` Depending on how elaborate they are, home networks can be complicated. Unfortunately,

because of this complexity, problems occasionally happen. Fortunately, you can usually solve

these problems yourself. In most cases, finding the problem is a matter of going through a

series of steps to eliminate potential issues one by one until you find the source of the problem.

This article walks you through isolating your problem, troubleshooting the problem, and, if

necessary, contacting the right organization for support.

` If you are setting up your home network for the first time, refer to Set up a wired network or Set

up a wireless network. The guidance in this article assumes that you were previously able to

use your network, although the information here might be useful for troubleshooting setup

problems, too.

` People who work with networks think of them in terms of layers. These layers include the

Internet, your modem and router, and the computer (or computers) on your network. To

troubleshoot a problem effectively, you must first identify which network layer is causing the

problem. The following diagram shows the different layers that might be the cause of a

problem.

` If Microsoft Windows indicates that your network adapter is unplugged, it could be because of

several different problems. Follow these steps to troubleshoot the problem. (You can stop

following the steps if your network connection starts to work.)

` Verify that both ends of the network cable are properly connected, as described in Set up a

wired network.

` If the cable is properly connected, verify that your modem and router are plugged in and

turned on.

` If you have more than one network port available in your switch, plug the cable into a different

port. If the network connection works, the original port on your Switch is faulty. However, you

can continue to use the other ports.

` Replace the network cable with a new cable. You might have a faulty network cable.

` The network adapter on your computer might have failed. If possible, connect a different

computer to the same network cable. If the connection works, the problem is with your network

adapter. Contact your computer manufacturer for support, orinstall a new network adapter. If

the new computer also fails to connect and you have already tried a new network cable, yournetwork hardware (the device you connect the network cable to) has failed. Contact technical

support for the network hardware, or replace it.

` After following these steps, you should have identified the problem as your computer's network

adapter, the network cable, or your network equipment, and then either replaced or repaired the

failed device.
