Chapter 1: Introduction
The Wireless Cable/DSL Router
Think of the Network Everywhere Wireless Cable/DSL Router as a kind of
"splitter" for your Internet connection. Just connect your DSL or Cable
Modem to the Router, and all the computers in your household can share the
Internet -- all at the same time. You can connect your home computers to the
Router with Ethernet cables, or put wireless network adapters in them and communicate over radio waves, saving the trouble and expense of running cables
through your house.
Once your computers are connected to the Router, they can communicate with
each other too, sharing resources and files. All your computers can print on a
shared printer connected anywhere in the house. And your computers can share
all kinds of files -- music, digital pictures, and documents. Keep all your digital music on one computer, and listen to it anywhere in the house. Organize
all of your family's digital pictures in one place, to simplify finding the ones
you want, and easing backup to CD-R. Utilize extra free space on one computer when another's hard drive starts to fill up.
Your home network is secure, too. All wireless communications are protected
by 128-bit encryption. Internet Firewall packet filters keep intruders out, and
block attacks. Parental Controls help you protect your family.It's all easier than
you think -- the included Setup Wizard takes you through configuring your network, step by step. With the Network Everywhere Wireless Cable/DSL Router
at the heart of your home network, you don't need to be a networking genius to
share printers, files, and your Internet connection -- with or without wires.

Wireless Cable/DSL Router
An Introduction to LANs and WANs
Simply put, a router is a network device that connects two networks together.
In this instance, the Router connects your Local Area Network (LAN), or the
group of PCs in your home or office, to the Wide Area Network (WAN) that is
the Internet. The Router processes and regulates the data that travels between
these two networks.
Think of the Router as a network device with two sides. The first side is made
up of your private Local Area Network (LAN) of PCs. The other, public side
is the Internet, or the Wide Area Network (WAN), outside of your home or
office.
The Router’s firewall (NAT) protects your network of PCs so users on the public, Internet side cannot “see” your PCs. This is how your LAN, or network,
remains private. The Router protects your network by inspecting the first packet coming in from the Internet port before delivery to the final destination on
the LAN port. The Router inspects Internet port services like the web server,
ftp server, or other Internet applications, and, if allowed, it will forward the
packet to the appropriate PC on the LAN side.
IP Addresses
What’s an IP Address?
IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its “location,” or address, on the network. This applies to both the Internet and LAN
connections.
There are two ways of assigning an IP address to your network devices.
Static IP Addresses
A static IP address is a fixed IP address that you assign manually to a PC or
other device on the network. Since a static IP address remains valid until you
disable it, static IP addressing insures that the device assigned it will have that
same IP address until you change it. Static IP addresses are commonly used
with network devices such as server PCs or print servers.
If you use the Router to share your cable or DSL Internet connection, contact
your ISP to find out if they have assigned a static IP address to your account.
If so, you will need that static IP address when configuring the Router. You can
get the information from your ISP.
Network Everywhere® Series
Note: Since the Router is a device that connects two networks, it needs two
IP addresses—one for the LAN side, and one for the Internet side. In this
User Guide, you’ll see references to the “Internet IP address” and the “LAN
IP address.”
Wireless Cable/DSL Router
The Router’s Ports
Since the Router has firewall security (NAT), only the Router’s Internet IP
address can be seen from the Internet.
However, even the Internet IP address can be blocked, so that the Router and
network seem invisible to the Internet—This is shown in the Filters section in
“Chapter 6: The Routers Web-Based Utility”.
Dynamic IP Addresses
A dynamic IP address is automatically assigned to a device on the network,
such as PCs and print servers. These IP addresses are called “dynamic”
because they are only temporarily assigned to the PC or device. After a certain
time period, they expire and may change. If a PC logs on to the network (or the
Internet) and its dynamic IP address has expired, the DHCP server will assign
it a new dynamic IP address.
For DSL users, many ISPs may require you to log on with a user name and
password to gain access to the Internet. This is called “Point to Point Protocol
over Ethernet” or PPPoE. PPPoE is similar to a dial-up connection but does not
have a phone number to dial into, and PPPoE is a dedicated high-speed connection. PPPoE also will provide the Router with a dynamic IP address to
establish a connection to the Internet.
DHCP (Dynamic Host Configuration Protocol) Servers
The
Figure 1-1
Router’s rear panel (as shown in Figure 1-1) is where all of its connections are
made.
Internet
The Internet Port is where you will connect your cable or
DSL modem with an Ethernet cable. Your modem connection will not work from any other port.
Ports 4, 3, 2
These four LAN (Local Area Network) ports are where
you will connect networked devices, such as PCs, print
servers, and any other Ethernet devices you want to put
on your network. If Port 1 is being used, the Uplink Port
will not work.
DHCP frees you from having to assign IP addresses manually every time a new
user is added to your network. PCs and other network devices using dynamic
IP addressing are assigned a new IP address by a DHCP server. The PC or network device obtaining an IP address is called the DHCP client. The Router’s
Internet port is, by default, set as a DHCP client.
DHCP servers can either be a designated PC on the network or another network
device, such as the Router. By default, a DHCP server is enabled on your
Router’s LAN ports. If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you run more than one
DHCP server on your network, you will experience network errors, such as
conflicting IP addresses. To disable the Router’s DHCP function, see the
DHCP section in Chapter 6: The Router’s Web-Based Utility.
Note: Even if you assign a static IP address to a PC, other PCs can still use
DHCP’s dynamic IP addressing, as long as the static IP is not within the
DHCP range of the LAN IP Address.
Port 1/Uplink Port The Uplink Port is where you can expand your network
by connecting to a switch. Uplinking to a switch is done
by simply running a cable from the Uplink Port to the
other device. The Uplink Port is shared with Port 1.
Pushing in the Uplink button allows this port to be used
as the Uplink port. If the Uplink button is not pushed in,
this port functions the same as Ports 4, 3, and 2.
Power
The Power Port is where you will connect the included
AC Power adapter.
If the Router’s DHCP function fails to provide a dynamic IP address for any
reason, please refer to Appendix A: Troubleshooting.

