Extend and strengthen your Wi-Fi router's signal by fashioning a couple of tinfoil parabolas and putting them on your antenna. The experts at DL.TV demonstrate how to make a couple of "Windsurfers" for your home router so the signal makes it all the way to the basement. The guys in the vid said the parabola doubled his signal strength; our own Kyle said he only saw about a 5% gain—either way, worth it for the cost of glue, paper, and tinfoil. Here's the parabolic template for printing out your own "Windsurfer."
