The “up to” speeds advertised and listed on broadband deals don’t really reflect the actual speeds most of us will get from our broadband.
The “up to” speed is the maximum possible speed that a type of connection can support, even though you’re unlikely to come close to that speed in the real world.
You’ll see this written out as “up to 17Mbps” for ADSL standard speed broadband, “up to 38Mbps” and “up to 76Mbps” for Fibre to the Cabinet, “up to 50/100/200/300Mbps” for Virgin cable broadband and “up to 1Gbps” for gigabit full fibre broadband.
There are a variety of reasons why broadband speeds slow down and you can’t get the maximum “up to” speed on your home broadband.
The top two reasons are electrical interference, and the broadband ‘rush hour’ that occurs at peak times, just before and after work and school, when a lot of people are all trying to use broadband connections at the same time.
Full fibre is much less likely to suffer from this interference, as it uses ONLY fibre-optic cables to deliver your broadband, without slow copper as part of the connection.
