How to install a network jack into a wall from the attic.


After seeing the tour of my home network,
many viewers have requested a video explaining how to install a network jack into the wall. OK, so we’re standing in front of an unfinished
wall. And the reason I wanted you to see this is because there is no sheetrock on this side
so you’ll know exactly what you’re up against. Now, if you look up at the top, you’ll see
this is what’s called the top plate. And there’s going to be at least two 2×4’s up there and
sometimes there may be three. So you’ve got quite a bit you’ll have to drill through. It’s important to consider that in most cases
you will only be able to use an interior wall. In most cases the roof-line will prevent you
from being able to reach the top plate of the exterior wall, and even if you could,
the roofline would be in the way of the drill, and even if you could overcome that, the wall
will be filled with insulation so there’s no way to feed the wire down. You’ll need to go to the hardware store and
pickup one of these old-work boxes. You’ll also need a network jack and a plate. OK, because of the way this room is shaped,
and the living room is taller than the rest of the of the attic, you’ve got a small little
short wall here. But, once we remove that, you’ll see the top plate that I was talking
about. We’re going to have to drill through that. So the first thing you’ll need to do is verify
the cable you have is long enough to reach. You can approximate by running it on the ground
floor. You’ll need to use a stud-finder and mark the studs on the wall. I like to use
masking tape to mark where the studs are. Normally when people are searching for studs,
it is because you want to screw something into them. However, in this case we’re trying
to avoid them. If there are any nearby outlets of any kind go ahead and take off the plate
so you can meaure how far the box is from the floor. This way you can be sure your new
box lines up with the existing ones. I just use another piece of masking tape to help
me out. So to mark your place on the wall, turn the box around backwards and find the
little marker holes and make 4 little dots on the wall. Once you have your dots, you
can draw a square on the wall. Now take a razor blade and begin to cut a hole in the
wall. This is a learned skill that just takes some
practice. I usually just go over the same lines several times alternating the direction.
Eventually it will go all the way through the wall. Once you remove the piece of wall,
you should be able to sitck your hand in there and find the cable you dropped down the wall.
Now you can install your old-work wall box. The next step is to strip the insulation off
of the cat5 cable. Then seperate out the colored pairs and try to straighten them out to some
extent. Next you can use your fingers to align the colored wires onto the network jack. Once
you are sure they are all in the right place, use a punch tool to properly terminate these
wires. It should look like this when you are all done. Now you can mount the jack into
the wall plate and push any excess wire back into the wall. Once you mount the plate to
the wall, you are essentially done. One more thing about the exterior wall situation.
it is actually possible to do. When I first got an electric car it was necessary to run
a 240V wire to the charging dock from the breaker box. But the breaker box is on an
exterior wall. So I had to cut the sheetrock so that I could have access to run the wire
up into the attic. I’ve been too lazy to repaint the wall after doing this. So it is possible,
but not much fun. Well, I hope you liked the video. I would
just like to point out that the house I was showing in the video is not actually my house.
It’s actually a family member’s house. They bought a smart TV and wanted to be able to
connect it up to their home network so I decided to run a network jack for them. Now, I had
been planing to put this off probably until October. Because, Hey! we live in Texas. You
don’t want to get up into an attic in the middle of July in Texas. Fortunately, we had
this cold front come through this weekend. And I woke up Sunday morning and it was 68
degrees outside and raining. And so I decided this would be a good time to get up there
and do that network jack install. So you go to have this one a little bit early. Alright
well, tell me what you’d like to see in the next video. Until next time, see you later!

  1. Dude I need to do this currently I’m runnin a 35ft cable through my living room to my bedroom

  2. Great video!! Good explanation, I am just about to start installing my cables in the house, run it through my ceilings on the ground floor, and attic on first floor.. Going to be an great project, so looking forward to it. Just ordered the Firewall, Smart switch, AP for downstairs and soon (when payday hits) the AP for upstairs.. Going to document it all on my channel!

  3. You show CAT 5 wiring being used for telephone connections, I think this is rare. My house built in 1996 does not have CAT 5 wiring installed. I would think most viewers of this video do NOT have CAT 5 in their wall, making this whole video superfluous.

  4. Hey there. I also live in Texas myself any way I would like to ask you have you try do a video running  interior between though cells & floor why I ask I live in a 2-story home I would like to run a interior cable for TV & also a switch so I can used XBMC that they call it KODI box. For how I am used wireless cable TV streaming but I would like to run a hard wire so I can STOP used wifi extender okE-mail me Ok [email protected]

  5. For exterior walls, if you can't get through the insulation, you can always run the cable outside, just make sure you're using outdoor rated ethernet cables, and that you put sealant in the hole afterwards(silicone, for example). Also, never enter a cable in a hole in an exterior wall from the top, as the water from the rain will drip inside the hole – make a "U" with the cable if necessary, even if it's not looking very good. Or find a way to make it come from the bottom.

    You'll have to be a bit creative to find a way to make the cable the least visible possible. Following natural/existing lines on the wall is the key, you might also want to choose a cable color that matches the wall color as closely as possible (i.e., not using a blue cable if the exterior of your house is white, white cables will blend in more easily). If your house has vinyl housing, then it's your lucky day, you can unclip the bottom and hide the cables underneath. Otherwise, you might be able to find conduits that closely matches the color of your house and hide the cable in there. Oh, and if you have to drill into a brick wall, never drill into the brick itself, drill into the mortar (and use appropriate drill bit and hammer drill), otherwise, the brick might break under the pressure of the hammer drill and replacing that one brick can be quite an hassle – and that's if you can find an identical brick.

