Creating a Wired Ethernet Network

Setting up a network using a router and 
optional hub or switch
If you are setting up a network for more than two computers and you will be 
connecting your network to a high-speed Broadband Internet connection (cable 
or DSL modem), we recommend the use of a router. A router lets you access 
the Internet connection from any network computer. The router can assign IP 
addresses to the computers on the network and can provide firewall protection 
for your network as well.
In addition to a router, you need a straight-through cable for each computer 
you want to connect to the network. If your router does not have built-in 
switching, or if you have more computers than your router has ports, you need 
a hub or switch and a straight-through cable to connect the hub or switch to 
the router.

To set up a network using a router and optional hub or switch:
1If you are using a hub or switch, plug one end of the power adapter into 
the AC connector on the hub or switch and the other end into a grounded, 
110V electrical outlet.
-OR-
If you are not using a hub, go to Step 2.
2Plug one end of the power adapter into the AC connector on the router 
and the other end into a grounded, 110V electrical outlet.
3If you are using a hub or switch, plug one end of a straight-through 
network cable into the uplink port on the hub or switch (identified by a 
label or a switch). Plug the other end of the cable into the uplink port on 
the router. If the router has only a single port, use the LAN port and set 
the switch on the back of the router to crossover (X).
4Turn on your computers.
5If you are using a hub or switch, plug one end of a straight-through 
network cable into any numbered port on the hub or switch (except the 
uplink port). Plug the other end of the cable into the network connector 
on the computer. As each computer is connected to the hub or switch, the 
corresponding green indicator should light on the front of the hub or 
switch, indicating a good connection.
-OR-
If you are not using a hub or switch, plug one end of a straight-through 
network cable into any numbered port on the router (except the WAN 
port). The WAN port is used to connect the router to the DSL or cable 
modem, and is identified by a label or a switch. Plug the other end of the 
cable into the network connector on the computer. As each computer is 
connected to the router, the corresponding green indicator should light 
on the front of the router, indicating a good connection.
6Repeat Step 5 for each computer on the network.
7For an Internet connection, plug a straight-through cable into the WAN 
port on the router and the other end into the Ethernet jack on the DSL 
or cable modem.

Configuring
Windows for a
Wired Network
This chapter describes how to configure Windows XP or 
Windows 2000 for a wired Ethernet network. Read this 
chapter to learn about:
■“Naming the computers and the workgroup” on 
page 30
■“Configuring the TCP/IP protocol” on page 40
■“Configuring your router” on page 47

Naming the computers and the 
workgroup
Each computer on your network must have a unique name and be identified 
as part of a workgroup. This must be done individually on each computer.
To name your computers in Windows XP, go to “Naming the computers and 
the workgroup in Windows XP” on page 30.
To name your computers in Windows 2000, go to “Naming the computers and 
the workgroup in Windows 2000” on page 38.
Naming the computers and the workgroup in 
Windows XP
Use the Windows XP Network Setup Wizard to name each computer and 
workgroup as well as select other network settings in Windows XP.
ImportantThe network setup procedure uses the Windows XP 
Network Setup Wizard. The example screens show those 
screens that typically appear in the course of using the 
wizard. If your network situation differs from that used in 
this example, you may encounter additional screens or 
screens with different selections. Make sure that you read 
each screen in the wizard and make your selections based 
on your particular network situation.

4Click Next. The Select a connection method screen opens.
ImportantIf The wizard found disconnected network hardware 
screen opens instead of the Select a connection method 
screen, make sure that one end of the Ethernet cable is 
connected to your computer and the other end is 
connected to a router, switch, hub, or computer that is 
turned on, then click Next.
The wizard found disconnected network hardware screen 
will open if your computer also has wireless Ethernet 
networking built-in. If your computer has wireless Ethernet 
networking built-in, and your computer is connected to a 
router, switch, hub, or computer that is turned on, click 
Ignore disconnected network hardware, then click Next.

the Internet through a router (as in the example in “Setting up a network 
using a router and optional hub or switch” on page 25), click 
This computer 
connects to the Internet through another computer on my network or through a 
residential gateway
