Appendix C
Preparing Your Network
This appendix describes how to prepare your network to connect to the Internet through the 54
Mbps Wireless Router WGR614 v5 and how to verify the readiness of 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 WGR614 v5 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. For an explanation of Ethernet
cabling, see
“Ethernet Cabling“ on page B-11
. 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 WGR614 v5 includes a built-in Web Configuration Manager. To access the configuration
menus on the WGR614 v5, your must use a Java-enabled Web browser program which supports
HTTP uploads such as Microsoft Internet Explorer or Netscape Navigator. Use Internet Explorer
or Netscape Navigator 4.0 or above.
Note:
If an ISP technician configured your computer during the installation of a
broadband modem, or if you configured it using instructions provided by your ISP, you
may need to copy the current configuration information for use in the configuration of
your firewall. Write down this information before reconfiguring your computers. Refer
to
“Obtaining ISP Configuration Information for Windows Computers
” on
page C-21
or
“Obtaining ISP Configuration Information for Macintosh Computers
” on
page C-22
for
further information.

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
NETGEAR 54 Mbps Wireless Router WGR614 v5 Resource CD (230-10091-01)
,
or in this appendix.
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 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 to provide it or you can try
one of the options below.
If you have a computer already connected using 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
NETGEAR 54 Mbps Wireless Router WGR614 v5 Resource CD
(230-10091-01)
for 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 haven’t 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
, 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.
ISP Host Name: _________________________
ISP Domain Name: _______________________
For Wireless Access:
See the configuration worksheet at
“Information to Gather Before Changing
Basic Wireless Settings“ on page 4-6
.
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 firewall must be assigned a 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. For a detailed explanation of the
meaning and purpose of these configuration items, refer to “
Appendix B, “Network, Routing,
Firewall, and Basics
.”
The WGR614 v5 router is shipped preconfigured as a DHCP server. The firewall assigns the
following TCP/IP configuration information automatically when the PCs are rebooted:
PC or workstation IP addresses—192.168.0.2 through 192.168.0.254
Subnet mask—255.255.255.0
Gateway address (the firewall)—192.168.0.1
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 PC preparation process, you need to manually install and configure TCP/IP on each
networked PC. 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.
