Although wireless is very convenient, a cabled connection will typically be faster and more reliable than Wi-Fi. Here’s how to hardwire ethernet cable into areas where high-demand devices live so you make the most of your internet connection.

 

We’ll also show you how to work with a licensed installer to bring these cables back to one point in a cupboard or on a shelf that’s tidy and out of sight.

 

What is a cabled network?

 

A well-designed communication hubA well-designed communication hubA cabled local area network (LAN), also known as ethernet, uses cables to directly connect your devices to your modem-router and the internet.

 

A local network also enables your devices to talk to each other, and can improve speed when sharing files between computers or streaming music or video from a computer to other devices on the network.

 

Most network-capable computers and devices these days can transfer data via cable at speeds faster than a typical Wi-Fi connection and usually even faster than your internet connection – which can mean no more lag or freezing when streaming movies or television.

 

Such connections between devices are made with ethernet cables (rated at least Cat 5e, preferably Cat 6). The plugs are known as RJ45.

 

How do I create a cabled network?

 

First decide how many rooms or areas need a connection and how many devices you want to plug in at each location.

 

Let’s say that your modem-router is on a shelf some distance away from the areas that need connecting. You have a media room where you want to connect a smart TV, a media server (such as an Apple TV box), a soundbar that is the hub of a wireless sound system, and a games console. You also have a home office at the other end of the house where you need connections for two PCs and a networked printer, as well as a sitting room where you want a smart TV.

 

Getting familiar with the hardware you’ll need will help you understand how easily this can all be networked. Here are some key elements used in the project:

 

  • Ethernet or networking switch – these hub-like devices allow communication between multiple devices, not just to and from a single source. You can plug one into your modem-router to turn one socket or port into multiple connections, or you can have one at the receiving end of a single line (such as a media room) and connect multiple devices at that end. You can also plug one directly into your modem-router to feed a distribution wall plate. Home ethernet switches could have anything from five to 26 ports. When choosing them remember that one socket will be taken up by the main network connection, so a five-port switch will only let you connect four devices.

 

  • A two-aperture plate with RJ45 ethernet and TV aerial connectionsA two-aperture plate with RJ45 ethernet and TV aerial connectionsAn aperture grid (or gang plate) is a wall plate with holes for taking a range of inserts. These plates are the face covers used with matching mounting grids when making up your own multi-connection plates. For a location such as a media room you could customise a dual-aperture plate to carry ethernet and TV aerial. You can also use these plates to create a distribution panel for multi-room cabling.

 

  • Cat 6 RJ45 grid plate insert – the part that fits behind the aperture grid plate to give you an ethernet wall socket.

 

  • Cat 6 solid core ethernet cable – the (typically blue) wiring that connects your plate inserts in different locations.

 

  • IDC (Krone) or 110-type punch tool – used to wire ethernet cable into the grid plate inserts.

 

  • RJ45 crimping tool – used to make patch cables using RJ45 plugs and ethernet cable.

 

  • Network test tool – enables you to check the quality of ethernet sockets and leads and troubleshoot network wiring problems.

 

As with wiring for light and power, any cabling done inside walls (and creating wall plates) needs to be done by a data installation specialist. Apart from the risk of electric shock when running new cables, a specialist knows how to position data cables to avoid interference from electrical cables and other sources.

 

Our cable network installation

 

Here is how we created a cabled Use multi-aperture grid plates with ethernet inserts to create network distribution pointsUse multi-aperture grid plates with ethernet inserts to create network distribution pointsnetwork at our house:

 

  • A five-point ethernet switch was connected to the LAN port on the back of the modem-router.

 

  • A three-aperture grid plate with RJ45 sockets was added to the wall beside the modem-router.

 

  • The ethernet switch was connected by patch cables and a new cable was fed inside the wall to each room.

 

  • For the media room, an ethernet cable was run down the same route as the TV aerial line and the aerial wall socket was converted to a dual-output aerial and ethernet outlet. Another five-port ethernet switch was connected to the RJ45 wall socket and then devices were connected to the switch with patch cables.

 

  • For the home office, a single line was fed to a single-outlet ethernet wall socket, then a five-port ethernet hub was connected. Devices were then connected to the switch with patch cables.

 

  • For the lounge room, an ethernet cable was fed down the same route as the TV aerial line and the aerial wall socket was converted to a dual-output aerial and ethernet outlet. The TV was connected to the outlet with a patch cable.

 

Tips for your networking project

 

Here are some more handy tips for setting up your cabled network: 

 

  • Add vents to the top and bottom of cupboardsAdd vents to the top and bottom of cupboardsEnsure that you have enough power outlets where you plan to have your networking hub. Have an electrician install more if necessary.

 

  • Your equipment can generate a lot of heat so if it’s in a closed cupboard ensure there is good air circulation. Add vents at the top (or the side towards the top) and at the bottom. You’ll find snap-in vents are easiest and neatest to fit. Just jigsaw the correct-sized hole and their flanged edge provides a neat finish. Leave a 10mm space in front of or behind shelves. This allows for passive convection cooling airflow – hot air escapes at the top and sucks cooler air in through the bottom.

 

  • Allow space between pieces of equipment for air circulation and cooling.

 

  • Elevate your modem-router as much as possible to maximise your Wi-Fi range and signal strength. Aim to lift it above the height of things like fridges as they can be serious signal blockers.

