Wifi + Aluminum Foil

My room is really far away from the wifi source in our house, and there are several walls in the way. As a result, the signal is so pathetic it's almost nonexistant. My computer occasionally refuses to connect. We heard something about using foil to "relay" the signal and improve its strength. My dad turned his bulletin board around and pinned aluminum foil to the back and placed it behind the router. As if by magic, my laptop now shows a signal strength of Good to Very Good and a speed of between 12.0-24.0 Mbps when it used to hover around 1.0. Wow, foil really does work! The deflector had directionality, though, so if you decide to use this method to give your wifi a boost, make sure it's pointing in the right direction before you get too far away.

Wifi + foil = speed
