Chapter 2:Getting to Know the
4-Port EtherFast®Cable/DSL
Router
Your Router’s ports, where network cables are connected, are located on the
rear panel of your Router.
WAN The WAN (Wide Area Network) port is where you
connect your RJ-45 Internet connection through a
cable or DSL modem. Your modem connection
will not work from any other port.
Ports 1-4 These four LAN (Local Area Network) ports con-
nect to network devices, such as PCs, print servers,
and remote hard drives. If Port 1 is being used, the
Uplink port will not work because these two shared
ports have internally shared wiring.
Uplink The Uplink port is used to expand your network by
connecting to another switch or hub. Uplinking to a
switch or a hub is done by simply running a cable
from the Uplink port to the other device. See the
Uplinking: Connecting More Devices to the Router
section for more on uplinking.
If the Uplink port is being used, Port 1 will not
work.
Powe r The Power port is where you will connect the
power adapter.

The WAN Indicators
Link Green. The Link LED lights up when a successful connec-
tion is made between the Router and your broadband device
or network.
Act Green. The Act LED flickers when the Router is sending or
receiving data over the broadband WAN port (to the
Internet).
Diag Red. The Diag LED lights up when the Router goes through
its self-diagnosis mode during every boot-up. It will turn off
upon successful completion of the diagnosis.
If this LED stays on for an abnormally long period of time,
see “Appendix A: Troubleshooting.”
The Reset Button
*
The Reset button can be used in one of two ways.
1. If your Router is having prob lems connecting to the Internet, press the Reset
button for just a moment with a paper clip or a pencil tip. This clears up an y
jammed connections, and is similar to pressing the Reset button on your PC
to reboot it.
2. If you are experiencing extreme problems with your Router and have tried
all other troubleshooting measures, press the Reset Button and hold it down
until the red Diag LED on the front panel turns on and off completely.
This will restore factory defaults and clear all of the Router’s settings, including the IP addresses you entered.
* The Reset Button is located on the front panel of the 4-Port Router, and the rear panels of the 3-
Port Router and the 1-Port Router.
Power Green. The Power LED lights up when the Router is powered
on.
Link/Act Green. The Link/Act LED ser ves two purposes. If the LED
is continuously lit, the Router is successfully connected to a
device through the corresponding port (1, 2, 3 or 4). If the
LED is flickering, the Router is actively sending or receiving
data over that port. Port 1 is lit when using the Uplink port.
Full/Col Green. The Full/Col LED also serves two purposes. If this
LED is lit up continuously, the connection made through the
corresponding port is r unning in Full Duplex mode. If the
LED flickers, the connection is experiencing collisions.
Infrequent collisions are normal.
If this LED flickers too often, there may be a problem with
your connection. See “Appendix A: Troubleshooting” if you
encounter this problem.
100 Orange. The 100 LED lights up when a successful 100 Mbps
connection is made through the corresponding port.
If this LED does not light up, then your connection speed is
10 Mbps.

The Crossover Switch
When “uplinking,” or connecting two pieces of network hardware together,
such as a hub and a switch, a general rule of thumb is to plug one end of a
network cable into a straight-through port, and the other end into a crossover
port. Standard ports are straight-through ports, and uplink por ts are crossover
ports.

are made, and where you can reset or configure the Router’s LAN port.
WAN The WAN (Wide Area Network) port is where you
connect your RJ-45 Internet connection through a
cable or DSL modem. Your modem connection
will not work from any other port.
LAN The LAN (Local Area Network) por t is where you
connect your Router to a PC, hub, or switch. If you
have more than one PC, connect an Ethernet hub or
switch to your Router, and then connect your PCs to
that hub or switch.

Link/Act Green. The Link/Act LED ser ves two purposes. If the LED
is continuously lit, the Router is successfully connected to a
device through the LAN port. If the LED is flickering, the
Router is actively sending or receiving data through the LAN
port.
Full/Col Green. The Full/Col LED also serves two purposes. If this
LED remains lit, a LAN port connection is being successfully maintained. If the LED flickers, the connection is experiencing collisions. Infrequent collisions are normal.
If this LED flickers too often, there may be a problem with
your connection. See “Appendix A: Troubleshooting” if you
encounter this problem.
10/100 Orange. The 10/100 LED lights up when a successful
100 Mbps connection is made through the corresponding
port.
If a connection is running at 10 Mbps, the 10/100 LED will
not light up.
The WAN Indicators
Link Green. The Link LED lights up when a successful connec-
tion is made between the Router and your broadband device
or network.
Act Green. The Act LED flickers when the Router is sending or
receiving data over the broadband WAN port.