Green. This LED also serves two purposes. When this LED
is lit continuously, the connection made through the corresponding port is running in Full Duplex mode. A blinking
LED indicates that the connection is experiencing collisions.
Infrequent collisions are normal. If this LED blinks too
often, there may be a problem with your connection. Refer to
the Troubleshooting Appendix if you think there is a problem.
100
Orange. This LED indicates when a successful 100Mbps
connection is made through the corresponding port.
Pressing the Reset Button and holding it in for a few seconds will clear all
of the Router’s data and restore the factory defaults. This should be done
only if you are experiencing heavy routing problems, and only after you
have exhausted all of the other troubleshooting options. By resetting the
Router, you run the risk of creating conflicts between your PCs’ actual IP
Addresses and what the Router thinks their IP Addresses should be. You
may be forced to reboot each network PC.
If the Router locks up, simply press the reset button or power it down for
three to five seconds by removing the power cable from the Router’s
Power Port. Leaving the power off for too long could result in the loss of
network connections.

Chapter 2: Planning Your Wireless
Network
Network Topology
A wireless LAN is exactly like a regular LAN, except that each computer in the
LAN uses a wireless adapter to connect to the network through a wireless connection. Computers in a wireless LAN must be configured to share the same
radio channel.
The wireless adapter provides LAN access for wireless workstations. An integrated wireless and wired LAN is called an Infrastructure configuration. A
group of wireless adapter users and this Router compose a Basic Service Set
(BSS). Each PC equipped with a wireless adapter in a BSS can talk to any
computer in a wired LAN infrastructure via this Router.
An infrastructure configuration extends the accessibility of a PC with a wireless adapter to a wired LAN, and doubles the effective wireless transmission
range for two PCs equipped with a wireless adapter Since this Router is able
to forward data within its BSS, the effective transmission range in an infrastructure LAN is doubled.

Chapter 3: Connecting the Router
Before plugging everything together, it’s always a good idea to have everything
you’ll need
to get
the Router up and running. Depending upon how you conBefore
You
Start
figure the Router in Chapter 6: The Router’s Web-based Utility, you may need
some of the following values from your ISP:
When connecting through a Static IP connection, be sure to have 1) Your
broadband-configured PC’s fixed Internet IP Address, 2) Your broadbandconfigured PC’s Computer Name and Workgroup Name, 3) Your Subnet
Mask, 4) Your Default Gateway, and 5) Your Primary DNS IP address.
When connecting through a PPPoE connection, be sure to have 1) Your
PPPoE User Name and 2) Your PPPoE Password.
The installation technician from your ISP should have left this information with
you after installing your broadband connection. If not, you can call your ISP to
request the data.
Once you have the above values, you can begin the Router’s installation and
setup.
Roaming
Infrastructure mode also supports roaming capabilities for mobile users. More
than one BSS can be configured as an Extended Service Set (ESS). This continuous network allows users to roam freely within an ESS. All PCs that are
equipped with a wireless adapter, and are within one ESS, must be configured
with the same ESS ID.
Before enabling an ESS with roaming capability, it is recommended to select a
feasible radio channel and optimum Router position. Proper positioning combined with a clear radio signal will greatly enhance performance.
Once you are sure that you have the above values on hand, you can begin the
Installation and Your
Setup of
the Router. Together and Booting Up
Connecting
Hardware
1. Power everything down, including your PCs, your cable or DSL modem and
the Router.
2. Connect an Ethernet cable from one of your PC’s Ethernet ports to one of the
Router’s LAN ports. Do the same with all the PCs you wish to connect to the
Router.
In addition to accessing the Router through an Ethernet connection, a wireless connection can be used to access the Router. See the “For Wireless
Connections” note that follows these connection instructions.
3. Connect another Ethernet cable from your cable or DSL modem to the
Router’s Internet port.
4. Connect the Power Adapter (included) to the Router’s Power port and plug
the other end into a power outlet.
Network Everywhere® Series
• The Power LED will illuminate green as soon as the power adapter is connected.
• The Diag LED will illuminate red for a few seconds while the Router
goes through its internal diagnostic test. The LED will turn off when the
self-test is complete.
5. Power on the cable or DSL modem. Verify that the power is on by checking
the Link LED in the Internet column on the front of the Router. The Link
LED will be illuminated if the power is on and the modem is ready.
6. Press the Reset button on the back of the Router. Hold the button in for three
seconds, or until the Diag LED illuminates red. This restores the Router’s
default settings.
7. Power on your PC.
The Router is now connected.
Continue to the next chapter to configure your PCs.
For Wireless Connections: In addition to accessing the Router through an
Ethernet connection, a wireless connection can be used to access the Router.
After powering on the Router and connecting it to your modem, enter the
Router’s IP Address in the Address field of your wireless PC’s web-browser as
follows: http://192.168.1.1 and press Enter.
Important: The Router is configured by default to work out of the box
with all Network Everywhere Wireless Adapters. If you have
changed the defaults on your Network Everywhere Wireless
Adapters, or are using other wireless adapters, you must temporarily change your wireless adapter settings to: (SSID = wireless) in
order to initially access the Router wirelessly. After you have
accessed the Router with the default settings, you can change the
Router’s settings to coincide with your Network settings and reset
your adapters.
Important: Some ISPs—most notably some cable providers—configure their networks so that you do not have to enter a full Internet
address into your web browser or e-mail application to reach your
home page or receive your e-mail. If your Internet home page
address is something very simple, such as “www”, rather than
“www.networkeverywhere.com”, or your e-mail server’s address is
something similar to “e-mail” or “pop3”, rather than “pop.mail.networkeverywhere.com”, you won’t be able to properly configure the
Router until you determine the actual Internet addresses of your
Web and e-mail connections.

