Use aluminum foil to boost your home Wi-Fi signal

tomsguide.com

A simple aluminum foil reflector can improve Wi-Fi signal strength in dead zones. The foil, shaped into a parabolic curve, redirects signals that would normally broadcast away from desired areas, focusing them forward. This hack is most effective when the router is near a wall or corner. Research from Dartmouth College supports this method, which works by reflecting radio waves. It is a low-cost solution for uneven Wi-Fi coverage, but does not fix underlying issues like slow internet plans.
