As more devices connect in our homes, Wi-Fi speeds can slow down, especially during peak hours. Professor James McQuiggan

suggests a simple hack to improve Wi-Fi speed: placing aluminum foil behind your router. The Theory: When multiple devices

connect, the signal weakens, spreading in all directions. Obstacles like walls and furniture further reduce the signal. Placing aluminum foil behind the router with the shiny side facing out reflects the signal, helping it travel more effectively. Testing the

Theory: A Dartmouth research team confirmed McQuiggan’s idea, boosting the signal in targeted areas by over 50%. How to

Try It: Use a 1-foot sheet of aluminum foil. Shape it into a “C” and place it behind the router, shiny side inward. Run a speed
test to check the connection. Additional Benefits: This hack might also help with security by limiting the Wi-Fi signal range.

Results May Vary: Factors like space size and internet plan can affect its effectiveness. Alternatives, like Wi-Fi extenders, may

be more reliable. Other Tools: Metal items like baking sheets or beverage cans can also work, if shaped and positioned correctly. While not guaranteed, this simple hack is worth trying before considering more expensive options