Chapter 4: Configuring the PCs
Overview
These instructions will help you configure each of your computers to communicate with the Router.
To do this, you will need to configure your PC’s network settings to obtain an
IP (or TCP/IP) address automatically. Computers use IP addresses to communicate with each other across a network or the Internet.
You will need to know which operating system your computer is running, such
as Windows 98 SE, Millennium, 2000, or XP. You can find out by clicking the
Start button and then selecting the Settings option. (If your Start menu doesn’t have a Settings option, you’re running Windows XP. You can select the
Control Panel directly from the Start Menu.) Then, click Control Panel and
double-click the System icon. Click the Cancel button when done.
Once you know which Windows operating system you are running, follow the
directions in this step for your computer’s operating system. If you PC is not
configured with the TCP/IP protocol, you will need to do this for each computer you are connecting to the Router.
The next few pages tell you, step by step, how to configure your TCP/IP settings based on the type of Windows operating system you are using. Once
you've configured your computers, continue to Chapter 6: The Router’s Webbased Utility.
Configuring Windows 98 SE and Millennium PCs
1. Click the Start button, click Settings and open the Control Panel. From
there, double-click the Network icon to open the Network screen.

The Preset Applications at the top of the list 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, web developers typically
upload the files to the web server using FTP. FTP includes functions to log
onto the network, list directories, and copy files. FTP operations can be performed by typing commands at a command prompt or via an FTP utility
running under a graphical interface such as Windows. FTP transfers can
also be initiated from within a web browser by entering the URL preceded
by 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.
•
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 his or her 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, for example, name@universityname.edu.
•
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. (SMTP may also need to be forwarded.)

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, the Router’s DHCP
function must be disabled under the DHCP tab and the Router must be assigned
a new static LAN IP address because the IP address may change when using
the DHCP server.
If you need to forward all ports to one PC, see the “DMZ” section.
To add a Customized Application using Port Range Forwarding:
1. Enter the name of the application in the appropriate Customized
Application field.
2. Next to the name of the application, enter the number of the external port
used by the server in the Ext. Port column. Check with the Internet application software documentation for more information.
3. On the same line, select Protocol TCP or Protocol UDP.
4. Enter the IP address of the server that you want the Internet users to be able

Static Routing
Figure 6-15
From the Dynamic Routing screen, shown in Figure 6-15, you can enable the
Router to automatically adjust to physical changes in the network’s layout. The
Router, using the RIP protocol, determines the network packets’ route based on
the fewest number of hops between the source and the destination. The RIP protocol regularly broadcasts routing information to other routers on the network.
To set up Dynamic Routing:
1. Choose the correct Working Mode. Gateway Mode should be used if the
Router is hosting your network’s connection to the Internet. Router Mode
should be selected if the Router exists on a network with other routers. In
Router Mode, any computer connected to the Router will not be able to connect to the Internet unless you have another router functioning in the
Gateway mode.
47
Figure 6-16
If the Router is connected to more than one network, it may be necessary to set
up a static route between them. This can be accomplished from the Static
Routing screen, shown in Figure 6-16. A static route is a pre-determined pathway that network information must travel to reach a specific host or network.
From the Static Routing tab, click the Show Routing Table button to view the
current static routing configuration.
2. Choose a Dynamic Routing path protocol for either transmission (TX:) or
reception (RX:) of network data by selecting Enabled.
To create a static route entry:
Click the Show Routing Table button to open a chart displaying how data is
routed through your LAN.

DMZ Host
From the DMZ Host screen, shown in Figure 6-17, you can expose one local
2. Enter the following data to create a new 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 here. 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 192.168.1.1. Based on this address, the address of the routed network is
192.168.1.x, with the last digit “x” determining the Router’s place on the
network. Therefore you would enter the IP address 192.168.1.0 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 an IP
address is the network portion, and which portion is the host portion. Take,
for example, a network in which the Subnet Mask is 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 IP address should be the IP address of the gateway
device that allows for contact between the Router and the remote network
or host.
Hop Count: This determines the maximum number of steps between network nodes that data packets will travel. A node is any device on the network, such as PCs, print servers, routers, etc. The maximum metric, or
measure, of hops is 15.
Interface: Select LAN or WAN, depending on the location of the static
route’s final destination.

