If your Wi-Fi router's signal is dragging in certain parts of your house, the solution might just be in your kitchen drawer.
Standard, 0.024-millimeter-thick household aluminum foil was shown to be just about as good as other, more expensive signal-reflecting metals like copper and silver, according to computer scientists at Dartmouth University.
The researchers masterminded a simple hack that promises not only to improve your wireless signal, but can even strengthen your cybersecurity, for about as much money as it costs to wrap your leftovers.
Crazy as it may sound, a 'tinfoil hat' on your router may also help you be less paranoid about hackers sneaking on to your wireless network.
