Preparing Your Computer

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 DM602 modem is shipped preconfigured as a DHCP server. The modem assigns the

following TCP/IP configuration information for one computer only automatically when your

computer is rebooted:

•

Computer IP addresses—192.168.0.2

•

Subnet mask—255.255.255.0

•

Gateway address (the modem)—192.168.0.1

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

As part of the PC preparation process, if TCP/IP is not already installed, you need to manually

install and configure TCP/IP on your computer. Before starting, locate your Windows CD; you

may need to insert it during the TCP/IP installation process.

Install or Verify 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, which displays a list of installed components:

Enabling DHCP to Automatically Configure TCP/IP Settings

After the TCP/IP protocol components are installed, the PC must be assigned specific information

about itself and resources that are available on its network. The simplest way to configure this

information is to allow the computer to obtain the information from the internal DHCP server of

the DM602 modem. To use DHCP with the recommended default addresses, follow these steps:

1.

Connect the PC to the modem, then restart the modem.

2.

On the PC, open the Network control panel (refer to the previous section) and select the

Configuration tab.

3.

From the components list, select TCP/IP->(your Ethernet adapter) and click Properties.

4.

In the IP Address tab, select “Obtain an IP address automatically”.

5.

Select the Gateway tab.

6.

If any gateways are shown, remove them.

7.

Click OK.

8.

Restart the PC.

Selecting Windows’ Internet Access Method

To select Windows’ LAN Internet access method, follow these steps:

1.

On the Windows taskbar, click the Start button, point to Settings, and then click Control Panel.

2.

Double-click the Internet Options icon.

3.

Select “I want to set up my Internet connection manually” or “I want to connect through a

Local Area Network” and click Next.

4.

Select “I want to connect through a Local Area Network” and click Next.

5.

Uncheck all boxes in the LAN Internet Configuration screen and click Next.

6.

Proceed to the end of the Wizard.

Verifying TCP/IP Properties (Windows)

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

utility

winipcfg.exe

:

1.

On the Windows taskbar, click the Start button, and then click Run.

2.

Type

winipcfg

, and then click OK.

The IP Configuration window opens, which lists (among other things), your IP address, subnet

mask, and default gateway.

3.

From the drop-down box, select your Ethernet adapter.

The window 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

Configuring Windows NT or 2000 for TCP/IP Networking

As part of the PC preparation process, you need to assure TCP/IP is installed and configured on the

PC. Before starting, locate your Windows CD which you may need to insert during the TCP/IP

installation process.

Install or Verify 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 and Dialup Connections icon.

3.

If an Ethernet adapter is present in your PC, you should see an entry for Local Area

Connection. Double-click that entry.

4.

Select Properties.

5.

Verify that ‘Client for Microsoft Networks’ and ‘Internet Protocol (TCP/IP)’ are present. If

not, select Install and add them.

6.

Select ‘Internet Protocol (TCP/IP)’, click Properties, and verify that “Obtain an IP address

automatically is selected.