Appendix A: Troubleshooting
Common Problems and Solutions
This appendix consists of two parts: “Common Problems and Solutions” and
“Frequently Asked Questions.” Provided are possible solutions to problems
regarding the installation and operation of the Router. If your situation is described
here, the problem should be solved by applying the corresponding solution. If you
can’t find an answer here, check the Linksys website at www.linksys.com.
1. I need to set a static IP address on a PC.
The Router, by default, assigns an IP address range of 192.168.1.100 to
192.168.1.149 using the DHCP server on the Router. To set a static IP address, you
can only use the ranges 192.168.1.2 to 192.168.1.99 and 192.168.1.151 to
192.168.1.254. 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 SE and Me:
A. Click Start, Settings, and Control Panel. Double-click Network.

C. Make sure you are using the right Internet 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 6: The Router’s Web-based Utility” for details on Internet settings.
D. Make sure you have the right cable. Check to see if the Internet column has
a solidly lit Link LED.
E. 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 interface shows a valid IP address from your ISP.
F. 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.
4. I am not able to access the Router’s web interface Setup page.
A. Refer to “Problem #2, I want to test my Internet connection” to verify that
your computer is properly connected to the Router.
B. Refer to “Appendix D: 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 #1: I need to set a
static IP address.”
D. Refer to “Problem #10: I need to remove the proxy settings or the dial-up
pop-up window (for PPPoE users).”
5. I can’t get my Virtual Private Network (VPN) working through the Router.
Access the Router’s web interface by going to http://192.168.1.1 or the IP
address of the Router, and go to the Advanced => Filter tab. Make sure you
have IPsec pass-through and/or PPTP pass-through 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.
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.
59
Wireless Cable/DSL Router
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 192.168.1.X (X is a number from 1 to 254)
and your local LAN IP address is 192.168.1.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 Setup tab
of the web interface. 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 #7, I need to set up online
game hosting or use other Internet applications” for details.
Check the Network Everywhere website for more information at www.networkeverywhere.com.
6. 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://192.168.1.1 or the
IP address of the Router. Go to the Advanced => Forwarding tab.
B. Enter any name you want to use for the Customized Application.
C. Enter the Ext. 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. Check the protocol you will be using, TCP and/or UDP.
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 192.168.1.100, you would enter 100 in the field provided. Check
“Appendix D: Finding the MAC Address and IP Address for Your Ethernet

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:
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.) Follow these steps to set DMZ hosting:
A. Access the Router’s web interface by going to http://192.168.1.1 or the IP
address of the Router. Go to the Advanced => Forwarding tab.
B. Enter any name you want to use for the Customized Application.
C. Enter the Ext. 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.
D. Check the protocol you will be using, TCP and/or UDP.
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 192.168.1.100, you would enter 100 in the field provided. Check

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 Internet to LAN.
Does the Router’s Internet port support 100 Mbps Ethernet? Because of the speed
limitations of broadband Internet connections, the Router’s current hardware
design supports 10 Mbps Ethernet on its Internet port. It does, of course, support 100 Mbps over its LAN ports.
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 SE,
Windows 2000, Windows NT, or Windows XP? Yes, but Network Everywhere
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 set67
Wireless Cable/DSL Router
ting. 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 ~ 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.
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 for about 30 seconds. 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 Network Everywhere website,
www.networkeverywhere.com.

like to use. Downloading a more current version of Router firmware will not
enhance the quality or speed of your Internet connection, and may disrupt
your current connection stability.
Will the Router function in a Macintosh environment? Yes, but the Router’s setup
pages are accessible only through Internet Explorer 4.0 or Netscape
Navigator 4.0 or higher for Macintosh.
I am not able to get the web configuration screen for the Router. What can I do?
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 D: 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.
69
How many ports can be simultaneously forwarded? Theoretically, the Router can
establish 520 sessions at the same time, but you can only forward 10 ranges
of ports.
Does the Router replace a modem? Is there a cable or DSL modem in the Router?
No, this version of the Router must work in conjunction with a cable or DSL
modem.
Which modems are compatible with the Router? The Router is compatible with
virtually any cable or DSL modem that supports Ethernet.
What are the advanced features of the Router? The Router’s advanced features
include IP Filtering, Port Range Forwarding, Dynamic Routing, Static
Routing, DMZ hosting, and MAC Address Cloning.
What is the maximum number of VPN sessions allowed by the Router?
The maximum number depends on many factors. At least one IPSec session
will work through the Router; however, simultaneous IPSec sessions may be
possible, depending on the specifics of your VPNs.
How can I check whether I have static or DHCP IP Addresses? Consult your ISP
to obtain this information.
How do I get mIRC to work with the Router? Under the Port Range Forwarding
tab, set port forwarding to 113 for the PC on which you are using mIRC.
Can the Router act as my DHCP Server? Yes. The Router has DHCP Server software built-in.
Can I run an application from a remote computer over the wireless network? This
will depend on whether or not the application is designed to be used over a
network. Consult the application’s documentation to determine if it supports
operation over a network.
What is the IEEE 802.11b standard? The IEEE 802.11b Wireless LAN standards
subcommittee formulates the standard for the industry. The objective is to
enable wireless LAN hardware from different manufacturers to communicate.
70
Network Everywhere® Series
What IEEE 802.11 features are supported? The product supports the following
IEEE 802.11 functions:
• CSMA/CA plus Acknowledge protocol
• Multi-Channel Roaming
• Automatic Rate Selection
• RTS/CTS feature
• Fragmentation
• Power Management
What is BSS ID? A specific Ad-hoc LAN is called a Basic Service Set (BSS).
Computers in a BSS must be configured with the same BSS ID.
What is SSID? An Infrastructure configuration could also support roaming
capability for mobile workers. More than one BSS can be configured as an
Extended Service Set (ESS). Users within an ESS could roam freely between
BSSs while maintaining a continuous connection to the wireless network stations and Access Points.
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. 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 tradeoff 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 spreadspectrum signal looks like background noise. There are two main variations,
Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread
Spectrum (FHSS).
Wireless Cable/DSL Router
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.
Would the information be intercepted while transmitting on air? WLAN features
two-fold protection in security. On the hardware side, as with Direct
Sequence Spread Spectrum technology, it has the inherent security feature of
scrambling. On the software side, the WLAN series offers the encryption
function (WEP) to enhance security and access control. Users can set it up
depending upon their needs.
What is WEP? WEP is Wired Equivalent Privacy, a data privacy mechanism
based on a 40/64 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 on to the
network, the MAC address of a device stays the same, making it a valuable
identifier for the network.

