An ISP is an organisation that supplies services, such as data and voice, that work in conjunction with the fibre infrastructure supplied by the FNO.

I have poor signal strength in my home, what do I do?2020-04-19T16:22:29+02:00

Poor signal strength could be due to signal-blocking materials in your home’s walls.

Here are a few ways to improve your signal strength.:

  1. Wi-Fi range extender– This device repeats the wireless signal from your router to expand its coverage. It functions as a bridge, capturing the Wi-Fi from your router and rebroadcasting it to areas where the Wi-Fi is weak or non-existent – improving the performance of your home Wi-Fi.
  2. Ethernet over power- A Powerline network is essentially a wired network with hidden wires. You purchase a basic kit, which comes with two Powerline adapters and two short Ethernet cables. Connect one of the Ethernet cables to your router and the first adapter. Plug it into the nearest power socket and you should see an increase in your signal strength.

What is the difference between Fibre and ADSL?2020-04-23T15:42:45+02:00

ADSL (Asymmetric Digital Subscriber Line) uses telephone lines to transmit data along with copper cables – from the nearest telephone exchange to your home or office. The further you are from the exchange, the slower your speeds will be. Copper cables are also affected by the number of users utilising the internet at a single point in time, i.e. the more Internet traffic, the slower your download speeds.

Fibre Internet uses fibre optic cables to transmit data – meaning that data has the potential to travel at the speed of light and isn’t affected by your distance from the exchange. It can also handle much higher volumes of traffic without your download speeds being affected.

What is the difference between Fibre and LTE?2020-04-19T15:25:00+02:00

LTE (Long-Term Evolution) is a wireless internet connection. It can achieve speeds of up to 50Mbps. However, because it’s airborne’, speeds are more prone to being affected by external factors such as bad weather.

Fibre Internet uses fibre optic cables to transmit data meaning that data has the potential to travel at the speed of light. A more reliable internet connection – it’s not affected by external factors such as bad weather.
