Routers end up wherever the line enters the house, which is usually a hallway corner near the front door, often inside a cupboard, at floor level, behind coats. That is close to the worst possible position, and moving it is the cheapest meaningful Wi-Fi upgrade available.
The short answer
Central, high and in the open. A router in the middle of the house at waist height or above, with clear air around it, covers dramatically more than the same router in a corner cupboard at floor level. Try it for a week before spending anything on mesh or extenders.
How a router actually radiates
A router with internal antennas radiates outward in a flattened doughnut shape, strongest to the sides and weakest directly above and below. Two consequences follow:
- Height matters. A router on the floor sends much of its signal into the floor. Raising it to waist height or above puts more of that energy into the rooms you use.
- Central beats corner. In a corner, half the coverage is going into your neighbour’s house or the garden. In the middle, all of it is in your house.
External antennas can be angled, and the usual advice for a two-storey house is one vertical and one horizontal, which spreads coverage both across the floor and upward.
Map your current coverage
Walk the house noting signal strength in each room. Write the numbers down. Without a baseline you cannot tell whether moving it helped.
Identify the centre of your usage, not the house
The geometric middle matters less than the middle of where people actually are. A bedroom nobody uses does not need coverage; the sofa and the desk do.
Get it off the floor
Waist height or above. A shelf, a table, the top of a bookcase. This single change often produces the biggest improvement.
Get it out of the cupboard
An enclosed cupboard, particularly one with a solid door, blocks signal and traps heat. Both matter. If it must live there, leave the door open or remove the back panel.
Move it away from metal and water
Radiators, filing cabinets, fridges, boilers, mirrors and fish tanks all block or absorb. A metre of clearance from anything large and metallic is worth having.
Move it away from other 2.4 GHz devices
Microwaves, cordless phone bases, baby monitors. A metre helps considerably, and away from the kitchen entirely helps more.
Angle external antennas if it has them
For a single floor, all vertical. For two floors, one vertical and one horizontal. Antennas radiate perpendicular to their length, so a vertical antenna covers the floor it is on.
Re-measure and compare
Walk the same route and compare numbers. If the new position is better in the rooms that matter, run a longer cable and make it permanent.
You are not stuck with where the line enters the house. A longer cable from the wall socket to the router moves it wherever you want, and for most connection types the cable run is inexpensive and does not degrade the signal meaningfully over household distances. That one realisation unlocks the whole exercise.
Placement mistakes worth checking
- Inside a media cabinet with other equipment. Blocked and hot.
- Behind the television. A large flat metal-backed object directly in front of the antennas.
- On the floor behind the sofa. Absorbed by furniture and people.
- Next to the boiler or the fuse box. Metal and electrical noise.
- On a windowsill. Half the signal goes outside, and the sun cooks it.
- In the garage or utility room at one end of the house.
- Stacked on top of a set-top box. Heated from below and shielded.
Keep the router in open air for heat as well as signal. Routers are passively cooled and run continuously, and one in an enclosed cupboard will degrade over time and misbehave on warm afternoons. Placement fixes two problems at once.
Multi-storey houses
Signal travels through floors reasonably well, better than through some walls. In a two-storey house, a router on a shelf in an upstairs hallway often covers both floors better than one in a downstairs corner, because it is radiating downward through the ceiling into the middle of the ground floor.
In a three-storey house, one router will usually not be enough regardless of placement, and that is where mesh or a wired access point genuinely earns its cost. Even then, placing the main unit on the middle floor makes the job easier.
When placement is not enough
If you have measured, moved the router to a central elevated open position, and there are still rooms with unusable signal, the problem is the building rather than the position. Stone walls, foil-backed insulation and long narrow layouts all defeat a single router.
At that point mesh or a wired access point is the answer, and you will place those better for having done this exercise, because you now know where the signal actually falls off.
Where is the best place for a router?
Central to where people actually are, at waist height or above, in open air. Away from metal, water, and other 2.4 GHz devices.
Does router height really matter?
Considerably. Routers radiate in a flattened pattern, strongest to the sides. One on the floor sends much of its signal into the floor.
Can I move my router away from the wall socket?
Yes. A longer cable from the socket to the router is inexpensive and does not degrade the connection over household distances. Most people never realise this is an option.
How should I angle external antennas?
All vertical for a single floor. One vertical and one horizontal for two floors, since antennas radiate perpendicular to their length.
Is a cupboard really that bad?
Yes, for signal and for heat. A router in an enclosed cupboard loses coverage and runs hot, which shortens its life and causes instability on warm days.
The bottom line
Measure first so you can tell whether a change helped. Then get the router central, high and in the open, and remember that a longer cable lets you put it wherever you want rather than where the line happens to arrive. Try it for a week before buying mesh, because for a lot of houses this is the whole fix and it costs the price of a cable.
