Are there Wi-Fi dead zones in your house? Before you do anything drastic, you might be able to fix it by simply moving your router.
This sounds fake, because Wi-Fi seems like magic—something that can only be made better by wizards who understand its mysterious ways. But Wi-Fi isn’t magic. Your laptop and iPad connect to the Internet using a century old technology: radio waves.
And radio waves have limits. If you drive through a tunnel with the FM radio on, you’ll mostly hear a bunch of static. This is because the signal from the radio tower can’t reach you underground. There are barriers that block the signal.
The same principle applies to your Wi-Fi: barriers between your router and your devices make the signal worse. So the physical placement of your device makes a startlingly big difference in your signal across the house.
Place Your Router in the Center of Your House
If you drop a pebble in a still pond, ripples move out from the impact point in all directions.
That’s more or less how radio waves work: they emanate from a central point, in all directions. Remember this when you place your router: imagine ripples moving out from the router in all directions.
With that in mind, the ideal position for your router should be as close to the middle of your house as possible. If your router is in one far corner of your house, you’re sending most of the “ripples” outside, where they aren’t really doing anything for you; meanwhile, the corner of your house furthest from the router is just picking up diminished ripples (or nothing). Put your router in the middle of the house to get equal coverage everywhere.
And remember to think three dimensionally, too. In a three-story house, it’s probably best to put the router on the second floor, assuming you want good signal on all three stories.
