your mind at ease while you are enjoying the most flexible
and convenient technology Linksys has to offer.
