Chapter 1: Introduction
Wireless-G Broadband Router with 2 Phone Ports
Welcome
Thank you for choosing the Linksys Wireless-G Broadband Router with 2 Phone Ports. This Router will allow you
to network wirelessly better than ever, sharing Internet access, files and fun, easily and securely. Plus, after you
have set up your babyTEL service, you can make phone or fax calls using your Internet connection.
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.
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 with 2 Phone Ports, 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 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.
nat (network address translation): NAT
technology translated IP addresses of a
local area network to a different IP
address for the Internet.
But what does all of this mean?
browser: an application program that
provides a way to look at and interact
with all the information on the World
Wide Web.
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 have set up your
babyTEL account, you can also use your Internet access to make Internet phone or fax 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. 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”.
Chapter 1: Introduction
Welcome
mbps: one million bits per second; a unit
of measurement for data transmission.
lan (local area network): the computers
and networking products that make up
the network in your home or office.
ethernet: an IEEE standard network
protocol that specifies how data is
placed on and retrieved from a common
transmission medium.
1
Wireless-G Broadband Router with 2 Phone Ports
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
called a Wireless Local Area Network (WLAN). The Router bridges wireless networks of both 802.11b and
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 run the Setup Wizard on the Setup CD-ROM. If you prefer to manually set up the Router,
use the instructions in this User Guide to help you. These instructions should be all you need to get the most out
of the Wireless-G Broadband Router with 2 Phone Ports.
What’s in this Guide?
This guide covers the basic steps for setting up a network with a router. After going through “Chapter 3: Getting
to Know the Router,” most users will only need to use the following chapters:

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.
Chapter 2: Planning Your Wireless Network
Network Topology
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.
ethernet: IEEE standard network
protocol that specifies how data is
placed on and retrieved from a common
transmission medium.
5
Wireless-G Broadband Router with 2 Phone Ports
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.
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.
Network Layout
The Wireless-G Broadband Router with 2 Phone Ports has been specifically designed for use with both your
802.11b and 802.11g products. It is compatible with all 802.11b and 802.11g adapters, such as the Notebook
Adapters for your laptop computers, PCI Adapters for your desktop PCs, and USB Adapters when you want to
enjoy USB connectivity. The Broadband Router will also communicate with the Wireless PrintServer and Wireless
Ethernet Bridges.

Preamble Type. The preamble defines the length of the CRC block for communication between the Router and
the roaming wireless adapters. (High network traffic areas should use the shorter preamble type.) Select the
appropriate preamble type for your network. If you are not sure which setting to select, then keep the default
setting, Long Preamble.
Authentication Type. The default is set to Auto, which allows Open System and Shared Key authentication. For
Open System authentication, the sender and the recipient do not use a WEP key for authentication but can use
WEP for data encryption. For Shared Key authentication, the sender and recipient use a WEP key for both
authentication and data encryption. To only allow Open System authentication, select Open. To only allow
Shared Key authentication, select Shared Key. In most cases, you should keep the default setting, Auto,
because some clients cannot be configured for Shared Key.
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode function boosts the Router’s ability to catch all
Wireless-G transmissions but will severely decrease performance. Keep the default setting, Auto, so the Router

Beacon Interval. 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. The default value is 100.
DTIM Interval. This 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 3.
dtim: a message included in data
packets that can increase wireless
efficiency.
Fragmentation Length. 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 Length 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. In most cases, keep the default value, 2347.

cached ones.
C. Click Tools. Click Internet Options. Click the Security tab. Click the Default level button. Make sure
the security level is Medium or lower. Then click the OK button.
3. I need to set a static IP address on a PC.
The Router, by default, assigns an IP address range of 192.168.15.100 to 192.168.15.150 using the DHCP
server on the Router. To set a static IP address, you can only use the ranges 192.168.15.2 to 192.168.15.99
and 192.168.15.151 to 192.168.15.254. Each PC or network device that uses TCP/IP must have a unique
address to identify itself in a network. If the IP address is not unique to a network, Windows will generate an
IP conflict error message. You can assign a static IP address to a PC by performing the following steps:
For Windows 98 and Millennium:
A. Click Start, Setting, and Control Panel. Double-click Network.
B. In The following network components are installed box, select the TCP/IP-> associated with your
Ethernet adapter. If you only have one Ethernet adapter installed, you will only see one TCP/IP line with
no association to an Ethernet adapter. Highlight it and click the Properties button.
C. In the TCP/IP properties window, select the IP address tab, and select Specify an IP address. Enter a
unique IP address that is not used by any other computer on the network connected to the Router. You
can only use an IP address in the ranges 192.168.15.2 to 192.168.15.99 and 192.168.15.151 to
192.168.15.254. Make sure that each IP address is unique for each PC or network device.
D. Click the Gateway tab, and in the New Gateway prompt, enter 192.168.15.1, which is the default IP
address of the Router. Click the Add button to accept the entry.
E. Click the DNS tab, and make sure the DNS Enabled option is selected. Enter the Host and Domain
names (e.g., John for Host and home for Domain). Enter the DNS entry provided by your ISP. If your ISP
has not provided the DNS IP address, contact your ISP to get that information or go to its website for the
information.

