Improve your Wi-Fi signal using a soda can
MAKE blog shows us how to improve a wifi signal using just a soda can. Just clean the can, remove the tab, cut out the bottom, create a base, slice up the side and attach it to your router. More details are given on MAKE but that's essentially it. It's basically like adding foil to TV antennas, only for today's tech. Gotta love simple fixes using repurposed materials!