Appendix B: How to Ping Your ISP’s
E-mail and Web Addresses
Virtually all Internet addresses are configured with words or characters (i.e.,
www.networkeverywhere.com, www.yahoo.com, etc.) In actuality, however,
these Internet addresses are assigned to IP addresses, which are the true
addresses on the Internet.
IP and web addresses, however, can sometimes be long and hard to remember.
Because of this, certain ISPs will shorten their server addresses to single words
or codes on their users’ web browser or e-mail configurations. If your ISP’s email and web server addresses are configured with single words (“www,” “email,” “home,” “pop3,” etc.) rather than whole Internet Addresses or IP
Addresses, the Router may have problems sending or receiving mail and
accessing the Internet. This happens because the Router has not been configured by your ISP to accept their abbreviated server addresses.
The solution is to determine the true web addresses behind your ISP’s code
words. You can determine the IP and web addresses of your ISP’s servers by
“pinging” them.
Note: If you don’t have your ISP’s web and e-mail IP addresses, you must
either get them from your ISP or follow these steps prior to connecting the
Router to your network.
Step One: Pinging an IP Address
The first step to determining your ISP’s web and e-mail server address is to
ping its IP address.
1. Power on the computer and the cable or DSL modem, and restore the
network configuration set by your ISP if you have since changed it.
2. Click Start, then Run, and type “command.” This will bring up the DOS
window.
73
Wireless Cable/DSL Router
3. At the DOS command prompt, type “ping mail” (assuming that the location for which you’re trying to find an IP address is configured as “mail”).
Press Enter. Information such as the following data, taken from a ping of
Microsoft Network’s e-mail server, will be displayed.

4. Write down the IP address returned by the ping command. (In the
example above: 24.53.32.4.) This IP address is the actual IP address of the
server “mail,” or any other word or value you have pinged.
Step Two: Pinging for a Web Address
While the IP address returned above would work as your e-mail server address,
it may not be permanent. IP addresses change all the time. Web addresses, however, usually don’t. Because of this, you’re likely to have fewer problems by
configuring your system with web addresses rather than IP addresses. Follow
the instructions below to find the web address assigned to the IP address you
just pinged.
1. At the DOS command prompt, type “ping -a 24.53.32.4,” where
24.53.32.4 is the IP address you just pinged. Information such as the following data will be displayed.

2. Write down the web address returned by the ping command (in the
example above: mail.msnv3.occa.home.com.). This web address is the web
address assigned to the IP address you just pinged. While the IP address of
“mail” could conceivably change, it is likely that this web address will not.
3. Replace your ISP’s abbreviated server address with this extended web
address in the corresponding Internet application (web browser, e-mail
application, etc.).
Once you have replaced the brief server address with the true server address,
the Router should have no problem accessing the Internet through that Internet
application.

Appendix C: Configuring Wireless
Security
Note: WEP encryption is an additional data security measure and not essential for router operation.
An acronym for Wired Equivalent Privacy, WEP is an encryption method used
to protect your wireless data communications. WEP uses a combination of 64bit or 128-bit keys to provide access control to your network and encryption
security for every data transmission. To decode a data transmission, each point
in a network must use an identical 64-bit or 128-bit key. Higher encryption levels mean higher levels of security, but due to the complexity of the encryption,
they may mean decreased network performance.
You may also have heard the term “40-bit” used in conjunction with WEP
encryption. This is simply another term for 64-bit WEP encryption. This level
of WEP encryption has been called 40-bit because it uses a 40-bit secret key
along with a 24-bit Initialization Vector (40 + 24 = 64). Wireless vendors may
use either name. Network Everywhere uses the term “64-bit” when referring
to this level of encryption.
Make sure your wireless network is functioning before attempting to configure
WEP encryption.
A 128-bit WEP encrypted wireless network will NOT communicate with a 64bit WEP encrypted wireless network. Therefore, make sure that all of your
wireless devices are using the same encryption level. All wireless devices complying with the 802.11b standard will support 64-bit WEP.
In addition to enabling WEP, Network Everywhere also recommends the following security implementations:
• Changing the SSID from the default “wireless”
• Changing the WEP key regularly
Note: In order for WEP Encryption to be enabled, wireless functions must
first be enabled. Select Enable under the Wireless section before proceeding.

section.
2. Press the WEP Key Setting button to set the WEP Encryption type and
level.

