Today practically every residence and tiny office has a local network, and an web connection.

You are watching: To create a computer network, you must have at least two computers.

The home network or small area network enables multiple devices e.g. PCs,tablets and so on to connect to every other, and also to attach to the internet.

In this tutorial you will learn just how you to build and also setup a home or tiny area network and also connect it to the Internet.

Choosing a Wired or Wireless Network

Do You construct a wired or Wireless Network? i beg your pardon is best?

Early (pre 2008) residence networks to be predominately wired networks.

Wired networks use Ethernet end UTP cable and also tend come be quicker than wireless networks, which is critical consideration if you are a gamer. The simple wired home network diagram listed below shows a minimum setup v a switch and broadband router.


Wired Network AdvantagesFast generally 100 Mbps come 10 GbpsSecure and also reliable.Wired Network Dis-AdvantagesDoesn’t job-related with devices that don’t have an Ethernet port e.g. Tablets and smart phones.Not so simple for visitors and mobile gadgets (laptops) to affix to.Main Uses

It Is finest used because that network backbone i.e. Connecting in between router,network switches and also wireless accessibility points on various levels (floors).

Home Wireless Networks

Wireless networks usage Wi-Fi. and are quick and easy to install, however are typically slower than wired networks. Check out Wi-Fi and Wireless networks for more details.

Wireless Network AdvantagesEasy come setup indigenous an end user perspective.Allows easy access to clever phones, Tablets and mobile devices.No cables to run.Wireless Network Dis-AdvantagesNot as Secure as wired networks without suitable configuration, and also easy come setup insecurely.Not as rapid as wired networks.Not as reputable as wired networks.Main Uses

Connecting peripheral tools like computers,smart phone,tablets etc.

Most home networks will usage a mixture of wired and also wireless.

Setting up a home Network -Components and also Structure

Today but most residence and small home office networks will usage a wireless network or combined network, as most human being use clever phones, and tablets which don’t have Ethernet support.

The main materials required to construct a common home/small office network are:

Router or Wireless router – associate the network come the Internet.Wireless access Point – used to affix Wi-Fi equipped gadgets to the network.Ethernet HUB or Switch -Used to affix Ethernet fitted devices.Cable cat 5, cat5e or cat 6 with RJ45 connectors.Telephone Cable v RJ 10 connectors.Broadband Filters.

The home network diagram below shows the structure of a typical little home network


For most residence networks the Wireless Router or Hub which connects the network to the web will be the main component that the house or little home office network, and also in many situations it will certainly be the only component.

The Wireless router generally incorporates a Wireless accessibility point,Ethernet switch, DSL modem and also Router in a solitary box.

This short video shows just how to use a Wireless house Hub ( BT) or router come create a residence network the is connected to the Internet.

Video Notes:

DSL Modem– switch digital signals into analogue signals that are perfect for sending out over a call line. That is usually constructed into the Internet/broadband router and is not usually purchased together a separate component.

DSL/Broadband Filter– used to filter out DSL signals from telephone signal so that you can access the internet and also use the telephone simultaneously. Often had as component of the link socket.

Wireless Router Location

The Wireless router will need to affix to the call line, cable or fibre network accessibility point in your home.

Therefore most civilization locate the Wireless router near to the main telephone socket.

However you deserve to usually adjust the location by making use of telephone extension cables or much longer WAN cables.

Note: WAN cables usage the very same connectors (RJ45), and cables as Ethernet cables.

Because the Wireless Router provides the Wireless access point climate you should location it in a central location, if possible, to get the best wireless reception.

Testing her Wireless Signal

The easiest way of experimentation you signal stamin in various locations is to use the inSSIDer Wi-Fi checker which is an application that you can install on your Android tablet computer or phone.

The general idea is to location the Wireless router in its desired location and then move roughly the home with the inSSIDer Wi-Fi checker, and also check the signal strength, and then change the place if necessary.

Extending Your residence Network

You can prolong your house network by:

extending your Wi-Fi coverage through installing extr Wireless access Points or a an ext powerful access point.or girlfriend can extend the Wired network by running cables into other rooms

Home Router Setup

To provide the house router you accessibility it via a web browser, and also login utilizing a username and password.

Before you enable devices to attach to your house network you should make some simple changes come the default setup parameters of your router.

The two crucial one are the SSID offered to accessibility the Router and the router admin password as the default username/passwords room well known, and also published ~ above the Internet.

The gadgets then attach without requiring you to get in a password. See Wiki on WPS

Home Network IP Addresses

All of your tools will need an IP address.

This is provided automatically by a business called DHCP which, by default, is listed by the house router.

IP address detailed by the DHCP server are well-known as dynamic addresses, as they deserve to change. You can additionally assign addresses manually, and these are well-known as static addresses.

Static Addresses space not usually assigned yet are often compelled when making use of Port forwarding.

They deserve to be assigned top top the network setups of the device, however preferably top top the DHCP server using reserved addresses.

Additionally the addresses used on your residence network are well-known as internal addresses.

When you attach to the web your maker will usage an external IP address. This address is the IP address of the router/hub. See internal vs outside IP addresses because that a much more detailed explanation.

Finding her DNS, IP, MAC Addresses and also Router IP Addess

You may need to uncover out what DNS servers you room using or the IP or MAC resolve of:

Your home Router.Your very own computer/tablet/phone

The main tool you use is the ipconfig (windows) or ifconfig (linux) tool.

The display screen shot listed below shows the ipconfig command use with the /all switch. I.e. ipconfig/all


Your home router is her gateway to the Internet. Once viewing your configuration some devices refer come it together the default router whereas other use the hatchet default gateway.

Checking Network and also Internet Speeds

On any kind of network the speed is minimal by the slowest component.

A computer system with a Gigabit network map talking to a computer system with a 100Mbit/s network card is restricted to 100Mbit/s.

Shared devices like switches and Wireless access points space network throttle points similar to traffic lights and roundabouts ~ above a road.

LAN speed test is a very useful tool for testing your regional network speeds. Check out understanding home network speeds.

For net speeds you deserve to use online speed test sites. View Understanding internet speeds and speed tests.

Home Network and also Internet connection Problems

You will certainly invariably have link problems indigenous time come time.
