Welcome
Wireless-G Travel Router with SpeedBooster
Chapter 1: Introduction
Welcome
Thank you for choosing the Linksys Wireless-G Travel Router with SpeedBooster. The Wireless-G Travel Router
with SpeedBooster will allow you to network wirelessly better than ever, sharing Internet access, files and fun,
easily and securely while away from home.
How does the Wireless-G Travel Router with SpeedBooster do all of this? The Router has a built-in access point,
which lets you connect SpeedBooster-enhanced and regular Wireless-G and Wireless-B devices to the network.
There's also an Ethernet port to connect your wired PC. The Router function ties it together and lets your PCs
share a wired or wireless Internet connection. The travel-friendly form factor includes a built-in power supply and
antenna, and it comes with a travel case. Just plug the Router directly into the wall, and connect the hotel's fast
Internet service cable. Then use the Router's push button setup feature to easily connect and configure your
wireless devices. You just push the button on the Router and on your other SecureEasySetup-enabled wireless
device to automatically create a WPA or WEP encryption-secured wireless connection. You can also use multiple
devices on a single hotspot account in a coffee shop or airport lounge and be protected with WPA Personal
encryption or a powerful SPI firewall. The Router also supports VPN pass-through and it can serve as a DHCP
Server.
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 Travel Router with SpeedBooster bridges wireless
networks of 802.11a, 802.11b, and 802.11g standards and wired networks, allowing them to communicate with
each other.
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 Travel Router with SpeedBooster, set it up, and configure it to bridge your network. These instructions
should be all you need to get the most out of the Wireless-G Travel Router with SpeedBooster.
ethernet: an IEEE standard network protocol that
specifies how data is placed on and retrieved from
a common transmission medium.
lan (local area network): the computers and
networking products that make up the network
in your home or office.
802.11b: an IEEE wireless networking standard
that specifies a maximum data transfer rate of
11Mbps and an operating frequency of 2.4GHz.
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.
browser: an application program that
provides a way to look at and interact with all
the information on the World Wide Web.
mbps: one million bits per second; a unit of
measurement for data transmission.
nat (network address translation): NAT
technology translated IP addresses of a
local area network to a different IP address
for the Internet.

Chapter 2: Planning Your Wireless Network
Network Topology
Wireless-G Travel Router with SpeedBooster
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 Travel Router with SpeedBooster, which serves as the main point of communications in a wireless
network. The Router transmits data to PCs equipped with wireless network adapters, which can roam within a
certain radial range of the Router. You can arrange the Router and multiple access points to work in succession
to extend the roaming range, and you can set up your wireless network to communicate with your Ethernet
hardware as well.
If the wireless network is relatively small and needs to share resources only with the other computers on the
wireless network, then the Ad-Hoc mode can be used. Ad-Hoc mode allows computers equipped with wireless
transmitters and receivers to communicate directly with each other, eliminating the need for a wireless router or
access point. The drawback of this mode is that in Ad-Hoc mode, wireless-equipped computers are not able to
communicate with computers on a wired network. And, of course, communication between the wireless-
equipped computers is limited by the distance and interference directly between them.
Network Layout
The Wireless-G Travel Router with SpeedBooster has been specifically designed for use with 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: your wireless network’s name.
ad-hoc: a group of wireless devices
communicating directly to each other
(peer-to-peer) without the use of an
access point.
access point: a device that allows wireless-
equipped computers and other devices to
communicate with a wired network. Also used
to expand the range of a wireless network.
adapter: a device that adds
network functionality to your PC.
ethernet: IEEE standard network protocol that
specifies how data is placed on and retrieved
from a common transmission medium.
network: a series of computers or devices
connected for the purpose of data sharing,
storage, and/or transmission between users.