3-Port EtherFast Cable/DSL
Router
Ports 1-3 These three LAN por ts connect to your PCs, hubs,
switches, print servers, or any other devices with an
Ethernet port.
Uplink The Uplink por t connects to another hub or switch
for port expansion when you run out of open ports
for your network devices. Since the Uplink port and
the standard port right next to it share internal wiring,
you can only use one of the two ports at a time.
WAN The WAN (Wide Area Network) port is where you
connect your RJ-45 Internet connection through a
cable or DSL modem. Your modem connection
will not work from any other port.
Power The Power port is where you will connect the
power adapter.
USB The USB port (Type B - slave) can connect to a
USB-ready PC or a USB hub. This allows you to
enjoy an immediate, plug-and-pla y connection without even installing a network adapter for your PC.
To work with USB ports, your PC must be running
Windows 98, 2000, Millennium, or XP.

LED does not light up, then your connection speed is
10 Mbps.
This USB icon denotes the presence of a USB port or connector.
Your 3-Port Router comes with a USB cable that has tw o dif ferent types of connectors. Type A, the master connector, is shaped like a rectangle and plugs into
your PC’s USB port. Type B, the slave connector, resembles a square and connects to the USB port on the rear panel of your Router.
USB Compatibility with Your PC
To use the USB port on the 3-Port Router, you must have Windows 98, 2000,
Millennium, or XP installed on your PC. USB cannot run in a Windows 95 or NT
environment.
Also, your PC must hav e a USB port installed and enabled. Some PCs may have a disabled USB port. If your port doesn’t seem to be working, there may be jumpers on the
motherboard or a menu option in the BIOS to enable a PC’s USB port.
Other motherboards have USB interfaces, but no ports. You can purchase and install
a USB-ready card at your local computer store. See your PC’s user guide for instructions.

Chapter 5:Connecting the
Cable/DSL Router to Your Network
Unlike a hub or a switch, the Cable/DSL Router’s setup consists of more than
simply plugging hardware together. Since the Router acts as a DHCP server,
you will have to set some values for the Router and also configure your networked PCs to accept the IP addresses that the Router assigns them.
If you use a static IP address to connect to the Inter net, you will need the following data from your Internet Service Provider (ISP) to install the Router:
• Your broadband-configured PCs’ Computer Name and Workgroup Name
• Your broadband-configured PCs’fixed
Internet IP Address
• Your Subnet Mask
• Your Default Gateway
• Your Primary DNS Server IP address(es)
The installation technician from your ISP should hav e left this information with
you after installing your broadband connection. If not, you can call your ISP to
request the data. Otherwise, most ISPs will automatically assign an IP address
and other information to connect to the Internet.
Once you have the above values, you can begin the installation and setup of
your EtherFast Cable/DSL Router.
Simply put, a router is a network device that connects two networks together.
In this instance, your EtherFast Cable/DSL Router connects your Local Ar ea
Network (LAN), or the group of PCs in your home or of fice, to the Wide Area
Network (WAN), that is, the Internet. Your Router processes and regulates the
data that travels between these two networks.
Think of your Router as a network device with two sides: the first side is made
up of your private Local Area Network (LAN) of PCs, which this User Guide
sometimes calls the “internal LAN.” The other, public side is the Internet, or
the Wide Area Network (WAN), outside of your home or office.

If you use your 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 your Router. You
can get the information from your ISP.
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 (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
PCs and other network devices using dynamic IP addressing are assigned a ne w
IP address by a DHCP server. The PC or network device obtaining an IP
address is called the DHCP client. DHCP frees you from having to assign IP
addresses manually every time a new user is added to your network.
DHCP servers can either be a designated PC on the network or another netw ork
device, such as the Cable/DSL Router. The Router’s WAN por t, by default, is
set as a DHCP client.
By factory default, a DHCP server (LAN side) is enabled on your Router. 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 DHCP on your Router, see the DHCP section in “Chapter 8: The
Cable/DSL 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.
If the dynamic IP addressing fails to provide a dynamic IP address for
any reason, please refer to “Appendix A: Troubleshooting.”
Your Router’s firewall (NAT) protects your network of PCs so users on the public, Internet side cannot “see” your PCs. This is how your internal LAN, or
network, remains private. The Router protects your network by inspecting the
first packet coming in from the WAN 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.
Remember that your Router’s ports connect to two sides: your 10/100 LAN
port(s) and the Internet WAN port. The LAN port(s) transmit data at 10 Mbps
or 100 Mbps, whereas the broadband port, or WAN port, transmits data at
10 Mbps.
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 WAN 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 f ixed 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 always
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.
Note: Since your Router is a device that connects two networks, it
needs two IP addresses—one for the LAN side, and one for the WAN
side. In this User Guide, you’ll see references to the “WAN IP
address” and the “LAN IP address.”
Since the Router has firewall security (NAT), the only IP address that
can be seen from the Internet for your network is the Router’s WAN IP
address.
However, even this WAN IP address for the Router can be blocked, so
that your Router and network seem invisible to the Internet—see the
Blocking WAN Requests description under IP Filtering in “Chapter 8:
The Cable/DSL Router’s Web-based Utility.”

