Category 5 UTP Cable with Male RJ-45 Plug at Each End
Note
: Flat “silver satin” telephone cable may have the same RJ-45 plug. However, using telephone
cable results in excessive collisions, causing the attached port to be partitioned or disconnected
from the network.
Uplink Switches, Crossover Cables, and MDI/MDIX Switching
In the wiring table above, the concept of transmit and receive are from the perspective of the
computer, which is wired as Media Dependant Interface (MDI). In this wiring, the computer
transmits on pins 1 and 2. At the hub, the perspective is reversed, and the hub receives on pins 1
and 2. This wiring is referred to as Media Dependant Interface - Crossover (MDI-X).
When connecting a computer to a computer, or a hub port to another hub port, the transmit pair
must be exchanged with the receive pair. This exchange is done by one of two mechanisms. Most
hubs provide an Uplink switch which will exchange the pairs on one port, allowing that port to be
connected to another hub using a normal Ethernet cable. The second method is to use a crossover
cable, which is a special cable in which the transmit and receive pairs are exchanged at one of the
two cable connectors. Crossover cables are often unmarked as such, and must be identified by
comparing the two connectors. Since the cable connectors are clear plastic, it is easy to place them
side by side and view the order of the wire colors on each. On a straight-through cable, the color
order will be the same on both connectors. On a crossover cable, the orange and green pairs will be
exchanged from one connector to the other.

The WGR614 v6 router incorporates Auto Uplink
TM
technology (also called MDI/MDIX). Each
LOCAL Ethernet port will automatically sense whether the Ethernet cable plugged into the port
should have a normal connection (e.g. connecting to a computer) or an uplink connection (e.g.
connecting to a router, switch, or hub). That port will then configure itself to the correct
configuration. This feature also eliminates the need to worry about crossover cables, as Auto
Uplink
TM
will accommodate either type of cable to make the right connection.

Preparing Your Network

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 v6 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 v6 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 v6 includes a built-in Web Configuration Manager. To access the configuration
menus on the WGR614 v6, your must use a Java-enabled Web browser program which supports
HTTP uploads such as Microsoft Internet Explorer or Netscape Navigator. Use Internet Explorer
5.0 and above and Netscape Navigator 4.7 and 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 router. 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.

Preparing Your Network

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 v6 Resource CD (230-10091-02)
,
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 v6 Resource CD
(230-10091-02)
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.
