Football fans who want to follow Euro 2016 online could be in for a frustrating summer, thanks to inadequate broadband connections.
According to Boosty, nearly one in four households in the UK feel their internet connection is too slow and unreliable during a typical evening.
As a result, it believes people who want to follow Euro 2016 online could struggle to keep up with the action throughout key fixtures, Mobile News reports.
Recent years have seen more and more people turn to connected devices to enjoy live sport.
Indeed, figures from Fifa showed that 280 million people across the globe relied on the internet to watch the World Cup in Brazil two years ago.
Paul Evans, Chief Executive of Boosty, commented: "Almost 40 per cent of households now have five or more connected devices competing for internet access at any given time, but dodgy broadband connections mean football fans streaming the Euros could be left sweating."
"Imagine the rage fans will feel if they miss a crucial Rooney penalty due to a frozen screen, or they get the dreaded spinning wheel of death just as Vardy is through on goal."
Mr Evans has therefore urged football fans to find out straight away whether or not their broadband is fit for purpose, as there is "still time to invest in a tech fix" to boost broadband speeds.
He added that Euro 2016 is part of a bumper summer of sport this year, as Wimbledon and the Olympic Games are also just around the corner.
Euro 2016 kicks off on Friday June 10th and three home nations - England, Wales and Northern Ireland - have qualified.
