The Best Place to Put Your Router (and the Worst)

Before you spend a cent on a new router or a bigger plan, move the one you have. Placement is the most underrated Wi-Fi upgrade there is, because it's free and it works with physics instead of against it. A router shoved in a closet in the corner of the house is fighting a losing battle no hardware can win.

How Wi-Fi signal actually travels

A router broadcasts roughly in a sphere, radiating outward and, notably, downward. The signal weakens with distance and loses strength every time it passes through something solid. Not all obstacles are equal — drywall is nearly transparent, but concrete, brick, tile, metal, and water are signal-killers. That last one is why a person's body, or a fish tank, absorbs surprisingly much.

The best spot

• Central — as close to the middle of the area you use as possible, so coverage reaches outward evenly instead of wasting half the sphere on the yard.
• Elevated — up on a shelf, not on the floor. Since signal spreads down and out, a high router covers a floor far better than a low one.
• Open — out in the room, not inside a cabinet or entertainment center. Enclosures, especially anything with metal, badly muffle the signal.
• Away from interference — keep distance from the microwave, cordless phone bases, baby monitors, and big metal appliances.

The worst spots

If your router lives in any of these, that alone may be your whole problem:

• On the floor in a corner — this wastes most of the signal on the walls and the outdoors.
• Inside a closed cabinet or TV console — the enclosure absorbs a large share of the signal.
• In the basement — you're then trying to push signal up through the densest part of the house.
• Right next to the microwave or a stack of electronics — constant interference.
• Behind a large metal object or an aquarium — metal reflects and water absorbs Wi-Fi.

When placement isn't enough

Placement can only do so much in a genuinely large or awkward home. If you've centralized and elevated the router and the far bedroom is still weak, the problem is coverage area, not position — and the fix is a second broadcast point. A mesh system adds nodes that hand devices off seamlessly as you move; a wired access point in a distant room does the same job even better if you can run a cable to it.

Prove it with a test

Turn placement into measurement. Run a speed test in your weakest room, move the router to a better spot, and test the same room again. Because you're changing one thing and measuring the same place, the result is honest — and it often reveals that a few feet of repositioning bought you more than a hardware upgrade would have.
