What is Fibrefast Broadband?

It is a fibre connection going directly to your home or business and is not shared with other premises in the local area, know as FTTP or Fibre To The Premise.


What speeds can I expect from this new service?

Fibrus provide an asynchronous and unlimited service with a minimum delivery of 100Mbp download and 30Mbp upload.

How reliable will my speeds be?

We know how important a reliable broadband connection is to the modern family, now more than ever!

The good news is that you no longer have to tolerate unreliable speeds from old copper networks if your premise is included in our network. We deliver our Fibrefast Full Fibre Broadband directly to your door. Full fibre broadband delivers much faster speeds that are more reliable than copper networks, meaning that you can receive much faster download and upload speeds with Fibrus full fibre broadband.

However, a wide range of factors, such as distance from the router, thick walls and other wireless devices & electronics, can impact the Wifi signal in your home, leading to Wifi dead spots and lower download & upload speeds than expected when using wireless devices. The best way to maximise your download & upload speeds is to have a wired connection using an ethernet cable. However, we know that this is not always possible or practical. So to allow our customers to make the best of our fibrefast speeds we offer Mesh Wifi Boosters from £5 a month, which will limit the impact of any Wifi dead spots

What can impact or limit my Wi-Fi signal?

A variety of environmental factors can impact Wi-Fi signal including but not limited to; other wireless devices in close proximity to the router, metallic objects, thickness of walls, other electronic devices. In order to ensure the best Wi-Fi signal, routers should be set in an open area and as far away as possible from other electronic devices.

We also offer Wi-Fi boosters to extend Wi-Fi reach within your premises, if you would like Wi-Fi boosters please contact our customer service team on 02890 993230

Does it matter if I hard wired connection or wireless connection?

For best performance we would recommend a wired connection as this removes the possibility of interference from other devices and will provide the best and most reliable performance.

Can all of my devices benefit from the 1GB download speeds?

Our 1GB service is designed for homes and businesses with multiple high use devices, most individual wireless devices will not able to fully benefit from this speed as their maximum download speed is limited below 1GB.

Do I need to keep my existing telephone line?

No, as you will have fibre connected directly to your home you will no longer need a traditional telephone line. If you however use your telephone line for making and receiving calls, we can provide you with an excellent low-cost alternative using VOIP (voice over IP) Technology.

What is the cost of Fibrus VOIP & can I keep my existing telephone number?

Simple – its £10.00 per month which includes unlimited anytime calls and we port your number to our service free of charge. In addition, you can use your existing phone so no need to buy a replacement.

How to connect VOIP handset to router?

Connect your handset directly into the Fibrus router Tel1 port (left most grey port). When you received your router a VoIP adaptor should have been left. Your handset will plug into the adaptor which then plugs into the Tel1 port (left most grey port).

Why does my phone not ring when receiving calls?

There are 4 main reasons why this could happen:

Check to ensure the volume for ringtone is enabled and turned up.
Ensure your handset is connected directly into the Fibrus router Tel1 port (left most grey port).
Ensure you are using the correct cable that came with the handset
This could be caused by the handset being designed for the old copper network which was powered by the copper line. On modern VoIP systems the handset must provide power to the ringer from its own power source.
If you have tried these 4 solutions and are still having issues please contact our customer service team on 028 90 993 230
