How to Make a Signal Booster for WiFi for Free

Something as simple as aluminum foil can boost your Wi-Fi signal.

You need a signal booster for your home's Wi-Fi system if your Internet comes and goes or can't be accessed in all rooms. This happens in homes with thick walls or multiple levels. You could install a signal repeater or an external antenna and pay over $100. Or, you could download a free template and add some aluminum foil to make a parabolic reflector for less than 50 cents.