•
WEP (64Bit or 128B) Select the level of encryption from the drop-down
box. 128-bit WEP encryption is unique to Network Everywhere and may
conflict with other vendors’ WEP encryption.
Note: In order to utilize WEP encryption, all points in your wireless
network must have WEP enabled and be set to the same Key Setting.
The WEP Encryption key is generated in one of two ways:
3. The screen displayed in Figure
C-1 may appear,
verifying that you
are enabling WEP
Encryption. Press
the OK button to
continue.
1. You may create an encryption key by using a Passphrase.
a. Enter a Passphrase, a user-defined password, into the Passphrase field.
The Passphrase can be a maximum of 31 letters, symbols, and numbers.
No spaces can be used.
Figure C-1
4. This will display the screen shown in Figure C-2. From this screen, you will
choose your WEP Encryption settings.
b. Click the Generate button to create a key. The key will be 10 digits if
you chose 64-bit encryption, or 26 digits if you chose 128-bit encryption.
This key will be used to encrypt and decrypt the data being sent between
the Router and your network’s wireless PCs.
The Key field may not display all digits. Using the mouse, click anywhere within the Key field. Move the cursor to the right to view the rest
of the Key. Make sure your write down the entire Key EXACTLY the
way it is displayed.
2. You may enter the encryption key manually.
Make a note of the Passphrase or Manual Key. You will need it for the other
wireless devices on the network, as the same WEP encryption key must be
entered in all wireless devices on the network.
Once you have chosen your key encryption method and entered either the
Passphrase or manual key, click the Apply button, and the encryption portion
of the setup is complete.
Note: In Windows XP, a 128-bit Key generated by the Router
will be called a "104 bits (26 digits)" key, and a 64-bit Key generated by the Router will be called a “40 bits (10 digits)” key.

Appendix E: Glossary
10BaseT - An Ethernet standard that uses twisted wire pairs.
100BaseTX - IEEE physical layer specification for 100 Mbps over two pairs of
Category 5 cable.
Adapter - Printed circuit board that plugs into a PC to add to capabilities or
connectivity to a PC. In a networked environment, a network interface card is
the typical adapter that allows the PC or server to connect to the intranet and/or
Internet.
Auto-negotiate - To automatically determine the correct settings. The term is
often used with communications and networking. For example, Ethernet
10/100 cards and switches can determine the highest speed of the node they are
connected to and adjust their transmission rate accordingly.
Bandwidth - The transmission capacity of a given facility, in terms of how
much data the facility can transmit in a fixed amount of time; expressed in bits
per second (bps).
Figure D-6
When entering information for MAC Address Cloning, type the 12-digit MAC
address (see Figure D-7).
Bit – A binary digit. The value—0 or 1—used in the binary numbering system.
Also, the smallest form of data.
Boot – To cause the computer to start executing instructions. Personal computers contain built-in instructions in a ROM chip that are automatically executed
on startup. These instructions search for the operating system, load it, and pass
control to it.
Bridge - A device that interconnects different networks together.
Broadband - A data-transmission scheme in which multiple signals share the
bandwidth of a medium. This allows the transmission of voice, data, and video
signals over a single medium. Cable television uses broadband techniques to
deliver dozens of channels over one cable.
Browser - A browser is an application program that provides a way to look at
and interact with all the information on the World Wide Web or PC. The word
“browser” seems to have originated prior to the Web as a generic term for user
interfaces that let you browse text files online.
Figure D-7
87
Cable Modem - A device that connects a computer to the cable television network, which in turn connects to the Internet. Once connected, cable modem
users have a continuous connection to the Internet. Cable modems feature
88
Network Everywhere® Series
asymmetric transfer rates: around 36 Mbps downstream (from the Internet to
the computer), and from 200 Kbps to 2 Mbps upstream (from the computer to
the Internet).
CAT 5 - ANSI/EIA (American National Standards Institute/Electronic
Industries Association) Standard 568 is one of several standards that specify
“categories” (the singular is commonly referred to as “CAT”) of twisted pair
cabling systems (wires, junctions, and connectors) in terms of the data rates
that they can sustain. CAT 5 cable has a maximum throughput of 100 Mbps and
is usually utilized for 100BaseTX networks.
CSMA/CD (Carrier Sense Multiple Access/Collision Detection) - The LAN
access method used in Ethernet. When a device wants to gain access to the network, it checks to see if the network is quiet (senses the carrier). If it is not, it
waits a random amount of time before retrying. If the network is quiet and two
devices access the line at exactly the same time, their signals collide. When the
collision is detected, they both back off and each waits a random amount of
time before retrying.
Data Packet - One frame in a packet-switched message. Most data communications is based on dividing the transmitted message into packets. For example,
an Ethernet packet can be from 64 to 1518 bytes in length.
Default Gateway - The routing device used to forward all traffic that is not
addressed to a station within the local subnet.
DHCP (Dynamic Host Configuration Protocol) - A protocol that lets network
administrators centrally manage and automate the assignment of Internet
Protocol (IP) addresses in an organization's network. Using the Internet’s set of
protocol (TCP/IP), each machine that can connect to the Internet needs a
unique IP address. When an organization sets up its computer users with a connection to the Internet, an IP address must be assigned to each machine.
Without DHCP, the IP address must be entered manually at each computer and,
if computers move to another location in another part of the network, a new IP
address must be entered. DHCP lets a network administrator supervise and distribute IP addresses from a central point and automatically sends a new IP
address when a computer is plugged into a different place in the network.
DHCP uses the concept of a “lease” or amount of time that a given IP address
will be valid for a computer. The lease time can vary depending on how long a
user is likely to require the Internet connection at a particular location. It’s especially useful in education and other environments where users change frequently. Using very short leases, DHCP can dynamically reconfigure networks
in which there are more computers than there are available IP addresses.
89
Wireless Cable/DSL Router
DHCP supports static addresses for computers containing Web servers that
need a permanent IP address.
DMZ - (DeMilitarized Zone) allows one IP address (or 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 address if
you want to use DMZ Hosting.
DNS - The Domain Name System (DNS) is the way that Internet domain
names are located and translated into Internet Protocol (IP) addresses. A
domain name is a meaningful and easy-to-remember “handle” for an Internet
address.
Domain - A subnetwork comprised of a group of clients and servers under the
control of one security database. Dividing LANs into domains improves performance and security.
Download - To receive a file transmitted over a network. In a communications
session, download means receive, and upload means transmit.
Dynamic IP Address - An IP address that is automatically assigned to a client
station in a TCP/IP network, typically by a DHCP server. Network devices that
serve multiple users, such as servers and printers, are usually assigned static IP
addresses.
Dynamic Routing - The ability for a router to forward data via a different route
based on the current conditions of the communications circuits. For example,
it can adjust for overloaded traffic or failing lines and is much more flexible
than static routing, which uses a fixed forwarding path.
Ethernet - IEEE standard network protocol that specifies how data is placed
on and retrieved from a common transmission medium. Has a transfer rate of
10 Mbps. Forms the underlying transport vehicle used by several upper-level
protocols, including TCP/IP and XNS.
Firewall - A firewall is a set of related programs, located at a network gateway
server, that protects the resources of a network from users from other networks.
(The term also implies the security policy that is used with the programs.) An
enterprise with an intranet that allows its workers access to the wider Internet
installs a firewall to prevent outsiders from accessing its own private data
resources and for controlling what outside resources to which its own users
have access.
Basically, a firewall, working closely with a router, examines each network
packet to determine whether to forward it toward its destination.

