Setting up a wired Ethernet network
We recommend using category 5, unshielded, twisted-pair cable (approximately 1/4” in 
diameter with a thin outer-jacket, containing eight color-coded wires), and equipment 
compatible with this type of cable. This type of cable is equipped with RJ-45 connectors 
(like a large telephone jack connector, but with eight pins) on each end.
Setting up a network using a router
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.
Help and 
SupportFor more information about configuring a wireless network, click 
Start, then click Help and Support.
Type the keyword wireless network in the Search box 
, then click the arrow.
ImportantCategory 5 cables are available in two different types; straight-through 
cables, used to connect computers to a router, and crossover cables, 
used to connect two computers.
To determine which type of cable you have, hold both ends of the 
cable with the connectors facing away from you and with the spring 
clip on the bottom. For straight-through cable, the wires on both 
connectors are attached to copper pins in the same order (same 
colors, left to right). For a crossover cable, the wires on each 
connector are attached to the copper pins in a different order (different 
colors, left to right). 
						

							109www.gateway.com
In addition to a router, you need a straight-through cable for each computer you want to 
connect to the network.
To set up a network using a router:
1Plug one end of the power adapter into the AC connector on the router and the other 
end into a grounded, 110V electrical outlet.
2Turn on your computers.
3Plug 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.
4Repeat Step 3 for each computer on the network.

5For 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 your router
After you have named your computers and set up TCP/IP on them, you can configure your 
router using your Web browser. For these instructions, we assume that you are using the 
router to connect your network to a high-speed Broadband Internet connection through 
an Internet service provider (ISP) and that you are configuring it as a DHCP server.
To configure the Linksys EtherFast Cable/DSL router:
1From one of the computers connected to the network, open your Web browser, type 
http://192.168.1.1 in the browser’s address box, then press ENTER.
2When prompted for a username and password, leave the username box empty and 
type 
admin in the password box, then click OK. The Setup page opens.
3Enter the following values in the appropriate fields:
■Router Name and Domain Name - Check with your ISP to see if entries are required 
in these fields and, if so, what entries are required. Normally, leaving the fields 
blank will work.
■LAN IP Address - We recommend that you accept the defaults.
■WAN IP Address - If your ISP assigns you a different IP address each time you log 
on, click 
Obtain an IP Address Automatically. If your ISP requires a fixed IP address, 
click 
Specify an IP Address, then type the values provided by your ISP.
4When you are finished entering information on the Setup page, click Apply.
5Click the DHCP tab on the top of the screen.
6Click the Enable checkbox, then click Apply.
7Press the reset button on your cable or DSL modem, then restart the computer. Your 
network should be running. Go to “Testing your network” on page 111.
ImportantThe following configuration information applies to the Linksys® 
EtherFast Cable/DSL routers. For any other brand or model of router, 
see the manufacturer’s documentation, which may accompany the 
router or be available from the manufacturer’s Web site.

Testing your network
Now that your home network is set up, log onto one of your computers and access a favorite 
Internet Web site.
If you are unable to connect to the Internet:
■Run the New Connection Wizard (see “Sharing an Internet connection” on page 112)
■Check all physical cable connections
■Compare the status lights on the front of the router or access point with the patterns 
described in the router or access point literature
■Temporarily turn off any firewall software on your desktop computer
■Turn off all of the devices, then power them back on
■Refer to your router’s or access point’s troubleshooting information
■Contact your Internet service provider

Sharing your resources
Sharing an Internet connection
Internet sharing lets all computers on the network access the Internet at the same time 
using one Internet service provider (ISP) connection.
To set up Internet Explorer on each computer on your Ethernet network:
1Make sure that the router or access point is turned on and configured as instructed 
by your cable or DSL provider.
2Click Start, right-click Internet, then click Internet Properties. The Internet Properties 
dialog box opens.
ImportantThe Internet setup procedure uses the Windows XP New Connection 
Wizard and Internet Explorer. The example screens show those 
screens that typically appear in the course of using the wizard. If your 
Internet connection 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 Internet connection situation.
If you use a browser other than Internet Explorer, see the help 
provided with that browser for configuring it for use on a network.
ImportantIf you are using a dial-up modem instead of a broadband connection, 
see the documentation that came with your router or access point 
for the correct procedure.
