What’s the difference between WiFi and fibre internet?

The internet is a global network that connects billions of computers. It provides users with access to a broad array of information and online services, such as social media sites, games, video streaming services, emails, business services and web pages. People often use the terms ‘WiFi’ and ‘fibre’ interchangeably, but they are not the same thing.

Wi-Fi is a wireless networking technology that allows devices, like computers and other electronics, to wirelessly connect to the internet through radio waves. Users can connect their devices to wireless access points or routers in order to access websites and online platforms. 

The WiFi router connects directly to a fibre optic cable – simply called fibre, which transmits data in the form of light pulses. Fibre is the physical cable that connects a house or office to the local data centres, whereas WiFi is the device used to wirelessly connect devices to the fibre cable. 

WiFi signal may vary in strength

What's the difference between WiFi and fibre internet?

Like many types of connection, WiFi can experience lapses in signal strength. Here are a few reasons why your WiFi may weaken from time to time:

  • Your connected electronic device may be too far away from the WiFi router.
  • You may have too many devices connected to the WiFi at once. 
  • Certain appliances can interfere with WiFi, such as satellite dishes, cordless phones, microwaves and baby monitors. 
  • Physical barriers can affect WiFi signals, like walls and closed doors.
  • Your router or plug may be faulty. 

Fibre, on the other hand, is far more dependable as it does not rely on wireless signals. When fibre is interrupted it is usually due to maintenance, repairs or physical breakage of the fibre optic cables. If you experience any problems with your internet and you suspect the WiFi is not to blame, get in touch with a professional internet service provider to resolve these problems.