Network Everywhere® Series
Firmware - Code that is written onto read-only memory (ROM) or programmable read-only memory (PROM). Once firmware has been written onto the
ROM or PROM, it is retained even when the device is turned off.
ing the development and application of electrotechnology and allied sciences
for the benefit of humanity, the advancement of the profession, and the wellbeing of our members.”
Fragmentation - Breaking a packet into smaller units when transmitting over
a network medium that cannot support the original size of the packet.
The IEEE fosters the development of standards that often become national and
international standards. The organization publishes a number of journals, has
many local chapters, and has several large societies in special areas, such as the
IEEE Computer Society.
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.
FTP includes functions to log onto the network, list directories, and copy files.
It can also convert between the ASCII and EBCDIC character codes. FTP operations can be performed by typing commands at a command prompt or via an
FTP utility running under a graphical interface such as Windows. FTP transfers
can also be initiated from within a Web browser by entering the URL preceded
with ftp://.
Unlike e-mail programs in which graphics and program files have to be
“attached,” FTP is designed to handle binary files directly and does not add the
overhead of encoding and decoding the data.
Full Duplex - The ability of a device or line to transmit data simultaneously in
both directions.
Gateway – A device that interconnects networks with different, incompatible
communications protocols.
Half Duplex - Data transmission that can occur in two directions over a single
line, but only one direction at a time.
Hardware - Hardware is the physical aspect of computers, telecommunications, and other information technology devices. The term arose as a way to distinguish the “box” and the electronic circuitry and components of a computer
from the program you put in it to make it do things. The program came to be
known as the software.
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
browser.
IEEE - The Institute of Electrical and Electronics Engineers. The IEEE
describes itself as “the world's largest technical professional society—promot91
Wireless Cable/DSL Router
IP Address - In the most widely installed level of the Internet Protocol (IP)
today, an IP address is a 32-binary digit number that identifies each sender or
receiver of information that is sent in packets across the Internet. When you
request an HTML page or send e-mail, the Internet Protocol part of TCP/IP
includes your IP address in the message (actually, in each of the packets if more
than one is required) and sends it to the IP address that is obtained by looking
up the domain name in the Uniform Resource Locator you requested or in the
e-mail address you're sending a note to. At the other end, the recipient can see
the IP address of the Web page requestor or the e-mail sender and can respond
by sending another message using the IP address it received.
IPCONFIG - A utility that provides for querying, defining and managing IP
addresses within a network. A commonly used utility, under Windows NT and
2000, for configuring networks with static IP addresses.
IPSec (Internet Protocol Security) - IPSec is a developing standard for security at the network or packet processing layer of network communication. A big
advantage of IPSec is that security arrangements can be handled without
requiring changes to individual user computers.
ISP - An ISP (Internet service provider) is a company that provides individuals
and companies access to the Internet and other related services such as website
building and virtual hosting.
LAN - A local area network (LAN) is a group of computers and associated
devices that share a common communications line and typically share the
resources of a single processor or server within a small geographic area (for
example, within an office building).
Latency - The time delay between when the first bit of a packet is received and
the last bit is forwarded.
MAC Address - The MAC (Media Access Control) 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.
92
Network Everywhere® Series
Mbps (MegaBits Per Second) - One million bits per second; unit of measurement for data transmission.
mIRC - mIRC runs under Windows and provides a graphical interface for logging onto IRC servers and listing, joining, and leaving channels.
NAT - NAT (Network Address Translation) is the translation of an Internet
Protocol address (IP address) used within one network to a different IP address
known within another network. One network is designated the inside network
and the other is the outside.
Network - A system that transmits any combination of voice, video, and/or
data between users.
Packet Filtering - Discarding unwanted network traffic based on its originating address or range of addresses or its type (e-mail, file transfer, etc.).
Ping (Packet INternet Groper) - An Internet utility used to determine whether
a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response.
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.
Port - A pathway into and out of the computer or a network device such as a
switch or router. For example, the serial and parallel ports on a personal computer are external sockets for plugging in communications lines, modems, and
printers.
PPPoE (Point to Point Protocol over Ethernet) - PPPoE is a method for the
encapsulation of PPP packets over Ethernet frames from the user to the ISP
