Video: How a bit of tin foil can instantly boost your home Wi-Fi connection


Scientists claim there is a really simple way you can improve your Wi-Fi connection.

While it may sound far fetched to some, all you need is a bit of tin foil.

The claims come after scientists tested a new 3D printed reflector wrapped in a sheet of tin foil.

The contraption works by directing Wi-Fi signals towards a specific area and away from areas where they are not needed.

During tests, the contraption worked best with the special 3D printed material but scientists claim anyone can make a similar shaped structure out of cardboard and it will still boost your Wi-Fi signal.

For only $35 and 23 minutes, Wi-Fi users can increase signal strength and boost security in offices and homes.

The inexpensive contraption was created by scientists from Columbia University and Dartmouth College who teamed up to develop a “virtual wall” that helps to improve a Wi-Fi signal inside an indoor space with multiple rooms.

By adding the home homemade contraption to a Wi-Fi router, the scientists say users can funnel the Wi-Fi signal towards an area where it is needed most.

This helps to cut out interference from building materials and other devices that may be weakening your Wi-Fi connection.

“Through this single solution, we address a number of challenges that plague wireless users,” Xia Zhou, an assistant professor of computer science at Dartmouth College said.

“Not only do we strengthen wireless signals, we make those same signals more secure.”

A video demonstrating the hack was posted on YouTube by Jusin Chan who was part of the research team.

“Cardboard would act as a reasonable substitute for the 3D printed substrate,” Justin said.

“However, it is not easy to bend the cardboard to conform to an arbitrary pattern + the cardboard may bend out of shape.”
