____ Enter the IP address, Subnet mask and Default gateway and also the DNS server addresses then click OK.

____ If there is no Network Connection, check the cable between the computer and router, modem/router or network switch.

____ Click the Change Adapter Settings.

____ Check the networking icon.

____ If you see the little yellow triangle with black exclamation mark, then you will need to log in to your router or modem/router to check its internet connection settings.

____ Click OK on the Local Area Connection Properties window to close it.

____ Right-click on the networking icon and select Open Network and Sharing Centre.

____ Try your web browser and see if you can load a webpage.

NETWORK CABLINGProcess of creating cable that will be used in creating a network between

computers, routers, switches and storage area networks.

COAXIAL— is consists of a core of copper wire

surrounded by insulation, a braided metal shielding, and an outer cover.

— is the kind of copper cable used by cable TV companies between the community antenna

and user homes and businesses.

TWISTED PAIRShielded and Unshielded

— STP. Uses a woven copper-braid jacket that is more protective and of a higher quality than the jacket used by UTP. It also uses a foil wrap around each of the wire


— UTP. Most commonly used incomputer networking.

FIBER OPTIC— the medium of choice for any installation that

is sending high volumes of data. — is a relatively safe way to send data because,

unlike copper-based cables that carry data in the form of electronic signals, no electrical

impulses are carried over the fiber-optic cable.

Unshielded Twisted Pair (UTP) Cable. Most commonly used type of cable in local area connection.

RJ45 Connector. An eight wire connector used to connect the computers to Category 5 (CAT5) UTP cables in a network.

Wire Stripper. Used to remove the outer jacket of the wire.

Crimping Tool. Used to conjoin the UTP cable to RJ45 connector to hold each other.

Cable (LAN) Tester. Used to test if the cable is properly done and can control the network.

1. Get the needed length of the cable and add a little extra wire, just in case.

2. Carefully remove the outer jacket of the cable. Make sure not to cut the wires inside. One good way to do this is to cut lengthwise with snips or a knife along the side of the cable, away from yourself, about an inch toward the open end.

3. Check the wires for any cuts that can expose the copper wire inside. If it has any, you will need to cut the entire wires off and start over at step one. Because exposed copper wire will lead to poor performance of connectivity.

4. Untwist the pairs and lay it flat. The white piece of thread can be cut off even with the jacket and disposed. For easier handling, cut the wires so that they are 3/4" (19 mm) long from the base of the jacket and even in length.

5. Arrange the wires based on the wiring specifications you are following.

Make sure that the color arrangement is in correct order.

7. Press all the wires flat and parallel between your thumb and forefinger. Cut the top of the wires even with one another so that they are 1/2" long from the base of the jacket leaving a 1/2" of room for the individual cables. Ensure that the cut wires are even and clean.

8. Keep the wires flat and in order as you push them into the RJ-45 plug with the flat surface of the plug on top. You can tell if all the wires made it into the jack if the wire is located in each hole. You may have to use a little effort to push the pairs firmly into the plug. Verify that the sequence is still correct before crimping.

9. Place the wired plug into the crimping tool. Give the handle a firm squeeze. Once you have completed the crimp, the handle will reset to the open position. To ensure all pins are set, some prefer to double-crimp by repeating this step.

10. Repeat all the steps with the other end of the cable.

11. Test the cable to ensure that it will function in the field. Miswired connection could lead to physical damage of computers or phone system equipment. A simple cable tester can quickly verify that information for you.
