Imagine that it’s a cozy Friday night and you’re all settled in to binge-watch your favorite show. You’ve got your snacks lined up, your most comfortable blanket handy, and you’ve snuggled into the perfect spot on the couch. There’s just one problem: Your Wi-Fi signal is dragging. Believe it or not, there’s a solution to that problem right there in your kitchen cabinet: aluminum foil. To reach all the devices in your home, Wi-Fi signals behave like radio or light waves, spreading out to cover every available space. Unfortunately, this can make the signals less efficient, weaken the connection, and could be one of the reasons your Internet is slow. Not only does it send Wi-Fi signals to parts of your home where you don’t need it, but it can also lead to dead zones in certain areas where the signals can’t reach or are blocked by obstructions like walls or floors. By placing a curved sheet of aluminum foil around the router, you can shape the flow of the Wi-Fi signals more effectively. The shiny side of the foil will reflect the beams coming from the antenna and point them at a specific place. From there, all you have to do is adjust the direction of the foil’s curve to steer the signal toward the parts of your home where you need a better Internet connection or direct it away from spots where it would be wasted, like a window.
