If you’re planning on adding a new Ethernet jack to one of the walls in your home, you can save a few bucks by doing it yourself. Installing a network jack is surprisingly easy, and only takes a matter of minutes with the right tools and know-how. Start by identifying a good spot for your jack, taking into consideration the location of your networking hardware and the layout of the rest of the room. Then, trace and cut out a hole for the wall plate that you’ll use to mount the jack itself. After that, it will just be a matter of running the Ethernet cable between the outlet and your modem and wiring the cable to a special connector designed to fit inside the jack.

How to Install an Ethernet Outlet

Trace the outlet's mounting bracket on your wall, and cut the drywall out with a utility knife. Run an Ethernet cable through your wall from your Internet equipment to the new jack. Thread the wires into a keystone connector and attach it to the jack's wall plate.

Creating an Outlet

  1. Scan the room for an open spot down low on the wall, preferably near an electrical outlet. Use an electronic stud finder to determine the exact location of the stud closest to the outlet. You can either put your Ethernet jack on the opposite side of this stud or on either side of the next stud in the row. [1]
    • Ideally, the location you select should be free from surrounding obstructions and provide a clear path to run your Ethernet cable later on.
    • Most Internet installers recommend setting up a new network jack a few inches from an existing outlet to establish a sense of symmetry and limit the number of potentially-unattractive wiring fixtures on other parts of the wall. [2]

    Tip: When determining the best location for your jack, consider where the network hardware furnished by your internet service provider is stationed in your home. You’ll want to situate your jack as close to this spot as possible in order to simplify the process of running and connecting your Ethernet cable.

  2. 2
    Mark the spot on the wall where you want to place the jack. Use a pencil to draw a small ‘X’ where the jack will go. Don’t obsess over the placement too much—you’ll be able to make any necessary adjustments when marking the exact location of the mounting bracket.
    • Make your mark dark enough to be plainly visible so you won't have to hunt for it while you're doing other things.

  3. Once you’ve got the bracket situated right where you want it, run the tip of your pencil along the inner edge of the wall plate mounting bracket for your network jack. When you’re done, you’ll have a rough outline that you can use as a template for cutting the hole for the wall plate. [3]
    • Line the wall mounting bracket up as evenly as you can with the nearby electrical outlet.
    • If desired, use a bubble level to ensure that the top and bottom edges of your outline are perfectly parallel with the floor.
  4. Head to the main circuit breaker panel or electrical control box for your building and flip the switch corresponding to the outlet you’ve chosen to install your network jack next to. Doing so will minimize your risk of electrical shock, as you’ll be working close by. [4]
    • Individual circuits should be plainly labelled on your breaker panel.
    • If you’re attempting to install an Ethernet jack somewhere other than your own home, you may need some assistance finding the right breaker.
    • If for some reason your breakers aren’t labelled, or they’ve been labelled incorrectly by mistake, an electronic circuit breaker finder can help you figure out which breaker to flip. [5]
  5. Score the outline lightly to make sure your lines are neat and precise. Then, go back over each line multiple times, applying more pressure each time. After a few passes, the excess drywall will simply pop out and you’ll be left with a nice clean hole for your Ethernet jack’s wall plate. [6]
    • You can also cut out the outline for your wall plate using a drywall saw, if you prefer. [7]
    • Be careful not to make the hole too big. If you cut it too small, you can always go back and enlarge it, but if it ends up being larger than the mounting bracket for the wall plate, you’ll be out of luck.

Running Cable to the Jack

  1. 1
    Drill a hole in the floor or ceiling behind your jack outlet if necessary. Depending on where your Internet equipment is located, you may need to run your Ethernet cable either up or down a level to its termination point. Fit a power drill with a 1 ⁄ 2  in (1.3 cm) drill bit and bore a hole directly above or below the outlet opening you just cut behind the wall. This will make it possible to route the cable from your networking hardware to the new jack. [8]
    • In most cases, the hardware setup that provides wired access to the Internet will be found in the attic, basement, or crawl space beneath your home.
  2. If you’ve drilled through the floor to reach your Internet equipment, feed the cable through the outlet opening and down into the lower level. If you’ve drilled up through the ceiling, it will make more sense to start at your networking center and guide the cable down a level to the location of the jack. In other words, always work from top to bottom. [9]
    • Avoid running the cable too close to electrical lines, water pipes, or other fixtures hidden behind your walls or beneath your floor. If for some reason you have no choice but to cross an electrical line, do it perpendicularly at a single point to reduce potential electrical interference.