3. Connect the network cable from your cable or DSL modem to the WAN
port on your Router’s rear panel. This is the only port that will work for your
modem connection.
4. Connect the power adapter to the Power port on the rear panel of the
Router, and then plug the power adapter into a power outlet.
• The Power LED on the front panel will light up g reen as soon as the power
adapter is connected properly.
• The Diag LED will light up red for a few seconds when the Router goes
through its self-diagnostic test. This LED will turn off when the self-test is
complete.
5. Power on the cable or DSL modem.
6. Press the Reset button on the Router’s front panel with a paper clip or a
pencil. Hold the button in until the Diag LED lights up and then tur ns off.
This will restore the Router’s factory def ault settings.
The Router’s hardware installation is now complete.
Note: It is highly recommended that you plug your Router’s
power adapter into a power strip with surge protection.
1. Before you begin, make sure that all of your hardware is powered off,
including your Router, PCs, hubs, switches, and the cable or DSL modem.
2. A. If you hav e the 4-P ort Cab le/DSL Router, connect one end of a netw ork
cable to one of the LAN ports (labeled 1, 2, 3, or 4) on the back of the
Router, and the other end into a standard port on a network de vice, e.g., a PC,
print server, hub, or switch. See “Appendix E: Twisted-Pair Cabling” for
details on network cabling.
Repeat the above step to connect more PCs or network devices to the Router.
2. B. If you have the 1-Port Router, connect one end of a network cable to
the LAN port on the back of the Router, and the other end into a port on a
network device, e.g., a PC, hub, or switch. If you are using Port 4 to connect
to a PC, set the Crossover switch to straight-through mode ( || ). If you are
connecting the Router to a hub or switch, please refer to the chart shown in
Figure 5-1 when setting the Crossover Switch.
2. C. If you have the 3-Port Cable/DSL Router, connect one end of a net-
work cable from the Router’s LAN ports (labeled 1, 2, or 3) to a network
adapter port on a PC, hub, switch, or other network device.
The 3-Port Router features one USB plug-and-play port that connects
instantly to any USB-ready PC or USB hub. This allows you to connect to
and access your Router without even installing any network adapter cards.
Note: A standard port is any port other than the WAN port and
the Uplink port on the Router. It’s a straight-through port.
Connecting Your Hardware Together and Booting Up
Have you checked that the Link/Act LEDs for all your LAN con-
nections and the Link LED for your WAN connection light up?
If all of your Link LEDs are not lighting up, make sure that all your
cables are securely plugged in, and that all of your hardware is powered on properly.

port. Now that all of your Router’s hardware is connected together, you must
enable the PC that will connect to the Router through its USB port.
Since your USB connection acts as a network adapter for your PC, there’s no
need for you to install a network adapter for that PC. Just follow the directions
below to enable your PC’s USB connection to the Router:
• If you are running Windows 98, continue on this page, below.
• For other Windows operating systems, please refer to the appropriate section
as listed in the Table of Contents.
You can also connect your Router’s USB port to other USB devices besides
USB-ready PCs, such as a USB hub using a USB cable.
1. With the Router connected to your PC’s USB port using a USB cable, start
up your PC in Windows 98 and insert the driver disk.
2. Windows will display a message notifying you that it has detected new hardware. Click the Next button.
Note: After you finish this conf iguration, make sure that TCP/IP is
installed on your PC(s). For instructions on installing TCP/IP, see
“Appendix D: Installing the TCP/IP Protocol.”
If your Router’s LAN ports are all full and you still have PCs and/or devices to
connect, connect a hub or a switch to your Router using a network cable.
To do so, use the Router’s Uplink port to connect to a standard port on a hub
or switch. If you have a PC/device connected to the port right next to the
Uplink port (on the 3- and 4-Port Routers), disconnect that PC/device and plug
it into an open port on the new hub or switch.
Since the Uplink port shares inter nal wiring with the port right next to it, you
can only use one of these two ports at a time; these ports are called shared
ports.
If your new hub or switch also has an Uplinkport, it too can be uplinked when
you run out of ports, and so on.
Use the Router’s Uplink por t to connect to a standard por t on a hub or switch.
This leaves you with new, open por ts on the hub or switch, to which you can
add more PCs and/or network devices.
See your nearest Linksys retailer or visit www.linksys.com for complete prod-
uct lines of 10/100 Mbps hubs and switches.
