Scientists reveal simple hack that can improve your Wifi in minutes [View all]

Scientists have revealed a simple trick that can improve your wireless signal and even strengthen its security, all for under $40 – and, it could outperform antennae that cost into the thousands.

The new technique relies on a 3D-printed reflector wrapped in aluminium foil, which directs the signals toward specific areas, and away from places they’re not needed.

While the device works best with the 3D printed material, as it can more accurately capture and maintain the optimal shape for the desired coverage, the team also says you can create a similar structure using cardboard.


The inexpensive technique developed by researchers at Dartmouth College and Columbia University essentially creates a ‘virtual wall’ to improve Wifi signal in indoor spaces with multiple rooms.

Shaping the signal allows users to funnel the Wifi toward the areas it’s most needed.

This, according to the team, can reduce interference and the signal-deadening effect of building materials, and even increase the system’s protection against cyberattacks by limiting the signal to certain spaces.