The Setup Tab - Advanced Routing
This tab is used to set up the Router’s advanced functions. Operating Mode allows you to select the type(s) of
advanced functions you use. Dynamic Routing will automatically adjust how packets travel on your network. Static
Routing sets up a fixed route to another network destination.
NAT (Network Address Translation). NAT technology translates IP addresses of a local area network to a
different IP address for the Internet. To enable NAT, click Enabled. To disable NAT, click Disabled.
Dynamic Routing (RIP)
. This feature enables the Router to automatically adjust to physical changes in the
network’s layout and exchange routing tables with the other router(s). The Router determines the network packets’
route based on the fewest number of hops between the source and the destination. This feature is
Disabled
by
default.
Static Routing
. A static route is a pre-determined pathway that network information must travel to reach a specific
host or network. To set up a static route between the Router and another network, enter the information described
below to set up a new static route by clicking the
Add New Entry
button to add an entry. Click the
Update Selected
Entry
button to change an existing entry. (Click the
Delete
button to delete a static route.)
Destination LAN IP
. The Destination LAN IP is the address of the remote network or host to which you want to
assign a static route.
Enter the IP address of the host for which you wish to create a static route. If you are
building a route to an entire network, be sure that the network portion of the IP address is set to 0. For
example, the Router’s standard IP address is 192.168.16.1. Based on this address, the address of the routed
network is 192.168.16, with the last digit determining the Router’s place on the network. Therefore you would
enter the IP address 192.168.16.0 if you wanted to route to the Router’s entire network, rather than just to the
Router.
Subnet Mask
. The Subnet Mask determines which portion of a Destination LAN IP address is the network
portion, and which portion is the host portion.
For example, a network may have the Subnet Mask of
255.255.255.0. This determines (by using the values 255) that the first three numbers of a network IP address
identify this particular network, while the last digit (from 1 to 254) identifies the specific host.
Default Gateway
. This is the IP address of the gateway device that allows for contact between the Router and
the remote network or host.
Interface
. This interface tells you whether the Destination IP Address is on the
LAN & Wireless
(Ethernet and
wireless networks) or the
Internet
(WAN). From the drop-down menu, you can also select
LAN & Wireless
, which
performs dynamic routing over your Ethernet and wireless networks. You can also select
WAN
, which performs
dynamic routing with data coming from the Internet. Finally, selecting
Both
enables dynamic routing for both
networks, as well as data from the Internet.

Wireless Security
WEP. WEP is a basic encryption method. Select a level of WEP encryption, 40/64-bit Hex digits or 128-bit Hex
digits. If you want to use a Passphrase, then enter it in the Passphrase field and click the Generate button. If you
want to enter the WEP key manually, then enter it in the WEP Key 1-4 field(s). To indicate which WEP key to use,
select the appropriate TX Key number.
• Passphrase. Instead of manually entering WEP keys, you can enter a passphrase. It is used to generate one or
more WEP keys. It is case-sensitive and should not be longer than 32 alphanumeric characters. (This
Passphrase function is compatible with Linksys wireless products only. If you want to communicate with non-
Linksys wireless products, make a note of the WEP key generated in the Key 1 field, and enter it manually in
the wireless client.) After you enter the Passphrase, click the Generate button to create WEP keys.
• TX Key Select which WEP key (1-4) will be used when the Router sends data. Make sure that the receiving
device (wireless client) is using the same key.
• WEP Keys 1-4. WEP keys enable you to create an encryption scheme for wireless network transmissions. If
you are not using a Passphrase, then manually enter a set of values. (Do not leave a key field blank, and do
not enter all zeroes; they are not valid key values.) If you are using 64-bit WEP encryption, the key must be
exactly 10 hexadecimal characters in length. If you are using 128-bit WEP encryption, the key must be exactly
26 hexadecimal characters in length. Valid hexadecimal characters are “0”-“9” and “A”-“F”.
WPA-Personal. This method offers two encryption methods, TKIP and AES, with dynamic encryption keys. Select
the type of encryption method you want to use, TKIP or AES. Enter the Passphrase, which can have 8 to 63
characters. Then enter the Key Renewal period, which instructs the Router how often it should change the
encryption keys.

