Where should you put your Wi-Fi router?
Short answer: Put your Wi-Fi router in a central spot, off the floor and out in the open, such as a shelf or bookcase top at roughly eye level. Keep it out of closets, cabinets and basements, and several feet from metal objects, fish tanks and microwaves. If rooms two or more walls away still drop out, add a mesh point.
What is the best place for a Wi-Fi router?
The short version from router makers: central, high and open. TP-Link says to place the router “centrally, up high, and out in the open.” Google’s Nest Wifi help page says the same thing in different words: “off the ground and in plain view,” at a “central location” at eye level.
A router sends signal outward in every direction. If it sits in a corner or against an exterior wall, a large share of that signal goes outside. TP-Link warns that near an exterior wall, roughly half the signal can end up pushing outside toward the neighbors.
In a two-story home, TP-Link suggests mounting the router on the upper part of the ground floor so it covers both levels. Pick a dry, ventilated spot, since routers make heat.
Your modem location limits your choices. The router has to reach the modem by Ethernet. A longer Ethernet cable is often the cheapest upgrade you can make.
Where should you NOT put your router?
TP-Link lists these spots to avoid:
- Basement, where concrete walls weaken the signal
- Inside a closet or cabinet, which blocks signal and traps heat
- Behind the TV, since TVs absorb Wi-Fi signal
- On the floor, which sends much of the signal downward
- In a corner or against an exterior wall
- Right next to another router
Kitchens and bathrooms are also poor choices. TP-Link warns that humidity there can damage internal parts. Keep the router away from radiators, sunny windowsills and hot stereo receivers too.
Safety note: do not stack items on top of a router or pack it into a sealed cabinet. It needs airflow to shed heat. Keep it away from sinks, aquariums and anything that could spill on it.
What household objects block Wi-Fi?
| Obstacle | Effect | Source |
|---|---|---|
| Large metal objects (refrigerators, filing cabinets, metal furniture, TV mounts) | Reflect or absorb signal | TP-Link |
| Metal-frame mirrors | Reflect or absorb signal | TP-Link |
| Fish tanks / aquariums | Water can create a coverage gap | TP-Link, Google |
| Concrete walls (often basements) | Weaken the signal | TP-Link |
| Walls and doors | Block line of sight between mesh points | |
| TVs | Absorb signal | TP-Link |
| Microwaves, baby monitors, cordless phones, Bluetooth devices | Interfere on the 2.4 GHz band | TP-Link |
TP-Link recommends keeping the router several feet from major appliances and large metal objects. Brick and stone walls may also weaken signal noticeably. Treat that as a general rule of thumb; neither source above rates specific wall materials.
Which way should router antennas point?
If your router has adjustable antennas, TP-Link gives this guidance:
- Single-story home: keep the antennas vertical.
- Two-story home: angle one antenna horizontally to help reach the other floor.
- Three antennas: point the middle one straight up and angle the outer two at about 45 degrees.
Routers with internal antennas cannot be adjusted. For those, placement matters even more.
Does 2.4 GHz, 5 GHz or 6 GHz reach farther?
TP-Link sums up the trade-off: 5 GHz gives faster speeds over shorter distances, while 2.4 GHz reaches farther but carries less bandwidth. The 6 GHz band, used by Wi-Fi 6E and Wi-Fi 7 routers, is generally expected to have the shortest range of the three, though neither source above covers it.
The general pattern: higher frequencies generally lose more signal over distance and through walls. Exact differences depend on the antennas, the devices and your walls, so treat any single dB figure with caution. In practice, 6 GHz often works best when your device is in the same room as the router or close by.
When is placement not enough?
Moving the router fixes many dead zones, but not all. Big homes, long floor plans, multiple stories and dense walls can beat even a well-placed router.
Google’s mesh guidance gives a useful benchmark. It says to keep mesh points “no more than 2 rooms away” from the router or another point. It also says to put each point “about halfway” toward the area that needs coverage. If you have rooms well past that distance, one router probably cannot cover them.
At that point, compare your options in our guide to mesh Wi-Fi vs. a Wi-Fi extender.
Quick answers
Should my router be high or low? High. Both TP-Link and Google recommend getting it off the floor, such as on a shelf or wall mount, ideally around eye level.
Can I put my router in a cabinet or closet? It is not recommended. Enclosures block signal and trap heat. If you must hide it, use an open shelf instead.
Does a microwave affect Wi-Fi? It can. TP-Link lists microwaves as a source of interference on the 2.4 GHz band. Keep the router several feet away, or use 5 GHz nearby.
Does a fish tank block Wi-Fi? Yes, water can create a coverage gap. Google lists aquariums as obstructions to avoid between Wi-Fi devices.
Should router antennas be vertical or horizontal? In a single-story home, keep them vertical. In a two-story home, TP-Link suggests angling one antenna horizontally.
