Best Router Placement in Your Home for Strong Wi-Fi
Where to put your router for the best Wi-Fi coverage in a UK home, what to avoid, and how to test positions without buying new equipment.
Router position is the cheapest Wi-Fi upgrade there is, and the one people try last. Many routers live where the broadband cable happens to come in: behind the TV, under the stairs or in a cupboard. A move of a few metres can change the whole house.
The principles
Wi-Fi radiates outward in all directions and weakens with distance and obstacles. Good placement follows a few simple ideas:
- Central. Place it as close as practical to the middle of where you use the internet.
- High. A shelf, not the floor, since signal spreads down and out more than up.
- Open. Keep it clear of cupboards, cabinets and thick furniture.
- Away from interference. Microwaves, cordless phone bases, baby monitors and large metal objects degrade the signal.
- Away from big water and metal. Fish tanks, mirrors, radiators and fridges reflect or absorb it.
Good and bad spots
| Spot | Verdict |
|---|---|
| Hallway shelf on the ground floor, central | Usually good |
| Landing in a two-storey home | Often a good compromise |
| Inside a TV cabinet | Poor |
| Behind a metal radiator or mirror | Poor |
| Next to the microwave or cordless phone | Poor |
| Under the stairs or in the meter cupboard | Poor |
| Corner of the house, far room | Poor for whole-home coverage |
The problem of the master socket
In many UK homes the phone or fibre socket is in an inconvenient place, so the router sits there. You have options:
- Use a longer cable between the socket and the router, if the setup allows it.
- Move the router and connect it to the socket via an extension lead made for the purpose.
- Keep the router where it is and add an access point or mesh unit elsewhere, wired if possible. See mesh Wi-Fi versus extenders.
Fibre set-ups with a separate optical unit may limit movement, so check what your provider's equipment allows, or ask a technician. Do not alter the provider's equipment in ways their terms disallow.
How to test positions properly
- Pick two or three candidate spots.
- At each, run a speed test in the same rooms, noting the results. The method in testing broadband speed properly helps.
- Test at similar times of day, as evening congestion can confuse results.
- Compare, and pick the best overall rather than the best for one room.
Even moving the router a metre away from a wall or off the floor can show a noticeable difference.
Antennas and orientation
If your router has adjustable antennas, set them at different angles, with one upright and one at forty-five degrees or horizontal, so devices in both horizontal and vertical orientation get a good signal. For floor-to-floor coverage, vertical antennas push signal sideways and horizontal ones push it up and down.
Other quick improvements
- Update the firmware and restart occasionally.
- Change channel if your neighbours' networks overlap.
- Use wired connections for TVs, desktops and consoles that do not move, which also frees Wi-Fi capacity.
- Check for a slow device dragging down others.

When broadband is the real issue
A perfect position will not rescue a slow line. If speeds are poor right next to the router, the fault is outside your walls and is a matter for your broadband provider.
Getting help
A technician can survey the property, suggest the best location and run cable if needed. On Compito you can search by postcode, compare ID-verified local providers and send a request describing your layout. You receive an offer you can accept and pay online and message the provider to agree what will be done. See tech support services.
A worked example: a three-bed terrace
Imagine a typical two-storey terrace where the fibre socket is in the front room and the router sits behind the TV. The bedroom at the back of the upstairs floor gets a weak signal, and video calls stutter. Moving the router a few metres to the shelf at the top of the stairs, or to the hallway, puts it roughly in the middle of the house in both directions. Nothing was bought, yet the far bedroom often goes from patchy to usable. Where the move is not possible because of the socket, a wired access point on the landing is the next step.
Materials that block signal
Not all walls are equal. As a rough guide:
- Plasterboard and timber stud walls let most signal through.
- Brick and breeze block absorb a fair amount, so each wall costs you range.
- Thick stone, older solid walls and chimney breasts can be very difficult, especially in period properties.
- Foil-backed plasterboard and insulation, metal doors and underfloor heating mats reflect or soak up signal more than you would expect.
- Glass with a metallic coating, common in modern double glazing, can also weaken it.
Count the walls between the router and the room you care about. Two or more solid walls is often where trouble starts.
Common mistakes
- Leaving the router on the floor behind a sofa.
- Stacking it on top of other electronics such as a set-top box, which runs warm and adds interference.
- Standing it right beside a window, so a good share of the signal goes into the garden.
- Hiding it in a cupboard for appearances and then blaming the provider.
- Moving it, then forgetting to compare results with a proper test.
Flats, small homes and shared buildings
In a flat, central placement matters less than in a house, but neighbours matter more. Dozens of networks competing on the same channels cause slowdowns even at full signal strength. A position away from shared walls and a less crowded channel often help. In a small flat, a router in the main living space with the door open to the bedroom usually works well.
Placement for homeworking
If you work from home, prioritise the room where you take calls. A cable from the router to a desk, or a small wired network switch, gives a steadier connection than any position tweak.
Frequently asked questions
Should the router be upstairs or downstairs?
Central to where you use it is best. In a two-storey home, a landing or a high shelf near the middle often serves both floors reasonably well.
Does hiding the router in a cupboard matter?
Yes. Enclosures, especially metal ones, cut signal significantly. Move it to an open space where possible.
Can I point the router at the dead spot?
Not really. Wi-Fi spreads in a broad pattern, so position and obstacles matter more than aiming.
