Go to an electrical store, Home center or Computer store and buy UTP (Unshilded Twisted Pair) cable. The cable needs to be at least cat 5, cat 5e,cat 6, or higher; you’ll also need to buy some RJ-45 connectors.

Another tool that you will need is RJ-45 Crimper; you will have to use it later to crimp the cable.

It is of great importance to understand the pinout positions of the RJ-45 connector. Ethernet cable consists of four pairs of twisted wires. Each pair needs to be connected to the proper order for the network connection to work. If you want to make a normal cable, both ends should be connected in the same order. There are many standards for ethernet wiring, but they are generally the same. Make sure you use the same standard for each end of the cable and everything will be fine. Most used standards are EIA/TIA 568A and EIA/TIA 568B.

This is a coloring diagram of these standards:

If connect a computer to router, a hub, a switch or another equipment, you should use a 568B standard on each end of a straight-through 10/100 BaseT cable; connect hub to hub or switch to switch you need to make a crossover cable.

Get the wire cutters and cut the sheath off of the cable about an inch or so from the end of the wires. Be careful not to nick the wires in the process. You don’t need to strip any of the wires, just spread the wires apart, untwist them down to the sheath and put them in the order they’ll go in the connector.

Straighten each of the wires and pull them together so they can be flat and in the right order.

Grab the cutters, line them up along your prepared wires about 1/2 inch above the jacket and cut the wires.

Insert them into the RJ-45 connector and make sure each wire is fully inserted to the front of the RJ45 plug in the correct order.

Put the wired plug into the crimper tool and crimp it. You should hear the clicking sound, but keep going until they stop clicking. When they do, release crimpers with your crimped jack.
