Best Wi-Fi Router Placement

Most people put their router wherever the cable installer first dropped it. Usually behind a TV, in a closet, or in a corner. Moving the router is the single biggest free Wi-Fi upgrade you can do.

Why placement matters so much

Wi-Fi signal radiates in all directions from the router. Each obstacle between the router and your device weakens the signal:

• Drywall: 15% loss per wall
• Brick or concrete: 50-75% loss
• Glass: minor loss
• Metal (refrigerators, file cabinets): nearly total block
• Water (fish tanks, water heaters): big absorption
• Mirrors: reflect signal in weird ways

Moving the router 6 feet can mean the difference between full bars and a dead zone.

Best place: central, elevated, open

1. Central: middle of the house. Not the corner
2. Elevated: 3-5 feet off the ground. Top of a bookshelf, mounted on a wall, on a side table
3. Open: not in a closet, not behind a TV, not in a cabinet
4. Vertical clearance: ideally a few feet above floor and a foot below ceiling

Common mistakes

• Inside a closet or cabinet: walls block 30-50% of signal
• Behind a TV: the TV is full of metal and electronics that absorb and interfere
• On the floor: furniture and your body block signal going outward
• Next to the microwave: microwaves use the same 2.4 GHz frequency. Running one tanks Wi-Fi nearby
• Near a fish tank or water heater: water absorbs Wi-Fi
• In the basement: two floors of signal loss means weak Wi-Fi on the top floor
• Right next to baby monitor / cordless phone: they share frequencies

Position the antennas

If your router has external antennas:

• For a single-floor home: antennas vertical
• For multi-floor: one antenna vertical, one horizontal (Wi-Fi radiates in a flat plane perpendicular to the antenna)

What if I can't move the router?

If your modem/router has to stay where the coaxial cable enters, you have options:

1. Add a mesh node or extender: place it in a more central location with the router connected as the backhaul
2. Run an Ethernet cable to a better spot for a second access point or mesh node
3. Use MoCA adapters to use your home's coaxial cabling to extend the network
4. Powerline adapters if you have older houses without good wiring

Test the difference

1. Run a speed test in each room with the router in its current location (use fast.com or speedtest.net)
2. Write down the results
3. Move the router
4. Re-test the same rooms
5. Compare

The 5 GHz vs 2.4 GHz tradeoff

Most modern routers broadcast on two frequencies:

• 2.4 GHz: longer range, slower speeds, more interference (microwaves, baby monitors)
• 5 GHz: shorter range, faster speeds, less interference

5 GHz is great when you're close to the router. 2.4 GHz works better in distant rooms. Most routers automatically pick the right one (or you can split them).

For multi-floor homes

One central router rarely covers a 2-3 story house well. Options:

• Mesh system (Eero, Google Nest Wifi, TP-Link Deco): one node per floor
• Wi-Fi extender for one specific dead zone (cheap but slower)
• Wired access points if you have Ethernet runs (best)
