In today’s connected homes, a strong Wi-Fi signal is needed for work, gaming, and streaming. However, standard routers waste signals by broadcasting them in all directions, creating weak spots in your house.
Because aluminum foil is a metal, it acts like a mirror for Wi-Fi radio waves. Instead of letting the signal bounce away randomly, you can use the foil to bend and aim the internet right toward your devices.
A 2017 college study proved this trick actually works. Researchers found that using foil-covered shapes could boost internet signals by over 50% in chosen rooms, while also keeping the Wi-Fi from leaking outside your home.
To try it, cut a piece of foil about one foot square and curve it into a smooth “C” shape. Place it right behind your router’s antennas, facing the room where you need better Wi-Fi, and test your speed.
