This wikiHow will show you how to create an ethernet cable at home.

  1.  Use your cable strippers at about 1-2 inches from the end of the cable to remove the outer jacket.
  2. This can be done just like a regular twist-tie on a loaf of bread, but with four of them of different colors.

  3. For this scenario, you'll be making a straight-through cable, which has both ends of the cable with the same alignment of wires, so it's easy enough to do. Since this is your first cable, we'll consult the cheat sheet to know what order we're aligning in!
  4. Once you've untwisted the wires, you'll have a superfluous amount of copper wiring left; we don't need this much, but it's good to have it in the previous step to help in aligning the colors properly. Use the wire-cutting scissors to cut these off.
  5. Be careful not to bend the wires while pushing them in or you run the risk of creating a bad cable. You also don't want too little or too much wire left in the head; there's no definite length necessary, but it's pretty obvious to tell if there's too much cable or not enough. A short length of the jacket should be up the RJ45 head; use this knowledge as a reference.
  6. (Consult your cheat sheet if needed!)
  7. If you don't crimp the cable all the way, the head may come off.
  8. If you're repairing one end, this won't apply to you, so move on.
  9. Plug one end of the cable into the tan, two-port end of the cable tester, and the other end into the other part of the tester with the graphic display window. Turn it on and listen for the beep. If it beeps once, you successfully made an Ethernet cable; if it beeps twice, some part of the cable is messed up and needs repairing. Depending on the error, the cable may or may not still be usable.
  10. Now that you've made an Ethernet cable all by yourself, you can connect all kinds of devices together! Of course, for the cable you just made, make sure they're different devices! You can connect to Xbox Live now, to Playstation Network, to your wireless router, and many more devices you don't even know about! Or, if you're known as the life of the party, you can show off to your friends and never have to worry about being invited to another party again... !

  • Question
    Can the same port be used for a 2.0 and 3.0 USB connector?
    Community Answer
    Community Answer
    Ethernet cables cannot run through USB ports. USB ports and Ethernet ports are completely different and have different functions.
  • Question
    Do longer Ethernet cables reduce connection speed?

    Yes, but not to the extent that you'll ever notice. Ethernet cables lose speed over massive distances. There will be no significant difference between a cable that travels the length of your house and one that's connected to a device right next to the router.

Tips

  • Many times, the error with making these cables comes from the wires not making it in the gold pins far enough, so it's important that they're all the way in.
  • Keep the RJ45 head with the protruding clip facing down relative to you. Also, if you accidentally bend the wires while pushing them into the head, you risk creating Electromagnetic Interference if the copper becomes exposed, which lowers the quality of the cable.
  • Use your thumbnail to determine how much wire to keep when you cut the extra off; remember to keep a death-grip on these wires to keep the alignment proper.

Warnings

  • There's a reason you need eye-protection: when cutting the copper wires, they can go flying and potentially get your eye! Be smart, be safe!
