Wiring the house with Cat5e for Gigabit Ethernet

I’d been using wireless networking at home, and generally this worked fairly well. But a couple of things were problematic. Firstly it would occasionally go out for a few minutes at random (which I ascribed to the neighbor’s wireless phone). Secondly it was rather slow using Media Center Extender for the XBox 360. It seemed to work for streaming regular definition video, but anyhing higher was dodgy, and navigating menus of content (like photos) was painfully slow.

So I decided I’d upgrade from the podunk 54Mb/s to a stunning 1000Mb/s fully switched network.


This meant I had to install six wall sockets. One for the internet connection (in the kitchen, for some odd reason), one for the new switch (in a cupboard, out of the way), and four outlets (3 in the bedrooms, one in the living room for the Xbox. That means I have to lay five Cat5e cables, each one going from the switch to an outlet.
Having never done this before, I was a little uncertain how to go about it. Luckily many have gone before me.

Cutting the holes in the wall was not something I was looking forward to, as patching drywall always seems to go badly for me. I thought at first I’d have to cut large chunks out so I could install junction boxes to the studs. But I eventually figured I could just cut small holes in the wall (see pic), and then mount the faceplate with self-drilling drywall anchors. This worked out really well. Just pre-drill 1/4″ holes for the anchors to avoid crumbling the edges of the hole. It’s pretty solid.

Up in the attic there’s a whole mess of wires. It took me a while to find out the correct spots. I mostly went by existing wiring, and hence my network outlets ended up next to my cable outlets. I drilled 1/2″ holes in the header beams where needed. 1/2″ can take four Cat5e cables (so I needed 2 for the switch).

img_4409_400.jpgc184-03791.jpgIt took a few hours to get all the cable in place. Then it was simply a case of wiring the sockets. These use a standard “keystone”, which is all color coded, and very easy to wire (just double check it). The sockets come with a little plastic tool to set the wires. You don’t need any special tools, just remove an inch of the blue outer insulation (from the cable, not the wires). Then keep the wires as twisted as possible, and push them into the color coded connectors, and push them down with the tool. (Same color configuration at each end – the keystones have an ‘A’ and ‘B’ config, just use ‘A’ for everything).

I used a six outlet plate at the switch (five outlets, one cover plate). If you have more you’d use a patch panel, but this looks very neat. One problem was that the hole had to be larger, so the large anchors did not work very well. I used plain 1″ drywall screws, but you could possibly use smaller wall plugs (or actually stick a box in there). When everything was wired up, I hooked up patch cables to all the devices, and the gigabit switch, and turned it on. Everything worked first time. Woo hoo, 80 wires set in place without mistake.

Of course it’s not actually gigabit, since all the devices are actually 100Mb, but the 5-port gigaBIT switch (a D-Link DGS-2205) was only$30 or so. If I get some gigabit devices in the future, then all will be well. The cable runs were pretty short as well (like 25 feet max) so it could probably do 10Gb later.

Results? Well, the internet now no longer goes out. Media center is a lot faster – actually very usable now for browsing through photos. Everything went according to plan. Very odd.

Parts List:

Tools used

  • Drywall saw
  • Wire setting tool (comes with keystone sockets)
  • Drill with long 1/2″ bit for drilling through headers
  • Fish tape for pushing/pulling wire, especially through walls with insulation.
  • String (sometimes easier to push string through with the fishtape, then pull cable)
  • Screwdriver

Took about six hours of work.

    I’ve got to say… that’s a pretty impressive picture. Reminds me of that scene in the Matrix where NEO is connected to all those tubes.

    I did my home network cabling this way and I spent about 200 ft of cable. I prefer wired connection instead of wireless because on my point of view it is more stable.
    I enjoyed doing this work.

    Nice informative post Mick.

    Jack I’ve found that there is a good place for both wired and wireless in the home. My wife and I have six kids and a lot of Internet gamers in the house. They need the wired connections for gaming as the latency with wireless can pose a problem. However, my wife and I love to sit out on the back deck with a glass of wine and our laptops and enjoy the wireless connectivity.

    Best regards to all,

    this is a great DIY project, and you’ve laid out the steps very nicely. Unlike you though, if I were to try this, all would not go well.

    Awesome job! Wished mine looked as good, but it’s more like a tangled mess of cables. I decided to go wireless for the upstairs because it would be so hard to run the cable through the existing walls.

    I would like to make the switch to Gigabit in my home for the same reasons outlined in this article but have a quick question.

    I already have a home network in my house and all of the cable is punched down with 4 twisted pair (8 total). Does that mean I already have CAT5e that is capable of Gigabit?

    If so, then all I have to do is purchase a few Gigabit switches, but wanted to ask before I spent the money.

    Cat5e is a specific type of cable with 4 twisted pairs, there is also Cat5 (without the e). And Cat4 and Cat3. The type of cable is usually printed on the cable sleeve.

    It’s probably that you have at least Cat5, which should give you fine gigabit performance on the short runs inside a home. You can in theory even use Cat4/3 for gigabit ethernet, depending on the length of the cable and sources of interference.

    ok dumb question …the internet connection you mention in your article comes from the router, yes? So if I run my cables to distant parts of the house and then put a wireless access point like an apple airport I could have wireless there…

    @Mick – AirPort Express’s are great access points and can be used exactly like you suggest (‘bridge mode’). If you have several all with the same SSID and passphrase, your PCs will automatically jump between them as you wander around :)

    Informative article for me thank you !
    My recommends is to check the connection between keystones with network tester to remove some problems after that :)

    Very informative post Mick and a great name you have too! I live in a brick house with reinforced concrete and so I have real problems with wireless. Also, I can’t run cables through the walls either and so have a mess of wires running around the edge of rooms!

    This is pretty impressive. I too am all about the wireless connections and the least amount of cables as possible. The ones I do have look like a birds nest, there may even be some real twigs amongst all the tangled wires!