    Just a few tips from a telecommunication technician, as we constantly need to find ways to fish cables into people's existing home without tearing down walls. 🙂

  6. Great video, as always. I know I'm late to the party, but I will say that ( just like the step drill bit you were reluctant to try) a dry wall saw could make this whole process a bit easier and cleaner with less effort and time consumption.

  7. Not sure why you'd be running network cable from the attic. But, I can see doing something similar with coax for a TV antenna. I've done that before.

  8. I just want to thank you so much for making this video. So many other people skip steps or add extra nonsense. Thank you for a concise and informative video!

  9. I really love your videos. Thanks for sharing them. That is not masking tape at 1:56. That is painter's tape. The glue is weaker than masking tape.

  10. This video is useful…. but here in Mexico 97% of the houses are made with concrete and in square shape, most dont have second floors or an attic either. Still, nice video especially being this old

  11. IM FUCKING HIGH REEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE

  12. Is there a trade school in the East or southern Houston area where I can learn this trade? I being wanting to learn how to do this. I need hands on though. Houston, Dallas, or Tyler,TX?????

  13. I did the same with with a cable line. even in Cleveland attics get hot. I put a thermometer in it and it was over 100'F

  14. I have installed network jacks and coax jacks on a outer wall in the past, and yes it is had to drill the whole through the top 2×4 but not impossible. If you need to install these jack on outer walls you will need a right angle drill attachment and some times a 3 inch drill bit will work but most times you will need a 4 inch if the top 2×4's are doubled. Just wanted to share some knowledge!

  15. Very nice job on that, thanks for sharing! I was having wifi limitations, so I'm running ethernet cables 82 feet from where my MOFI gets the best reception to where my editing room is. Are there junction boxes that simply allow you to connect an already terminated ethernet cable to the back and you just plug in at the interior? ORrrrr.. do I have to get the wire, cut, and terminate on my own? I'd like to just plug it in on both sides of the box?

  16. if you drill a hole in the corner of the measured box and use a saw it is a bit easier, instead of the razor the whole time

  17. Guys, it's not "paper" walls, it's drywall, which is a form of plasterboard. Yes it is coated with paper, but it's made of gypsum. Only internal and internally-facing parts of exterior walls are finished with drywall. The exterior will be brick, stone, or siding (Wood, masonite or vinyl). https://en.wikipedia.org/wiki/Drywall

  18. I have two things to say even if this is an old video. 1. Do not untwist the wires. Your ethernett speed can reduse. 2. For those that do not have a way to get a cable behind the wall without thearing it down. Just know that you can get on wall mounted sockets as well.

  19. Very good overall. My only comment has to do with safety: (1) googles or other eye protection (you wear glasses, that's probably enough); (2) gloves – working with insulation, esp fiberglass batts; (3) dust mask/respirator (attics are incredibly dusty. I also wear kneepads for attic work (not a safety issue, but a comfort one); a long sleeve shirt would be helpful (even in TX in the summer). And finally, I throw all the clothes I have worn into the washing machine when I am done – by themselves.

  20. Why not get a dual wall plate with both RJ45 and RJ6 connections? You could even use a modular wall jack so you can run additional wires easily in the future.

  21. Shit I just ghetto style the set up by running long ass patch cables directly to the devices and use cheap brush plates to make it look “good enough” to avoid terminating wiring. Not a clean install but fuck all that work. Makes holes in the wall and run some cable, boom ! You got internet in the other room lol.

  22. it's interesting what these people call "wall" … 2.5cm of plasterboard …
    here you find that… like an "interior wall".. in modern buildings.. to be able to do these things
    but in traditional buildings you have solid bricks of 15cm joined by 3 or 4 cm of concrete…
    or in more new constructions… concrete blocks that are hollow inside … but guess what? … Yessss… they fill them with more concrete … to lock them each other
    so  to put a cable you have to make a channel with chisel and hammer all the way….
    and place there an electrical plastic pipe for run the cables inside ..
    then you cover all again with cement coating and paint…

  23. The utility knife he used had to be dull as hell because as coming from a family with construction workers you can put ur knife in there and just cut without any force, as long as u have a sharp or good blade

  24. My question is did you make a similar port near modem aswell? So plug modem cable into wall then at the other room you plug the new ethenet spot to computer?

  25. As an European sadly i can't cut my wall with a butter knife, the only solution is using Power Line. Anyway, are all american walls so thin and soft? What if you accidentally bump on the wall, don't you make a hole in it?

  26. My problem is I already have a cord with wires and another cord with a modular plug and I can't seem to fiqure it out for the wall mount Jack can someone help me out explain it

  27. This might sound like a dumb question but each color obviously has to make connections correct? Because my dog chewed up my cord outside that is connected to the inside and only the dark Orange the dark blue and the light blue were connected, the other colors were wrapped around the cord not connected… Like they were not being used for the Internet connection

  28. 3:25 "next you can use your fingers to connect the colored wires to the network jack"

    covers the most important part of video with hands and horrible camera angle

  29. Why not just use the existing low voltage hole that the Coax ran to? They make wall plates with multiple sections for keystone jacks.