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.
Advanced Wireless
Frame Burst Mode. Enabling this option should provide your network with greater performance, depending on
the manufacturer of your wireless products. If you are not sure how to use this option, keep the default, Enabled
(Default).
AP Isolation. This isolates all wireless clients and wireless devices on your network from each other. Wireless
devices will be able to communicate with the Router but not with each other. To use this function, click Enabled.
AP Isolation is disabled by default.
Authentication Type. The default is set to Open System, 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.
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.
Transmission 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 (Default) 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
(Default).
CTS Protection Mode. CTS (Clear-To-Send) Protection Mode should be set to Auto (Default). The Router will
automatically use CTS Protection Mode when your Wireless-G products are experiencing severe problems and
are not able to transmit to the Router in an environment with heavy 802.11b traffic. This function boosts the
Router’s ability to catch all Wireless-G transmissions but will severely decrease performance.
Beacon Interval. The default value is 100. 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.

DTIM Interval. This value 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.
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.
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 Remote Security Gateway is the VPN device, such as a second VPN Router, on the remote end of the VPN
tunnel. Under Remote Security Gateway, you have three options: IP Address, FQDN, and Any. In this section, you
can also set the levels and types of encryption and authentication.
IP Address. If you select IP Address, enter the IP Address of the VPN device at the other end of the tunnel.
The remote VPN device can be another VPN Router, a VPN Server, or a computer with VPN client software that
supports IPSec. The IP Address may either be static (permanent) or dynamic (changing), depending on the
settings of the remote VPN device. Make sure that you have entered the IP Address correctly, or the
connection cannot be made. Remember, this is NOT the IP Address of the local VPN Router, but the IP Address
of the remote VPN Router or device with which you wish to communicate.
FQDN (Fully Qualified Domain Name). If you select FQDN, enter the FQDN of the VPN device at the other end of
the tunnel. The remote VPN device can be another VPN Router, a VPN Server, or a computer with VPN client
software that supports IPSec. The FQDN is the host name and domain name for a specific computer on the
Internet, for example, vpn.myvpnserver.com.