    Tip: If you’re planning on hooking more than one Ethernet cable up to your network jack, wrap a strip of tape around the ends of the cables to keep them together as you snake them through the wall. [10]

  3. After threading the slack end of your Ethernet cable through the middle, insert the rectangular plastic bracket into the opening you cut out earlier. Fasten the bracket by drilling the included installation screws directly into the drywall through the molded holes at the top and bottom corners. [11]
    • Avoid overtightening the installation screws, as this could cause visible cracks in the drywall around the finished wall plate.
  4. Use a pair of wire cutters to snip off the excess cabling. Aim for a clean, 90-degree cut straight across the cable’s width, and be sure to leave around 1 ⁄ 2 –1 ft (15–30 cm) of cabling hanging out of the outlet to ensure a comfortable fit and prevent unnecessary pull. [12]
    • If you cut the cable too short, the resulting tension could damage the internal wiring or cause the entire cable to pull loose of the jack over time.

Wiring Your Ethernet Cable

  1. Place the cable inside a wire stripper in the appropriate notch for its gauge size. [13] Squeeze the handles of the tool to clamp the jaws down around the cable and cut through the sheathing, then slide off the loose sheathing while holding the cable steady. [14]
    • You should be able to find the exact gauge of your Ethernet cable listed somewhere on the package.
    • If you don’t have a cable stripper, you can also slice through the cable covering using a utility knife or pair of scissors. Just be careful not to sever or otherwise damage any of the wires themselves. [15]
  2. Most Ethernet cables contain 4 pairs of similarly colored wires. Untwist each pair to separate the individual wires, then fan them out to bring them closer to their respective slots. Align each wire with its corresponding slot and slip it down inside. [16]
    • Keep in mind that you’ll need to do this for the end of the cable leading to your modem, as well.
    • If you want to make things a lot easier on yourself, pick up a pre-connectorized Ethernet cable. This type of cable already comes fitted with the keystone connector ends designed to fit into your new jack, making it possible to simply plug-and-play. [17]

    Tip: There are two standard configurations for wiring Ethernet cables: T568A and T568B. The layout of the wires is a little different in each of the two standards, but you can use either one as long as your wire both ends of the cable using the same standard. [18]

  3. Align the pointed end of the tool with the top of the first slot and push straight down. As you do, the forked prongs will seat the wire snugly at the bottom of the slot, which will in turn slice through sheathing to enable conductivity. Repeat this action for each of the 7 remaining wires. [19]
    • Many newer punch-down tools also clip the excess wire at the edge of each slot automatically. If yours doesn’t, just grab your wire cutters and trim them as close to the connector as possible.
    • It may help to use a punch-down puck to brace the keystone connector as you work. A punch-down puck is a type of stabilizer base that holds small connector heads in place during crimping.
  4. If your keystone connector came with protective cover plates, snap them into place on the top or bottom of the connector head. Then, insert the connector into the wall plate on the side facing the interior of the wall. You’ll hear a click letting you know that the connection is secure. [20]
    • Be sure to buy a cover designed specifically for a keystone connectors. Otherwise, your cable won’t fit.
    • If you like, you can use a cable tester to confirm that your Ethernet cable and keystone connector are wired properly before moving on. That way, you won’t have to disassemble the outlet later on if you experience connectivity issues. [21]
  5. 5
    Fasten the wall plate over the jack mounting bracket to complete installation. Slip the included installation screws into the holes at the top and bottom of the wall plate. Use a power drill or screwdriver to tighten them inside the corresponding holes in the mounting bracket. Give the wall plate a quick jostle to make sure it’s secure, then connect to your computer or router to get online. [22]
    • Don’t forget to vacuum up any loose drywall or other debris that’s found its way onto the floor in front of the outlet.

    Do I strip the small wires before connecting to the jack?
    Community Answer
    No, neither for patch cable nor for installation cable. Don't strip small wires. Just strip the whole cable as needed for the type of the socket or connector you're going to mount.

  • Question
    Is it possible to do this without cutting open the wire? Couldn't I just run a standard ethernet cable through the walls and into my PC?
    Community Answer
    Yes, and to finish the wall nicely, use a "flexible opening cable wall plate", a "brush plate", or a "recessed cable plate".