 

  • If you need to run cables along skirting boards or benchtops, check out cable-management products such as D-Line 2m White Cable Management Quadrant Adhesive Covers that can conceal and protect cables and be painted to match the background.

 

  • Use colour-coded patch leads to reduce confusionUse colour-coded patch leads to reduce confusionAsk if your installer can use colour-coded cables to feed different areas of the house and then repeat this coding from the wall plate in that area. This reduces confusion and can help when troubleshooting any issues. If you have multiple devices connected to an ethernet switch, somewhere such as a media room or home office, use colour-coded patch leads to make setting-up and moving devices much simpler.

 

  • Having trouble getting some smart devices to connect or stay connected to your network via Wi-Fi? Many new modem-routers are dual-band wireless (2.4 & 5MHz) and have a feature called band steering that attempts to direct devices to what it assumes is the correct band. Many devices only use 2.4MHz and this re-steering can cause them to drop out or be slow to connect. Go into your modem-router's set-up page via your browser or smartphone app, locate "band steering" in “Wi-Fi” or “Advanced network > Wi-Fi settings” and turn it off. This way devices will automatically connect to their preferred band. If you don’t know how to access your modem’s settings via a web browser your ISP’s webpage will have simple instructions on how to do this.

Keep us updated on your project @Neo19 and make sure to take plenty of before and after shots. I'm looking for some inspiration to improve the rats nest of cabling at my house. 

 

Reach out if you need any assistance.

Just Starting Out

The term "hub" should not be used as the use of these devices (if you can find then) WILL create network congestion and slow down your network. They are akin to driving along a road, coming to a 4 way intersection where all roads are major roads and they all have a give way sign - all drivers have negotiate with all other drivers so there is no collision and when one driver gets through all that negation would have to start again. The thing with a hub is there is no negotiation.

 

You should always look for switches. These are "smart hubs" in that they learn where all the other devices are and will send the signal destined to the device it is meant for out the port that device is connected to instead of a hub which sends the signal out all ports (except the port it came in from) because it does not know which port what device is connected to.

Welcome to the Bunnings Workshop community @Clanman. It's wonderful to have you join us and many thanks for jumping into the discussion.

That's some great feedback which I'll pass on. As you've mentioned, hub devices have typically been largely replaced by switches and routers and would generally only be found in older installations.

 

We look forward to hearing all about your projects and plans around the home and garden and encourage you to reach out anytime you need assistance or have something to share.

Hi @Clanman , thanks for the feedback.
I used the term 'hub' in reference to ethernet or network switches as it is a term less tech-savvy users are likely familiar with from USB hubs so it will immediately provide a degree of recognition - turning one connection of one type into many of the one type.
Searching google for 'ethernet hub' in-fact takes you primarily to ethernet/networking switch results.
I'll have a chat with the Workshop editorial team & see if we can make it a little clearer.

Having an Impact

One of the things that I did as a part of our recent home renos was to relocate the "internet line" coming into the house from our son's bedroom into a more central location in the bottom of a living room cupboard, letting me run a few points out from here to behind TVs etc. and hide the modem, home server, printer, and other random tech bits-and-pieces away.

Nowhere near as neat and tidy as yours @Adam_W , and in desperate need of some custom length cables and zip ties (on the to-do list)!

The other major upgrade was to give the modems built-in WiFi the boot in lieu of a PoE (Power over Ethernet) powered WiFi Access Point smack bang in the middle if the house (hallway roof fit the bill nicely).  Not only does this help with the wireless range throughout but is also expandable and relatively easily upgradable / replaceable in the future as better wireless protocols become more mainstream.

Amassing an Audience

I used to be a big advocate for wiring the whole house in previous houses mainly because I'd grab a box or 2 of cat 5e or 6 from the back of the bosses truck (don't tell him), although this house some devices I have run as a LAN I have also found with majority of my house being on home automation the need for a very good Wifi network needed to be in place and that came in the form of a mesh Wifi system to cover the area and also handle the amount of devices and traffic. It also means less time fishing cables down walls and patching over noggins for internal walls.

 

Worth having a look at as an option.

Finding My Feet

Let's say the internet arrives via the NBN box situated in the garage. Let's say the ethernet switch is somewhere else in the house. Most rooms are wired into this switch.

 

Can I just run a cable from the NBN box through to the switch? Or does the switch need to be physically located right next to the NBN box?

Welcome to the Bunnings Workshop community @NeverTooOld. It's fantastic to have you join us, and many thanks for your question about setting up a cabled network.

 

When you say "NBN box", is this a box attached to the side of your house, or inside the garage? It sounds like you have an NTD box inside your garage. Typically, an NBN technician would run a coax cable from that box to a reasonable location within your home where the NBN modem would sit. From the modem, a cat cable is run to your router/ethernet switch.

 

You would need to speak with your ISP to determine whether a modem is needed for your setup, as it doesn't sound like you have one. Perhaps it's included in this box in the garage? What outputs does it have on it? If it's just got a coax cable, then that needs to be connected to your modem. I think your ISP should be able to guide you through the connection process.

 

Please let me know if you have any questions.

thanks @MitchellMc .  Our's is a new build so I am just planning ahead at this stage. No actual box installed yet.

 

As you suggest, I think it will be a NTD box inside the garage. What happens after that, I am not sure. Just trying to figure out the appropriate place to  bring all the cat6 cables together for the patch panel and switch.