over the Internet. One reason PPPoE is preferred by ISPs is because it provides
authentication (username and password) in addition to data transport. A PPPoE
session can be initiated by either a client application residing on a PC, or by
client firmware residing on a modem or router.
PPTP (Point-to-Point Tunneling Protocol) - A protocol which allows the Point
to Point Protocol (PPP) to be tunneled through an IP network. PPTP does not
specify any changes to the PPP protocol but rather describes a “tunneling service” for carrying PPP (a tunneling service is any network service enabled by
tunneling protocols such as PPTP, L2F, L2TP, and IPSEC tunnel
93
Wireless Cable/DSL Router
RIP (Routing Information Protocol) - A simple routing protocol that is part of
the TCP/IP protocol suite. It determines a route based on the smallest hop count
between source and destination. RIP is a distance vector protocol that routinely broadcasts routing information to its neighboring routers.
RJ-45 - A connector similar to a telephone connector that holds up to eight
wires, used for connecting Ethernet devices.
Router - Protocol-dependent device that connects subnetworks together.
Routers are useful in breaking down a very large network into smaller subnetworks; they introduce longer delays and typically have much lower throughput
rates than bridges.
Server - Any computer whose function in a network is to provide user access
to files, printing, communications, and other services.
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.
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
(switch, 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.).
Software - Instructions for the computer. A series of instructions that performs
a particular task is called a “program.” The two major categories of software are
“system software” and “application software.” System software is made up of
control programs such as the operating system and database management system (DBMS). Application software is any program that processes data for the
user.
A common misconception is that software is data. It is not. Software tells the
hardware how to process the data.
Static IP Address - A permanent IP address that is assigned to a node in a
TCP/IP network.
Static Routing - Forwarding data in a network via a fixed path. Static routing
cannot adjust to changing line conditions as can dynamic routing.
94
Network Everywhere® Series
Subnet Mask - The method used for splitting IP networks into a series of subgroups, or subnets. The mask is a binary pattern that is matched up with the IP
address to turn part of the host ID address field into a field for subnets.
Switch – 1. A data switch connects computing devices to host computers,
allowing a large number of devices to share a limited number of ports. 2. A
device for making, breaking, or changing the connections in an electrical circuit.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the IP (Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), TCP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. TCP is known as a “connection oriented” protocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic communication language or set of protocols for communications over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of
protocols and not only TCP and IP.
Telnet - A terminal emulation protocol commonly used on the 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.
Wireless Cable/DSL Router
the actual delivery of the data (routing), UDP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the network. UDP is known as a “connection-less” protocol
due to NOT requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet (as opposed to TCP).
Upgrade - To replace existing software or firmware with a newer version.
Upload - To send a file transmitted over a network. In a communications session, upload means transmit, and download means receive.
URL (Uniform Resource Locator) - The address that defines the route to a file
on the Web or any other Internet facility. URLs are typed into the browser to
access Web pages, and URLs are embedded within the pages themselves to provide the hypertext links to other pages.
WAN (Wide Area Network) - A communications network that covers a relatively large geographic area, consisting of two or more LANs. Broadband communication over the WAN is often through public networks such as the telephone (DSL) or cable systems, or through leased lines or satellites. In its most
basic definition, the Internet could be considered a WAN.
WINIPCFG - Configuration utility based on the Win32 API for querying,
defining, and managing IP addresses within a network. A commonly used utility for configuring networks with static IP addresses.
Workgroup - Two or more individuals that share files and databases.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol
that has no directory or password capability.
Throughput - The amount of data moved successfully from one place to another in a given time period.
Topology - A network’s topology is a logical characterization of how the
devices on the network are connected and the distances between them. The
most common network devices include switches, routers, and gateways. Most
large networks contain several levels of interconnection, the most important of
which include edge connections, backbone connections, and wide-area connections.
TX Rate – Transmission Rate.
UDP (User Datagram Protocol) - A method (protocol) used along with the IP
(Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