6. I am not able to access the Router’s Web-based Utility Setup page.
A. Refer to “Problem #4, I want to test my Internet connection” to verify that your computer is properly
connected to the Router.
B. Refer to “Appendix C: 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.
C. Set a static IP address on your system; refer to “Problem #3: I need to set a static IP address on a PC.”
D. Refer to “Problem #12: I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up
window.”
7. I can’t get my Virtual Private Network (VPN) to work through the Router.
Access the Router’s web interface by going to http://192.168.15.1 or the IP address of the Router, and go to
the Security => VPN Passthrough tab. Make sure you have IPsec passthrough and/or PPTP passthrough
enabled.
VPNs that use IPSec with the ESP (Encapsulation Security Payload known as protocol 50) authentication will
work fine. At least one IPSec session will work through the Router; however, simultaneous IPSec sessions
may be possible, depending on the specifics of your VPNs.
Appendix A: Troubleshooting
Common Problems and Solutions
59
Wireless-G Broadband Router with 2 Phone Ports
VPNs that use IPSec and AH (Authentication Header known as protocol 51) are incompatible with the Router.
AH has limitations due to occasional incompatibility with the NAT standard.
Change the IP address for the Router to another subnet to avoid a conflict between the VPN IP address and
your local IP address. For example, if your VPN server assigns an IP address 192.168.15.X (X is a number
from 1 to 254) and your local LAN IP address is 192.168.15.X (X is the same number used in the VPN IP
address), the Router will have difficulties routing information to the right location. If you change the Router’s
IP address to 192.168.2.1, that should solve the problem. Change the Router’s IP address through the Basic
Setup tab of the Web-based Utility. If you assigned a static IP address to any computer or network device on
the network, you need to change its IP address accordingly to 192.168.2.Y (Y being any number from 1 to
254). Note that each IP address must be unique within the network.
Your VPN may require port 500/UDP packets to be passed to the computer that is connecting to the IPSec
server. Refer to “Problem #9, I need to set up online game hosting or use other Internet applications” for
details. Check the Linksys website at www.linksys.com for more information.
8. I need to set up a server behind my Router.
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.
A. Access the Router’s Web-based Utility by going to http://192.168.15.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Range Forwarding tab.
B. Enter any name you want to use for the Application.
60
Appendix A: Troubleshooting
Common Problems and Solutions
Wireless-G Broadband Router with 2 Phone Ports
C. Enter the port range of the service you are using. For example, if you have a web server, you would enter
the range 80 to 80.
D. Select the protocol you will be using, TCP or UDP, or select Both.
E. 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 192.168.15.100, you would enter 100 in the field
provided. Check “Appendix C: Finding the MAC Address and IP Address for Your Ethernet Adapter” for
details on getting an IP address.

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:

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:
A. Access the Router’s Web-based Utility by going to http://192.168.15.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Range Forwarding tab.
B. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to
use it at a later time.
C. Click the DMZ tab.
D. Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet. This will
bypass the NAT security for that computer. Please refer to “Appendix C: Finding the MAC Address and IP
Address for Your Ethernet Adapter” for details on getting an IP address.
Once completed with the configuration, click the Save Settings button.
11. I forgot my password, or the password prompt always appears when saving settings to the Router.
Reset the Router to factory defaults by pressing the Reset button for five seconds and then releasing it. If
you are still getting prompted for a password when saving settings, then perform the following steps:
A. Access the Router’s web interface by going to http://192.168.15.1 or the IP address of the Router.
Enter the default password admin, and click the Administration => Management tab.
B. Enter a different password in the Router Password field, and enter the same password in the second
field to confirm the password.
C. Click the Save Settings button.

12. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.
If you have proxy settings, you need to disable these on your computer. Because the Router is the gateway
for the Internet connection, the computer does not need any proxy settings to gain access. Please follow
these directions to verify that you do not have any proxy settings and that the browser you use is set to
connect directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
A.
B.
C.
D.
E.
Click Start, Settings, and Control Panel. Double-click Internet Options.
Click the Connections tab.
Click the LAN settings button and remove anything that is checked.
Click the OK button to go back to the previous screen.
Click the option Never dial a connection. This will remove any dial-up pop-ups for PPPoE users.
For Netscape 4.7 or higher:
A. Start Netscape Navigator, and click Edit, Preferences, Advanced, and Proxies.
B. Make sure you have Direct connection to the Internet selected on this screen.
C. Close all the windows to finish.
13. To start over, I need to set the Router to its router factory defaults.
Hold the Reset button for approximately five seconds and then release it. This will return the password,
forwarding, and other settings on the Router to the factory default settings. In other words, the Router will
revert to its original factory configuration.
14. My DSL service’s PPPoE is always disconnecting.
PPPoE is not actually a dedicated or always-on connection. The DSL ISP can disconnect the service after a
period of inactivity, just like a phone dial-up connection to the Internet. There is a setup option to “keep
alive” the connection. This may not always work, so you may need to re-establish connection periodically.

for more information on which incoming port services are required by the Internet application.
17. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
Go through this checklist until your problem is solved:
• Check if other PCs work. If they do, ensure that your workstation’s IP settings are correct (IP Address,
Subnet Mask, Default Gateway, and DNS). Restart the computer that is having a problem.
• If the PCs are configured correctly, but still not working, check the Router. Ensure that it is connected and
powered on. Connect to it and check its settings. (If you cannot connect to it, check the LAN and power
connections.)
• If the Router is configured correctly, check your Internet connection (DSL/cable modem, etc.) to see if it
is working correctly. You can remove the Router to verify a direct connection.
• Manually configure the TCP/IP with a DNS address provided by your ISP.
• Make sure that your browser is set to connect directly and that any dial-up is disabled. For Internet
Explorer, click Tools, Internet Options, and then the Connection tab. Make sure that Internet Explorer
is set to Never dial a connection. For Netscape Navigator, click Edit, Preferences, Advanced, and
Proxy. Make sure that Netscape Navigator is set to Direct connection to the Internet.

Appendix A: Troubleshooting
Frequently Asked Questions
67
Wireless-G Broadband Router with 2 Phone Ports
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 the LAN.
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 98, Millennium, 2000, or 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.
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 to 27900. If you want to use the UT Server Admin, forward another port
(8080 usually works well but is used for remote admin. You may have to disable this.), and 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.

You may have to remove the proxy settings on your Internet browser, e.g., Netscape Navigator or Internet
Explorer. Or remove the dial-up settings on your browser. Check with your browser documentation, and make
sure that your browser is set to connect directly and that any dial-up is disabled. Make sure that your browser is
set to connect directly and that any dial-up is disabled. For Internet Explorer, click Tools, Internet Options, and
then the Connection tab. Make sure that Internet Explorer is set to Never dial a connection. For Netscape
Navigator, click Edit, Preferences, Advanced, and Proxy. Make sure that Netscape Navigator is set to Direct
connection to the Internet.
What is DMZ Hosting?
Demilitarized Zone (DMZ) allows one IP address (computer) to be exposed to the Internet. Some applications
require multiple TCP/IP ports to be open. It is recommended that you set your computer with a static IP if you
want to use DMZ Hosting. To get the LAN IP address, see “Appendix C: Finding the MAC Address and IP Address
for Your Ethernet Adapter.”
If DMZ Hosting is used, does the exposed user share the public IP with the Router?
No.

Frequently Asked Questions
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 to communicate continuously while moving freely throughout an
area greater than that covered by a single access point. Before using the roaming function, the user must make
sure that the computer uses the same channel number that is used by the access point of the 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
Appendix A: Troubleshooting
Frequently Asked Questions
73
Wireless-G Broadband Router with 2 Phone Ports
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
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
Spread-Spectrum (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.

Linksys wants to make wireless networking as safe and easy for you as possible. The current generation of
Linksys products provide several network security features, but they require specific action on your part for
implementation. So, keep the following in mind whenever you are setting up or using your wireless network.
Security Precautions
The following is a complete list of security precautions to take (at least steps 1 through 5 should be followed):
1. Change the default SSID.
2. Disable SSID Broadcast.
3. Change the default password for the Administrator account.
4. Enable MAC Address Filtering.
5. Change the SSID periodically.
NOTE: Some of these security
features are available only
through the network router or
access point. Refer to the
router or access point’s
documentation for more
information.
6. Use the highest encryption algorithm possible. Use WPA if it is available. Please note that this may reduce
your network performance.
7. Change the WEP encryption keys periodically.
For information on implementing these security features, refer to “Chapter 6: Configuring the 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.
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.
78
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
Wireless-G Broadband Router with 2 Phone Ports
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.
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.
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
79
Wireless-G Broadband Router with 2 Phone Ports
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.