Any. If you select Any for the Remote Security Gateway, the VPN device at the other end of the tunnel will
accept a request from any IP address. The remote VPN device can be another VPN Router, a VPN Server, or a
computer with VPN client software that supports IPSec. If the remote user has an unknown or dynamic IP
address (such as a professional on the road or a telecommuter using DHCP or PPPoE), then Any should be
selected.
Encryption. Using Encryption also helps make your connection more secure. There are two different types of
encryption: DES or 3DES (3DES is recommended because it is more secure). You may choose either of these,
but it must be the same type of encryption that is being used by the VPN device at the other end of the tunnel.
Or, you may choose not to encrypt by selecting Disable.
Authentication. Authentication acts as another level of security. There are two types of authentication: MD5
and SHA (SHA is recommended because it is more secure). As with encryption, either of these may be
selected, provided that the VPN device at the other end of the tunnel is using the same type of authentication.
Or, both ends of the tunnel may choose to Disable authentication.
Key Management
In order for any encryption to occur, the two ends of the tunnel must agree on the type of encryption and the way
the data will be decrypted. This is done by sharing a “key” to the encryption code. Under Key Management, you
may choose automatic or manual key management.
Automatic Key Management. Select Auto (IKE) and enter a series of numbers or letters in the Pre-shared
Key field. Check the box next to PFS (Perfect Forward Secrecy) to ensure that the initial key exchange and IKE
proposals are secure. In the example shown the word chappy is used. Based on this word, which MUST be
entered at both ends of the tunnel if this method is used, a key is generated to scramble (encrypt) the data
being transmitted over the tunnel, where it is unscrambled (decrypted). You may use any combination of up
to 24 numbers or letters in this field. No special characters or spaces are allowed. In the Key Lifetime field,
you may optionally select to have the key expire at the end of a time period of your choosing. Enter the
number of seconds you’d like the key to be useful, or leave it blank for the key to last indefinitely.
Manual Key Management. Similarly, you may choose Manual keying, which allows you to generate the key
yourself. Enter your key into the Encryption KEY field. Then enter an Authentication KEY into that field. These
fields must both match the information that is being entered in the fields at the other end of the tunnel. Up to
24 alphanumeric characters are allowed to create the Encryption Key. Up to 20 alphanumeric characters are
allowed to create the Authentication Key.
The Inbound SPI and Outbound SPI fields are different, however. The Inbound SPI value set here must match
the Outbound SPI value at the other end of the tunnel. The Outbound SPI here must match the Inbound SPI
value at the other end of the tunnel. That is, the Inbound SPI and Outbound SPI values would be opposite on
the other end of the tunnel. Only numbers can be used in these fields. After you click the Save Settings
30
Chapter 5: Configuring the Wireless-G Travel Router with SpeedBooster
The Security Tab - VPN
Wireless-G Travel Router with SpeedBooster
button, hexadecimal characters (series of letters and numbers) are displayed in the Inbound SPI and
Outbound SPI fields.
The Status field at the bottom of the screen will show when a tunnel is active.
To connect a VPN tunnel, click the Connect button. The View Logs button, when logging is enabled on the Log
screen of the Administration tab, will show you VPN activity on a separate screen. The VPN Log screen displays
successful connections, transmissions and receptions, and the types of encryption used. For more advanced VPN
options, click the Advanced Setting button to open the Advanced Setting screen.
When finished making your changes on this screen, click the Save Settings button to save these changes, or
click the Cancel Changes button to undo your changes.
Advanced VPN Tunnel Setup
From the Advanced Settings screen you can adjust the settings for specific VPN tunnels.
Phase 1
. Phase 1 is used to create a security association (SA), often called the IKE SA. After Phase 1 is completed, Phase
2 is used to create one or more IPSec SAs, which are then used to key IPSec sessions.
Operation Mode
. There are two modes: Main and Aggressive, and they exchange the same IKE payloads in different
sequences. Main mode is more common; however, some people prefer Aggressive mode because it is faster. Main mode
is for normal usage and includes more authentication requirements than Aggressive mode. Main mode is recommended
because it is more secure. No matter which mode is selected, the VPN Router will accept both Main and Aggressive
requests from the remote VPN device. If a user on one side of the tunnel is using a Unique Firewall Identifier, this should
be entered under the
Username
field.
Encryption
. Select the length of the key used to encrypt/decrypt ESP packets. There are two choices: DES and 3DES.
3DES is recommended because it is more secure.
Authentication
. Select the method used to authenticate ESP packets. There are two choices: MD5 and SHA. SHA is
recommended because it is more secure.
Group
. There are two Diffie-Hellman Groups to choose from: 768-bit and 1024-bit. Diffie-Hellman refers to a
cryptographic technique that uses public and private keys for encryption and decryption.
Key Lifetime
. In the Key Lifetime field, you may optionally select to have the key expire at the end of a time period of your
choosing. Enter the number of seconds you’d like the key to be used until a re-key negotiation between each endpoint is
completed.
Phase 2
Group
. There are two Diffie-Hellman Groups to choose from: 768-bit and 1024-bit. Diffie-Hellman refers to a
cryptographic technique that uses public and private keys for encryption and decryption.

The Applications and Gaming Tab - Port Range Forwarding
The Port Range Forwarding screen allows you to set 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.)
Before using forwarding, you should assign static IP addresses to the designated PCs.
Port Range Forwarding
To forward a port, enter the information on each line for the criteria required. Descriptions of each criteria are
described here.
Application Name. Each drop-down menu offers a choice of ten preset applications (select None if you do not
want to use any of the preset applications). Select up to five preset applications. 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:
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.
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.
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.
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.
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.
tcp: a network protocol for transmitting data
that requires acknowledgement from the
recipient of data sent.
udp: a network protocol for transmitting data
that does not require acknowledgement from
the recipient of the data that is sent.

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.).
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.
TFTP (Trivial File Transfer Protocol). A version of the TCP/IP FTP protocol that has no directory or password
capability.
Web. The Internet.
Start/End Port. This is the port range. Enter the port number or range of external ports used by the server or
Internet application. Check with the software documentation of the Internet application for more information.
Protocol. Select the protocol(s) used for this application, TCP and/or UDP.
To IP Address. For each application, enter the IP address of the PC running the specific application.
Enabled. Click the Enabled checkbox to enable port forwarding for the relevant application.

The DMZ feature allows one network user to be exposed to the Internet for use of a special-purpose service such
as Internet gaming or videoconferencing. DMZ hosting forwards all the ports at the same time to one PC. The Port
Range Forwarding feature 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.

