Boost Your Wireless Signal With a Homemade Wifi Extender

It’s amazing what a few sheets of tin foil can do for the strength of your wireless signal. As shown above, by carefully folding tin foil 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 3 minutes and hopefully leave you with impressive results. If you don’t want to attach unsightly parabolic boosters and you’re using the same basic router as the fellas in the video, you can also upgrade your firmware to DD-WRT—a free hack that will turn your $60 router into a $600 router and allow you to boost your WiFi signal from your router’s control panel.
