Setting up an 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.

Creating an Ethernet network
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.
In addition to a router, you need a straight-through cable for each computer you want to 
connect to the network.
Important Category 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).

Chapter 7: Networking Your Computer
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:
Important The 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.

Troubleshooting Your Ethernet network
Troubleshooting Your Ethernet network
You cannot see the other computers on your network
■Make sure that your Ethernet cable is plugged into the Ethernet jack on your 
computer. Make sure that the other end is plugged into a router.
■Make sure that all computers are plugged into a powered electrical outlet and 
turned on.
■Make sure that the router is plugged into a powered electrical outlet and turned 
on. Most routers have lights that indicate they are working. For more information, 
see the documentation that came with your router.
■Make sure that all computers on your network have the same workgroup name.
■Make sure that all computers are using the same Subnet Mask.
■If you assigned IP addresses to the computers, make sure that all computers have 
different IP addresses. For home networks, IP addresses should be 192.168.N.N 
where N is a number you assign between 0 and 254. The first N should be the 
same for all computers on your network and the second N should be different for 
all computers on your network.
The computer does not recognize an add-in Ethernet card
■Shut down and restart your computer.
■Make sure that you have installed the required software. For more information, 
see the documentation that came with your Ethernet card.
■Reseat the card. For more information, about opening your computer case, see 
“Opening the case” on page 51. For more information about your Ethernet card, 
see the documentation that came with your Ethernet card.
Your Ethernet network is running slower than you expect
■If your Ethernet network is running slower than you expect, check the speed of 
each Ethernet component. For best results, all Ethernet components should be 
standard Ethernet (10 Mbps), Fast Ethernet (100 Mbps or 10/100 Mbps), or Gigabit 
Ethernet (1000 Mbps or 10/100/1000 Mbps). A mixture of Ethernet, Fast Ethernet, 
and Gigabit Ethernet components will result in your network running at the 
slowest component speed.
