Preparing Your Network to Work with a Router

This appendix describes how to prepare your network to connect to the Internet through a router

and how to verify the readiness of your broadband Internet service from an Internet service

provider (ISP).

What You Need To Use a Router with a Broadband Modem

You need to prepare these three things before you begin:

Cabling and Computer Hardware

To use the router on your network, each computer must have an 802.11g or 802.11b wireless

adapter or an installed Ethernet Network Interface Card (NIC) and an Ethernet cable. If the

computer will connect to your network using an Ethernet NIC at 100 Mbps, you must use a

Category 5 (Cat 5) cable such as the one provided with your router. The cable or DSL broadband

modem must provide a standard 10 Mbps (10BASE-T) or 100 Mbps (100BASE-Tx) Ethernet

interface.

Computer Network Configuration Requirements

The router includes a built-in Web Configuration Manager. To access the configuration menus on

the router, your must use a Java-enabled Web browser program that supports HTTP uploads such

as Microsoft Internet Explorer or Netscape Navigator. Use Internet Explorer or Netscape

Navigator 4.0 or above.

Note:

If your computer was configured during the installation of a broadband modem, or

using instructions provided by your ISP, you may need to copy the ISP configuration

information for use in the configuration of your router. Write down this information

before reconfiguring your computers. Refer to

“Obtaining ISP Configuration

Information for Windows Computers” on page C-19

or

“Obtaining ISP Configuration

Information for Macintosh Computers” on page C-20

for further information.

Preparing Your Network to Work with a Router

For the initial setup of your router, you will need to connect a computer to the router. This

computer has to be set to automatically get its TCP/IP configuration from the router via DHCP.

Note:

For help with DHCP configuration, please use the

Windows TCP/IP Configuration Tutorials

on the Resource CD.

Internet Configuration Requirements

Depending on how your Internet service set up your account, you may need one or more of these

configuration parameters to connect your router to the Internet:

•

Host and Domain Names

•

ISP Login Name and Password

•

ISP Domain Name Server (DNS) Addresses

•

Fixed IP Address, which is also known as the Static IP Address

Where Do I Get the Internet Configuration Parameters?

There are several ways you can gather the required Internet connection information:

•

Your Internet service provides all the information needed to connect to the Internet. If you

cannot locate this information, you can ask your Internet service provider to provide it or you

can try one of the options below.

•

If you have a computer already connected to the Internet, you can gather the configuration

information from that computer.

—

For Windows 95/98/ME, open the Network control panel, select the TCP/IP entry for the

Ethernet adapter, and click Properties. Record all the settings for each tab page.

—

For Windows 2000/XP, open the Local Area Network Connection, select the TCP/IP entry

for the Ethernet adapter, and click Properties. Record all the settings for each tab page.

—

For Macintosh computers, record the settings in the TCP/IP or Network control panel.

•

You may also refer to the Resource CD or the

NETGEAR Router ISP Guide

, which provides

Internet connection information for many ISPs.

Once you locate your Internet configuration parameters, you may want to record them on the page

below.

Record Your Internet Connection Information

Print this page. Fill in the configuration parameters from your Internet Service Provider (ISP).

ISP Login Name:

The login name and password are case sensitive and must be entered exactly as

given by your ISP. Some ISPs use your full e-mail address as the login name. The Service Name is

not required by all ISPs. If you connect using a login name and password, enter the following:

Login Name: ______________________________

Password: ____________________________

Service Name: _____________________________

Fixed or Static IP Address:

If you have a static IP address, record the following information. For

example, 169.254.141.148 could be a valid IP address.

Fixed or Static Internet IP Address: ______

______

Gateway IP Address: ______

______

Subnet Mask: ______

______

ISP DNS Server Addresses:

If you were given DNS server addresses, fill in the following:

Primary DNS Server IP Address: ______

______

Secondary DNS Server IP Address: ______

______

Host and Domain Names:

Some ISPs use a specific host or domain name like

CCA7324-A

or

home

. If you have not been given host or domain names, you can use the following examples as a

guide:

•

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

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

•

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

ISP Host Name: _________________________

ISP Domain Name: _______________________

For Wireless Access:

See the configuration worksheet in the

Resource Manual

for your

NETGEAR wireless equipment.

Preparing Your Network to Work with a Router

Preparing Your Computers for TCP/IP Networking

Computers access the Internet using a protocol called TCP/IP (Transmission Control Protocol/

Internet Protocol). Each computer on your network must have TCP/IP installed and selected as its

networking protocol. If a Network Interface Card (NIC) is already installed in your computer, then

TCP/IP is probably already installed as well.

Most operating systems include the software components you need for networking with TCP/IP:

•

Windows

®

95 or later includes the software components for establishing a TCP/IP network.

•

Windows 3.1 does not include a TCP/IP component. You need to purchase a third-party TCP/

IP application package such as NetManage Chameleon.

•

Macintosh Operating System 7 or later includes the software components for establishing a

TCP/IP network.

•

All versions of UNIX or Linux include TCP/IP components. Follow the instructions provided

with your operating system or networking software to install TCP/IP on your computer.

In your IP network, each computer and the router must be assigned unique IP addresses. Each

computer must also have certain other IP configuration information such as a subnet mask

(netmask), a domain name server (DNS) address, and a default gateway address. In most cases,

you should install TCP/IP so that the computer obtains its specific network configuration

information automatically from a DHCP server during bootup.

The router is shipped preconfigured as a DHCP server. The router assigns the following TCP/IP

configuration information automatically when the computers are rebooted.

These addresses are part of the IETF-designated private address range for use in private networks.

Configuring Windows 95, 98, and Me for TCP/IP Networking

As part of the computer preparation process, you need to manually install and configure TCP/IP on

each networked computer. Before starting, locate your Windows CD; you may need to insert it

during the TCP/IP installation process.

Installing or Verifying Windows Networking Components

To install or verify the necessary components for

IP networking:

1.

On the Windows taskbar, click the Start

button, point to Settings, and then click

Control Panel.

2.

Double-click the Network icon.

The Network window opens and displays a list

of installed components.

3.

Make sure that the following components are

installed:

•

Client for Microsoft Networks

•

Ethernet Adapter

•

TCP/IP

4.

The Primary Network Logon should be set to

Client for Microsoft Networks.

5.

If any of these items needs to be installed,

follow the steps below.

Note:

It is not necessary to remove any other network components shown in the Network

window in order to install the adapter, TCP/IP, or the Client for Microsoft Networks.

Installing a New Adapter

If you need to install a new adapter, follow these steps:

a.

Click the Add button.

b.

Select Adapter, and then click Add.

c.

Select the manufacturer and model of your Ethernet adapter, and then click OK.
