Using WiFi cuts broadband speeds by an average of 30 per cent, and can be worsened by microwaves, baby monitors and other radio devices Using WiFi to access the internet can slow broadband speeds by up to 40 per cent and by an average of 30 per cent, a new survey of 14,000 people across Europe has found.

The study, by internet analysts Epitiro, also found that using baby monitors, microwaves, cordless phones, video games consoles and other devices that use the radio spectrum all had a significant impact on WiFi speeds.

Although it has long been accepted that using WiFi does not produce speeds as high as those available through the fixed line internet, it had not been previously thought that the decline in quality was quite so obvious in a domestic setting. Across Europe, the average drop was 30 per cent, reaching as high as 40 per cent in Italy. The UK average was 26.5 per cent.

Although Epitiro’s research suggested that for normal web browsing and email the drop in broadband speeds was unlikely to be a problem, streaming video and online gaming, which is more intensive, could be severely affected.

“Our data shows that connectivity over WiFi degrades broadband performance considerably in typical circumstances.” said the company’s Chief Technology Officer JP Curley. "Consumers who are experiencing performance issues with WiFi should take steps to improve their home environment or connect directly via wired ethernet.”
