Why Have a Home network

Our need for technology in the modern world is increasing rapidly, and so is our need for internet connectivity.  The average household owner usually owns a smart TV, mobile phone and a computer.  All of which require a connection to the internet.  The modern way of connecting such devices is to use wireless.  However, wireless connections can be very unreliable.  This article provides tells you the benefits of a wired home network, and how to set one up.

Wired Home Network parts list


This is the central device of a home network.  One of the ports on your routers connect you to the internet via your phone line.  The other ports on the router are for Local Area Network (LAN).  For example, if you router has 3 LAN ports it means you can connect to 3 devices via an Ethernet wire directly.  This is the most simple wired home network setup.

What if you have more than 3 devices, or want Ethernet sockets in each room? in that case you need to read what a network hub does.

Network Hub

A network hub is also known as a switch, it is a common connection point for devices in a network.  For example if you have 20 Ethernet sockets in your house, all the wires leading to these sockets come from a hub.  Network hubs come in a variety of sizes such as 4 port or 20 port hubs.  Its similar to the LAN ports on a router but on a much larger scale.

Ethernet Cable

An Ethernet cable is the standard used for network connections.  It is what connects an Ethernet socket in a house to the hub.  Ethernet cables are rated by its category, here are the most common Ethernet cables below:

CAT 5:  Performance up to 100 MHz, or 100Mb/s

CAT 5e:  Performance up to 100 MHz, or 1Gb/s

CAT 6:  Performance up to 250 MHz, or 10Gb/s

Ethernet Wall Sockets

Ethernet wall sockets look similar to telephone sockets.  It is important to buy the right category of wall socket to match your Ethernet cable, such as CAT 5e or CAT 6.

Wired vs Wireless Networks

Advantages of Wireless

  • Enable multiple devices to use the same internet connection using wireless.
  • Very easy to set up.
  • Sometimes the internet signal reaches into your garden. Which means you can browse the internet whilst sun bathing.
  • Freedom of movement

Disadvantages of Wireless

  • File transfer speeds slower than wired connection.
  • Connection can drop out suddenly.  Most the time you may not know why.
  • Wireless signal can be weak if its needs to travel through objects such as walls.

Advantages of a Wired Home Network

  • Because the connection is wired, there will be no wireless drop outs. Typically wireless drop outs are caused by interference from neighboring wireless routers.
  • A wired connection is more secure than wireless ones. This is because wireless networks are open to attack from hackers.

Disadvantages of a Wired Home Network

  • Can cost a lot of money to set up the infrastructure.
  • Wired networks are only good for devices that can plug in directly. Therefore it would not work on mobile phones.
  • Limited range of movement as a cable is needed

What Can be Connected Via a Wired Network

  • Smart TV.
  • Games console.
  • Cable or satellite TV.
  • Wireless booster boxes.
  • Ethernet convertors. Such as Ethernet to HDMI.

Design Your Wired Network

In order to design your network, you must be able to answer the questions below.

What Rooms Require Ethernet sockets?

The most common rooms for wired Ethernet sockets are living rooms and bedrooms.  Living rooms usually have many devices that need internet connectivity such as smart TV’s, games consoles. amplifiers and cable/satellite TV boxes.  Bedrooms usually have smart TV’s, printers and games consoles.

How many sockets in each room?

The number of sockets will depend how many devices per room you have.  Try to consider how many sockets you may need in the future too. 

The location of  sockets in each room

Ideally your devices within a room should be in a common location, so that all your Ethernet ports can be grouped together. The example below shows Ethernet sockets in a living room.  A total of 8 ports have been installed behind an AV cabinet.

Where will your Router and Network Switching hub be located?

All your Ethernet wires from your posts need to meet at a common location within your house.  Common places are within cupboards, lofts are under stair ways.  This will be the location of your main switching hub which connect all your sockets together.  Ideally your router should be located next to the switching hub.  The example below shows a network hub within a loft.  There is a total of 20 people CAT 6 Ethernet cables connected into the switching hub.  The telephone master socket and router is located here too.
