Discover a simple and economical method to improve your Wi-Fi performance by placing a sheet of aluminum foil behind your router.
How can aluminium improve your Wi-Fi connection?
When you use Wi-Fi, the signal spreads in all directions, even where it’s not needed, which can disrupt the connection in important areas of your home. By placing a sheet of aluminum foil behind your router, you can act as a reflector, redirecting the signal to key areas and reducing unnecessary diffusion.
The benefits of this method
Researchers at Dartmouth University experimented with this technique using 3D-printed structures on aluminum surfaces. Their results showed a signal increase of up to 50% in targeted areas, as well as a 60% signal decrease where it wasn’t needed. Furthermore, using aluminum can enhance the security of your Wi-Fi connection.
