Verifying TCP/IP Properties for Macintosh Computers

After your Macintosh is configured and has rebooted, you can check the TCP/IP configuration by

returning to the TCP/IP Control Panel. From the Apple menu, select Control Panels, then TCP/IP.

The panel is updated to show your settings, which should match the values below if you are using

the default TCP/IP settings that NETGEAR recommends:

•

IP addresses—192.168.0.2 through 192.168.0.253

•

The subnet mask is 255.255.255.0

•

The default gateway is 192.168.0.1

If you do not see these values, you may need to restart your Macintosh or you may need to switch

the “Configure” setting to a different option, then back again to “Using DHCP Server”.

Verifying the Readiness of Your DSL Internet Account

For access to the Internet, you need to contract with an Internet service provider (ISP) for a

single-user Internet access account using a DSL modem.

For a single-user Internet account, your ISP supplies TCP/IP configuration information. With a

typical account, much of the configuration information is dynamically assigned when your

computer is first booted up while connected to the ISP, and you will not need to know that dynamic

information.

Are Login Protocols Used?

Some ISPs require login protocol which requires you to enter a login name and password in order

to access the Internet. If you run a program such as WinPOET or EnterNet to connect to your

Internet account, then your account uses PPP over Ethernet (PPPoE).

If login protocols are used, you can configure your modem to operate in router mode. After the

modem is configured, it will perform the login task when needed, and you will no longer need to

run the login program from your computer. It is not necessary to uninstall the login program.

If you prefer to run the software on your computer which performs the login, you can do so by

configuring the modem to operate in Modem Device Mode.

Is Your ISP Configuration for a Static IP Address?

More and more, ISPs are dynamically assigning configuration information. However, if your ISP

does not dynamically assign configuration information but instead gave you a fixed configuration,

your ISP should have given you the following basic information for your account:

•

An IP address and subnet mask

•

A gateway IP address, which is the address of the ISP’s router

•

One or more domain name server (DNS) IP addresses

•

Host name and domain suffix

For example, your account’s full server names may look like this:

mail.xxx.yyy.com

In this example, the domain suffix is

xxx.yyy.com

.

Preparing Your Computer

If an ISP technician configured your computer during the installation of the service for a static IP

address, or if you configured it for a static IP address using instructions provided by your ISP, you

need to be sure you have that configuration information recorded. You will need to configure your

computer’s TCP/IP settings to use a static IP address, , then connect to the modem to configure it.

Once the modem is set to operate in Modem Device Mode, you will need to reconfigure your

computer with the TCP/IP configuration you recorded from your ISP.

Restarting the Computer

Once you’ve set up your computer to work with the modem, you must reset the devices to be able

to communicate correctly.

1.

Pull the modem’s power adapter out of the socket on the back, then put it back in to reset

it, and wait about 10 seconds.

2.

Restart the computer that is connected to the modem.

Ready for Configuration

After configuring your computer for TCP/IP networking and connecting it to the DM602 modem,

you are ready to access and configure the modem. Proceed to the next chapter.

Chapter 4

Basic Configuration of the Modem

This chapter describes how to perform the basic configuration of your Model DM602 ADSL

Modem

for your Internet connection.

Accessing the Web Configuration Manager in the Modem

In order to use the browser-based Web Configuration Manager built into the modem, your

computer must have a web browser program installed such as Microsoft Internet Explorer or

Netscape Navigator. Because the Configuration Manager uses Java, your Web browser must be

Java-enabled and support HTTP uploads. NETGEAR recommends using Microsoft Internet

Explorer 4.0 or Netscape Navigator 4.0 or above. Free browser programs are readily available for

Windows, Macintosh, or UNIX/Linux.

To configure the modem for Internet access using your browser:

1.

Turn on the modem and wait at least ten seconds for initialization to complete.

If you normally use a login program such as Enternet or WinPOET to access the Internet, do

not launch that program.

2.

Configure your computer with the static IP address of 192.168.0.2, and a subnet mask of

255.255.255.0. If you need assistance with this, please refer to “Preparing Your Computer for

TCP/IP Networking“ on page 3-1.

3.

Launch your web browser, and click your browser’s Stop button.In the Address or Location

box of your browser, type

and press ENTER.