6. 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://192.168.16.1 or the IP address of the Router.
Go to the Applications & Gaming => Port Range Forwarding tab.
2. Enter any name you want to use for the custom 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 192.168.16.100, 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.
6. Check the Enabled option for the port services you want to use. Consider the example below:
When you have completed the configuration, click the Save Settings button.

7. 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://192.168.16.1 or the IP address of the Router. Go
to the Applications & Gaming => Port Range Forwarding tab.
2. Enter any name you want to use for the custom 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,
if the web server’s Ethernet adapter IP address is 192.168.16.100, 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.
6. Check the Enabled option for the port services you want to use. Consider the example below:
When you have completed the configuration, click the Save Settings button.
8. 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.)
Application Start ~ End Port Protocol IP Address Enabled

1300
16. The Power LED keeps flashing.
The Power LED flashes when the device is first powered up. Meantime, the system will boot up itself and
check for proper operation. After finishing the checking procedure, the LED stays solid to show that the
system is working fine. If the LED keeps flashing after this time, the device is not working properly. Try to
flash the firmware by assigning a static IP address to the computer, and then upgrade the firmware. Try using
the following settings, IP Address: 192.168.16.50 and Subnet Mask: 255.255.255.0.
17. When I enter a URL or IP address, I get a time-out error or am prompted to retry.
• 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 settings 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

Frequently Asked Questions
Wireless-G Travel Router with SpeedBooster
Frequently Asked Questions
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.
54
Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G Travel Router with SpeedBooster
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?
Reset the Router by holding down the reset button until the Power LED fully turns on and off. Reset your cable or
DSL modem by powering the unit off and then on. Obtain and flash the latest firmware release that is readily
available on the Linksys website, www.linksys.com.
How will I be notified of new Router firmware upgrades?
All Linksys firmware upgrades are posted on the Linksys website at www.linksys.com, where they can be
downloaded for free. To upgrade the Router’s firmware, use the Administration tab of the Router’s web-based
utility. If the Router’s Internet connection is working well, there is no need to download a newer firmware version,

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 E: 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.
Does the Router pass PPTP packets or actively route PPTP sessions?
The Router allows PPTP packets to pass through.
Is the Router cross-platform compatible?
Any platform that supports Ethernet and TCP/IP is compatible with the Router.
How many ports can be simultaneously forwarded?

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 workstation uses the same channel number as 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
58
Appendix A: Troubleshooting
Frequently Asked Questions
Wireless-G Travel Router with SpeedBooster
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
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 64-bit or 128-bit shared key algorithm, as
described in the IEEE 802.11 standard.
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?
Turn the stand on the bottom panel, press the Reset button, and hold in for about eight 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.
You may also attach an optional external SMA antenna for longer range.

Appendix B: Wireless Security
Security Precautions
Wireless-G Travel Router with SpeedBooster
Appendix B: Wireless Security
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.
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 5: Configuring the Wireless-G Travel
Router with SpeedBooster.”
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.
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.
61
Appendix B: Wireless Security
Security Threats Facing Wireless Networks
Wireless-G Travel Router with SpeedBooster
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
WPA. Wi-Fi Protected Access (WPA) is the newest and best available standard in Wi-Fi security. WPA2 is the
newer version of Wi-Fi Protected Access with stronger encryption than WPA. WPA gives you a choice of two
encryption methods: TKIP (Temporal Key Integrity Protocol), which utilizes a stronger encryption method and
incorporates Message Integrity Code (MIC) to provide protection against hackers, and AES (Advanced Encryption
System), which utilizes a symmetric 128-Bit block data encryption.
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.
62
Appendix B: Wireless Security

WPA-Personal. Select the type of algorithm, TKIP or AES, enter a password in the Passphrase 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.
WPA2-Personal. WPA2 gives you one encryption method, AES, with dynamic encryption keys. Enter a
Passphrase of 8-63 characters. Then enter a Group Key Renewal period, which instructs the Router how often
it should change the encryption keys.
WPA2-Mixed Mode. WPA2 Mixed Mode gives you TKIP+AES encryption. Enter a Passphrase of 8-63
characters. Then enter a Group Key Renewal period, which instructs the Router 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.
