Wifi: the key benefits and the basics of how it works

The benefit of wifi is obvious: a wireless internet connection means our devices are not tied to a fixed location within a property. You see, wifi transmits a property's internet connection via special radio signals, allowing us to move around from one room to another, with no interruption to our internet connection.

This is obviously super handy for users of laptops, tablets and mobile devices. Once we're connected to wifi, access to the internet is suddenly so much more convenient and flexible.

Sunny day outside? Why not catch up on your emails whilst sipping a coffee in the garden — with wifi, you can!

The basics of wifi in summary:

  • Wifi is the wireless technology that all internet-enabled devices use to get online — without messing around with cables.
  • Home wifi internet is made possible via a wireless router, which is basically a box that transmits and receives wireless signals between an internet connection and internet-enabled devices.
  • To communicate with a router and connect to wifi, a device must have a wireless adaptor. Most internet-enabled devices today come with a wireless adaptor built in — but older computers may require a plug-in adaptor in order to get online wirelessly

General steps to connect to a wifi network near you

The following steps run through the general steps that anyone needs to take to get connected to the internet via wifi.

Step 1: Locate yourself in a property or public space that has a wireless router. I.e. Somewhere where a wifi signal is being transmitted.

Step 2: Make sure that the device you're going to use is a.) Capable of connecting to the internet and b.) Capable of connecting to wifi.

Step 3: Find out the name of the wifi network that the router in your location is transmitting. That's right, each wifi network has its own unique name. Sometimes this can be a sequence of random numbers and letters if it was set by default on the router — but people often personalise the name of a wifi network to help users identify its owners. E.g. "The Smith Family wifi" or "Fred's Cafe".

Step 4: Once you know the name of the wifi network, use your chosen device to find it. This will vary between devices (depending on whether you're using a Windows or Mac computer, or a mobile device). However, the process for connecting to wifi is broadly similar, following something along the lines of: navigate to wifi settings > turn wifi on > click on the name of your wifi network > click "connect".

Step 5: Many wifi networks are made private, with access restricted via a password. If your chosen wifi network is password protected, at this point it will ask you enter that password. Make sure you have the password at hand, and enter it.

You should now be connected to wifi!

An example of how to set up and connect to wifi at home (using a Windows 10 computer)

What you’ll need:
 
  • a wireless router
  • a Windows 10 computer with a built-in wireless adaptor or a separate adaptor.
Follow these step-by-step instructions to connect to wifi
 
Step 1: Set up your wireless router - an example of which is on the right - (see How to connect to the internet for instructions). Most internet providers now supply wireless routers as standard. When setting up one, it’s important to provide appropriate security so that your computer can’t be entered by anyone but you. Instructions for this should be supplied with the router, but if in doubt, consult an expert.

Step 2: Check that your computer has a built-in wireless adaptor. Up-to-date laptops generally have one, but most desktop computers don’t.
 
 
 
To check whether there’s a built-in adaptor you can search for 'Device manager' on your computer. Then find 'Display adaptors'.

 

 

If there is a wifi adaptor, a wifi icon should also appear in the system tray in the bottom right-hand corner of the screen. In Windows 10, 

 

If you don’t have a wireless adaptor, you’ll need to buy one to plug into one of your computer’s USB ports. The adaptor should be supplied complete with instructions on how to use it to connect to a wireless network.

 
For laptops select the Network icon on the system tray. The icon that appears depends on your current connection state. If you don’t see one of the network icons below or a similar one, select Up arrow icon to see if it appears there.

Step 3: To connect to a wireless network, click the wifi icon. You should now see a list of available networks 
 
 
 
Step 4: To connect to a network, just click on its name. If it’s a secure network and it’s the first time you’ve used it, you’ll need a password. If it’s your home network, your internet provider will have given you a password – sometimes it’s printed on a sticker attached to the router.
 
If you’ll be using the same connection regularly, you can tick the box to connect automatically.

Step 5: Once you establish a connecion, your Windows 10 PC will ask you whether you want to set its location as private or as public. If you choose Yes , you will “allow your PC to be discoverable by other PCs and devices on this network” , and it’s what you should do if you are connecting to your home or work wireless network. If you are connecting to a public wireless network, choose No. If you don’t choose anything and simply close this dialog, you should know that Windows 10 will set this new network as public, by default. 
 
Once you have done this your device is finally connected to the internet.

Warning: Be very careful if you connect to unsecured wireless networks such as wifi ‘hotspots’ in public places. While on them, it’s important not to use websites that require you to enter personal or financial details as other users of the network could gain access to these details.
