If you have a large house, and your wireless signal is not cutting it…It’s amazing what a few sheets of tinfoil can do for the strength of your wireless signal. By carefully folding tinfoil into a parabola, you can boost your wireless strength tremendously. The fellas in the video saw gains from 82% to just under 100%, though I only saw boosts of around five percent, so your mileage may vary. This project should only take about three minutes and will hopefully leave you with impressive results.
