Introduction

DSL Modem Internet Gateway DG814

Thank you for purchasing a NETGEAR DG814 DSL Modem Internet Gateway. With this
gateway you can have secure Internet access through its high-speed ADSL modem and share
this modem with several computers.

This installation guide shows you how to connect the gateway and configure it and your
computers for secure Internet access. Setup is easy—follow the instructions in this guide and
your system will be up and running quickly.

With Auto Uplink™ on each network port, you don’t have to worry about which type of Ethernet
cable you use when you connect your computers, servers, or other network devices to the gateway.
Each network port automatically configures itself correctly when you plug in the cable.

If you have problems, there is a troubleshooting section on pages 11 and 12 to help you. You
can get more detailed troubleshooting information from the Reference Manual on the CD,
online at www.NETGEAR.com, or by phone. There’s a short glossary available on page 13 if
you have questions about terminology and a more extensive glossary in the Reference Manual.

Installation Overview

Estimated time: 15 to 30 minutes

1. Gather the configuration information you have for your Internet account from your
Internet Service Provider (ISP).

2. Connect the gateway to one computer.

3. Configure that computer to work with the gateway and restart the computer and gateway.

4. Configure the gateway and go online to test the connection.

5. Connect other computers, configure them and restart each. (optional)

6. Configure for content filtering or port forwarding. (optional)

On the DG814 Resource CD, you’ll find the DG814 Installation Assistant, which supplements
the instructions in this installation guide by animating the step-by-step procedures given here.
For more detailed information about installation, troubleshooting and configuration
procedures, see the Reference Manual on the CD.

Before installing the DG814 gateway, you should have active DSL service and an Internet account
with an Internet Service Provider (ISP).

For each computer that you want to connect to the gateway, you must have

• An available RJ-45 Ethernet port (or adapter) — either built-in or from a network

• TCP/IP networking installed.

• Windows® computers: Client for Microsoft® Networks software installed.

• A Category 5 (Cat 5) Ethernet patch cable

interface card (NIC) installed in the computer.

Note: If you have a built-in modem or a modem card, the telephone jack for the
modem looks very similar to an RJ-45 Ethernet port, but the RJ-45 port is larger.

Note: TCP/IP and Client for Microsoft Networks is installed on most Windows
computers. If you have viewed Web sites with a browser, you are ready to go.
Please see the
Windows computer.

Note: There is one cable in the box with the gateway.

Connection information

Later in the setup process you’ll use a Configuration Utility to configure the gateway to work
with your network and, at that time, you’ll need to know the type of account you have your
ISP and specific account information.

The next page includes blanks for you to fill in and refer to later.

Note: Your ISP should have provided you with a summary sheet of all the
information needed to connect your computer to the Internet. If you cannot locate
the information, you’ll have to contact your ISP.

Host and Domain Names

Some ISPs use a specific host or domain name—like CCA7324-A or home. If you haven’t
been given specific information about host or domain names then use the following examples
as a guide:

• If your main e-mail account with your ISP is [e-mail], then use aaa as your host

name. (Your ISP might call this your account, user, host, computer or system name.)

• If your ISP’s mail server is mail.xxx.yyy.com, then use xxx.yyy.com as the domain name.

Account name:

Domain name:

Login Name

If your ISP requires a login name and password (possibly because you have a PPPoE or PPPoA
account), fill in the following:

Login name: (may be your full e-mail address)

Password:

Service name: (if required by your ISP)

Note: The login name could be called a user name or account name by your ISP.
The login name is case sensitive. You must type it
example, c_jones is a different login name than C_Jones or cjones.

After unpacking the box and locating the configuration
information, you can install the gateway.

Note: You do not have to power down any
equipment to do this, but if you need to move your
computers (perhaps to get to ports in the back),
you may want to shut down the computers before
moving them.

1. Connect the microfilter splitter into the telephone
wall jack.

2. Connect a phone cord between the DSL port and
one of the smaller connector ports on the gateway.

3. Use an Ethernet cable to connect the computer to one of the four numbered Ethernet
ports on the gateway.

4. To use a telephone with this wall jack, connect a phone cord into the Phone port.

5. Connect the power adapter into the back of the gateway and then plug the adapter into a
power source (such as a wall socket or power strip).

Note: If you want to connect other computers into the gateway, don’t connect them
now. Do that after you know that the gateway setup works with one computer.

4. Turn the gateway’s power on.

Note: If you don’t want to connect a telephone at the wall jack, you may connect the
gateway directly to the wall jack with a phone cord. You can connect a telephone to
the gateway by placing a microfilter between the gateway and the telephone’s cord.

Check the setup

• The Test light turns on for a few seconds and then goes off.

Note: If the Test light stays on or blinks, go to Troubleshooting on page 11.

• The Power and Internet lights should be lit.

• The number of the port with the computer (if powered up)

should be lit and may blink to show network activity.

Note: If the connection is a 100 Mbps connection, the number is green. If it is a
10 Mbps connection, the number is yellow. If either the
number light isn’t lit, go to

Troubleshooting on page 11.

Troubleshooting

No lights are lit on the gateway

The gateway has no power.

• Make sure the power adapter is properly connected to the gateway.

• Make sure the power adapter is properly connected to a functioning power outlet. If it’s in

a power strip, make sure the power strip is turned on.

• Make sure the power switch in the back is in the On position.

Test light remains lit

After you plug in the power adapter and turn on the gateway, the Test light
should turn on and then, after approximately 10 seconds, turn off.

• If the Test light does not turn off, turn off the gateway and then turn
it on again. Contact NETGEAR if this doesn’t solve the problem.

The Internet light doesn’t light up

The Power light and at least one numbered light is lit, but the Internet
light isn’t lit.

• You may not have active DSL service yet. Contact your provider to
verify activation.

There is no numbered light lit for a connected device

There’s a hardware connection problem.

• Make sure the cable connectors are securely plugged in at the gateway and the device.

• Make sure the connected device is turned on.

I cannot get onto the Internet with a computer

You may not have restarted the computer or the network to have TCP/IP changes take effect.

• Restart the computer.

• Turn off the gateway, and then restart the network. See Restarting the Network on page 7.

Your computer may not recognize any addresses.

• If you typed in addresses of one or two DNS servers when you configured the gateway,
restart your computer. Open the gateway’s Configuration Utility and verify that the DNS
addresses appear by clicking Advanced and then click LAN.

Your computer may not have the correct TCP/IP settings to recognize the gateway.

• Restart the computer and check that you have TCP/IP set up properly .

11

For Windows, the Network Properties should have Obtain an IP address automatically
selected (see page 6). For Macintosh computers, the TCP/IP (or Network) control panel
should be set to Using DHCP Server (see page 7).

• You may also verify that the gateway’s local IP address is 192.168.0.1. The computer’s IP
address should be between 192.168.0.2 and 192.168.0.254.

Your gateway might not be able to obtain a IP address from the ISP.

1. Start your browser, type the address for an external site (like www.NETGEAR.com),
and press Enter (Windows) or Return (Macintosh).

2. Go to the gateway’s Configuration Utility by going to http://192.168.0.1.

3. In the User ID box type admin, in the Password box type password, and click OK.

4. Click MAINTENANCE and then click SYSTEM STATUS.

5. Check that an IP address is shown for the WAN Port.
If you see 0.0.0.0, contact your ISP to get current configuration information.

Resetting TCP/IP Properties (Windows)
