Features
EtherFast®Cable/DSL Router with QoS and 8-Port Switch

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),
which 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 interacts
with your private Local Area Network (LAN) of PCs. The other, public side
interacts with 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 ho w y our network remains private. The Router protects y our network by inspecting every data packet coming
in through the WAN port before delivery to the f inal 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 the Router’s ports connect to two sides. Your 10/100 LAN
port(s) connect to the LAN, and the Internet WAN port connects to the WAN.
The LAN port(s) transmit data at 10 Mbps or 100 Mbps, whereas the broadband port, or WAN por t, 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 wa ys of assigning an IP address to y our netw ork de vices. You can
assign static IP addresses or use the Router to assign IP addresses dynamically.
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 ensures 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.

IP Addresses
EtherFast®Cable/DSL Router with QoS and 8-Port Switch
By default, the Router can act as a DHCP server for your LAN. 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 the Router, see the DHCP section in “Chapter 6: The Router’s Webbased Utility.”
This user guide covers the basic steps for setting up a network with the Router.
After going through “Chapter 2: Getting to Know the EtherFast Cable/DSL
Router with QoS and 8-Port Switch,” most users will only need to use the following chapters:
• Chapter 3: Connect the Router
This chapter instructs you on how to connect a cable or DSL modem to the
Router and connect your PC(s) to the Router.
• Chapter 4: Configure the PCs
This chapter instructs you on how to configure your PC(s) for a DHCP connection, if the network settings are not already set to DHCP.
• Chapter 5: Configure the Router
This chapter explains how to configure the Router using your web browser
and the Router’s web-based utility. You will configure the Router using the
settings provided by your ISP.
When you’re finished with the basic steps, then you are ready to connect to the
Internet. After the PC(s) can access the Internet through the Router, you can
alter the Router’s settings further; for example, you can adjust security features
and other settings to enable online gaming.

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
address is not within the DHCP range of the LAN IP Addresses.
If the dynamic IP addressing fails to provide a dynamic IP address,
refer to “Appendix A: Troubleshooting.”
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 that 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 tempor aril yassigned to the PC or device. After a certain
time period, they expire and may change. If a PC logs onto 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 a dedicated, high-speed connection type called Point to Point Protocol over Ether net (PPPoE). PPPoE is
similar to a dial-up connection, but PPPoE does not dial a phone number when
establishing a 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.
A DHCP server can either be a designated PC on the network or another network device, such as the Router. By default, the Router’s WAN setting is DHCP
client.
Note: Since the Router is a device that connects two networks, it
needs two IP addresses—one for the LAN, and one for the WAN. 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.
Howe v er, even this WAN IP address can be blocked, so that the Router
and network seem invisible to the Internet—see the Blocking WAN
Requests description under IP Filtering in “Chapter 6: The Router’s
Web-based Utility.”

Power Green. The Power LED lights up when the Router is powered
on.
QoS Green. The QoS LED lights up when the QoS feature is
active.
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. If the LED is flickering, the Router is actively sending or receiving data over that
port.

The Router’s por ts, where network cables are connected, are located on the
Router’s back panel.
WAN The WAN (Wide Area Network) port is where you
connect your cable or DSL modem through an
Ethernet cable. Your modem connection will not
work from any other port.
Ports 1-8 These eight LAN (Local Area Network) ports con-
nect to network devices, such as PCs, print servers,
and network attached storage (NAS). Each of the
ports will auto-detect whether a straight-through or
crossover cable is plugged into it, so there is no need
for an uplink port. Any one of the eight ports can
serve as an uplink port to other network devices.
Power The Power port is where you will connect the
power adapter.

The Reset Button
The Reset button can be used in one of two ways:
1. If the Router is having problems connecting to the Internet, press the Reset
button for just a moment with a paper clip or a pencil tip. This clears up any
jammed connections, and is similar to pressing the Reset button on your PC
to reboot it.
This will reboot the Router while keeping all of the Router’s settings.
2. If you are experiencing extreme problems with the 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 settings such as IP addresses or a new password.

Chapter 3:Connect the Router
Unlike a hub or a switch, the Router’s setup consists of more than simply plugging hardware together. You will have to configure your networked PCs to
accept the IP addresses that the Router assigns them (if applicable), and you
will also have to configure the Router with setting(s) provided by your Internet
Service Provider (ISP).
The installation technician from your ISP should have left the setup information for your modem with you after installing your broadband connection. If
not, you can call your ISP to request the data.
Once you have the setup information you need for y our specific type of Internet
connection, you can begin installation and setup of the Router.

Full/Col Green. The Full/Col LED also serves two purposes. If this
LED is lit up solidly, the connection made through the corre-
sponding port is running in Full Duplex mode. If the LED
flickers, the connection is experiencing collisions (when two
PCs send data at the same time). Infrequent collisions are
normal.
If this LED flickers continuously, 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 100Mbps
connection is made through the corresponding port.
If this LED does not light up, then your connection speed is
10 Mbps.
The WAN Indicators
Link Green. The Link LED lights up when a successful connec-
tion is made between the Router and your cable or DSL
modem or WAN.
Act Green. The Act LED flickers when the Router is sending or
receiving data over the WAN port.
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 one minute or longer, see “Appendix
A: Troubleshooting.”

• The Power LED on the front panel will light up green 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 tur n 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 turns off. This
will restore the Router’s factor y default settings.
The Router’s hardware installation is now complete.
Go to “Chapter 4: Configure the PCs.”
1. Before you begin, make sure that all of your network’s hardware is powered
off, including the Router, PCs, and cable or DSLmodem.
2. Connect one end of
an Ethernet cable to
one of the LAN
ports (labeled 1-8)
on the back of the
Router, and the
other end to a standard port on a network device, 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 netw ork devices to the Router.
3. Connect the Ethernet cable from your cable or DSL
modem to the WAN port on the 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.
Connecting Your Hardware Together and Booting Up
Note: It is highly recommended that you
plug the Router’s power adapter into a
power strip with surge protection.
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 hardw are is powered on properly. Verify that the modem is plugged into the WAN
port on the Router.

Chapter 4: Configure the PCs
The instructions in this chapter will help you configure each of your computers to be able to communicate with the Router.
To do this, y ou need to configure your PC’s network settings to obtain an IP (or
TCP/IP) address automatically (called DHCP). Computers use IP addresses to
communicate with each other across a network, such as the Internet.
Find out which Windows operating system your computer is running. You can
find out by clicking the Start button and then selecting the Settings option.
Then click Control Panel, and double-click the System icon. If your Start
menu doesn’t have a Settings option, you’re running Windows XP. Click the
Cancel button when done.
You may 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 network settings based on the type of Windows operating system you are using. Make sure
that an Ethernet card or adapter (also known as a network adapter) has been
successfully installed in each PC you will configure. Once you’ve configured
your computers, continue to “Chapter 5: Configure the Router.”
