People left mindblown after learning how tin foil improves your Wi-Fi

People left 'mindblown' after learning how tin foil improves your Wi-Fi connection.

A viral post suggests: 'Put an aluminium foil behind your router and thank me later!!!' While it might sound like nonsense, scientists say that this cheap trick really does work.

However, there's one important catch - it could make the connection in other rooms worse.

Another added: 'You could also fold the foil the shape of a hat and wear it wherever you go.' While one commenter joked: 'Why not put it in the oven too while we are at it.'.
