Plenty of factors can impact your broadband speed including:
The type of connection – There are three main connection types: ADSL, fibre to the cabinet (FTTC) and fibre to the premises (FTTP). The speeds of each vary massively, with FTTP – or full fibre – offering the fastest speeds.
How many people are online – If several people in your household are online at the same time, the bandwidth is being split between all of you.
How you use the internet – Activities like streaming HD content and online gaming use a lot of bandwidth.
Your WiFi hub – Walls and solid surfaces could weaken your WiFi signal.
Wired vs wireless – Wired connections are more reliable because you’re plugged straight into the source.
