Router Placement: 7 Mistakes That Are Killing Your Wi-Fi

Even an expensive router can provide poor Wi-Fi if it is in the wrong spot. Placement is one important factor in home internet, because Wi-Fi is radio — and radio is affected by walls, metal, and distance. Here are seven common mistakes, and how to check them.

Before and after each change, run a speed test in your problem room so you can see the improvement in real numbers.

Mistake 1: Hiding the router in a cabinet or closet

Tucking the router behind cabinet doors, inside a media console, or in a closet places extra material between the radios and your devices. Wood and metal can attenuate or reflect a signal, depending on the construction.

Fix: Put the router in an open location where practical. If you need to hide it, avoid enclosing it in a metal cabinet and re-test the problem room after moving it.

Mistake 2: Putting it on the floor

Wi-Fi coverage depends on the router's antenna pattern, the building, and the client. A floor-level location can be obstructed by furniture and may provide poorer coverage than an elevated, open location.

Fix: Elevate it — a shelf, a desk, or a wall mount — and re-test coverage on the same floor.

Mistake 3: Shoving it in the corner of the house

A router in the far corner of your home can leave the opposite end with a weaker signal while coverage extends into areas you do not use.

Fix: Move it as central as you can to where you actually use devices. A central router covers far more living space with the same hardware. Run a longer cable from the modem if you have to — it's worth it.

Mistake 4: Right next to the microwave (and other interference)

Microwave ovens, cordless phones, baby monitors, and Bluetooth devices can add activity in or near the 2.4 GHz band. A router parked next to them may see more interference when they are active.

Fix: Keep a few feet of clearance from the microwave and other electronics. Where possible, connect devices to the 5 GHz band, which is far less crowded.

Mistake 5: Surrounding it with metal and water

Metal can reflect Wi-Fi and water can absorb it. A router behind a big TV, next to a filing cabinet, near a fish tank, or beside a refrigerator may have a less favorable radio path. Mirrors with metal backing can also attenuate a signal.

Fix: Give the router open air. Move it away from large metal appliances, aquariums, and mirrors.

Mistake 6: Ignoring the antennas

If your router has external antennas and they're all pointed the same way, you may not get the coverage pattern you need. Antennas radiate outward perpendicular to their length.

Fix: For a two-story home, position antennas at different angles — one vertical, one horizontal — so you cover both the same floor and the floor above. For a single story, vertical antennas spread the signal outward across the level.

Mistake 7: Expecting one router to cover a large or multi-floor home

There are practical coverage limits. One router may not cover a large or multi-story home evenly, even after careful placement. A more powerful model is not always the right answer when the problem is coverage area.

Fix: Use a mesh system — two or three units that can hand devices off as you move around. For a wired backhaul to a far room, a MoCA or powerline adapter feeding a second access point may be a better fit, depending on the home's wiring.

The 10-minute optimization

1. Test your speed in your worst room and write it down.
2. Move the router: open, elevated, central, away from metal and the microwave.
3. Angle the antennas for your home's layout.
4. Connect nearby devices to 5 GHz.
5. Re-test the same room and compare.

Repositioning can help before you buy hardware, but the result depends on the building and devices. Start with placement — then, if a large home still has dead zones, compare mesh, wired access points, and other coverage options. Spend on the part of the network your tests show is limiting.
