WiFi Router's Signal: Does aluminum foil boost your WiFi router's signal? Expert reveals the truth...

Low Wi-Fi speeds are a common problem at home. Sometimes it's buffering while watching movies, or sometimes the signal is weak during meetings. In such situations, people sometimes reposition their routers, sometimes even replace them altogether. However, you've probably heard that aluminum foil boosts Wi-Fi router signals. This may sound strange, but this theory holds water. But can aluminum foil really boost Wi-Fi signals? Let's find out what research and experts have to say about this.

What did the scientists say?

A report in Reader's Digest states that scientists at Dartmouth College conducted tests. They created a shape covered with foil. In some areas, the signal increased by 55%. In areas where it wasn't needed, it decreased by 63%. This improved overall coverage. Research has proven that aluminum foil, when used correctly, can boost Wi-Fi signals. Jia Zhou, a computer science professor at Dartmouth University and the lead scientist on this study, says that aluminum foil bounces Wi-Fi signals.

How does aluminum foil work?
Routers have antennas that transmit signals. These signals spread like radio waves, just like a sprinkler spraying water around. This weakens the signal. Walls, floors, and windows block it, and some areas simply don't reach the signal. In such cases, roll up aluminum foil and place it behind the router, with the shiny side facing inward. This reflects the signal, allowing it to travel in the direction it needs, such as the living room or bedroom. Any signal traveling toward the window is blocked, increasing speed.

Reduces the risk of hackers
Aluminum foil keeps the signal contained within the home, preventing it from escaping. This reduces the risk of hackers. They can intercept the signal and steal data. It provides additional security along with password protection, maintaining privacy at home. While this hack isn't perfect for everyone, it's still a cheap and easy method. You might want to try it before purchasing a Wi-Fi extender.
