Router Placement Mistakes That Cost You Speed

28 Aug 2026

A fast broadband package and an expensive router cannot compensate for poor placement.

Your provider may deliver the advertised speed to the property, yet phones, laptops and televisions still suffer from buffering, weak signals or unreliable video calls because the router is hidden in the wrong place.

Wi-Fi uses radio waves. Those signals weaken with distance and lose strength as they pass through walls, floors, furniture and certain building materials. Electrical devices and neighbouring wireless networks can introduce further interference.

Router placement will not increase the speed entering your home, but it can determine how much of that connection reaches each room.

Here are the most common placement mistakes and what to do instead.

Mistake 1: Leaving the Router Where the Broadband Cable Enters

Internet providers normally install their equipment near the easiest external entry point. That might be beside the front door, in a corner of the living room or on an outside wall.

This location may be convenient for the installer but poor for wireless coverage.

A router positioned at one edge of the property sends a large portion of its signal towards the garden, street or neighbouring building rather than the rooms that need it.

Ofcom recommends placing the router centrally because Wi-Fi spreads in multiple directions. A central position helps distribute the signal more evenly around the property.

Better approach

Move the router towards the centre of the home where possible.

You may need:

A longer Ethernet cable between the broadband equipment and router
An extended fibre or modem connection installed professionally
A separate router connected to the provider’s equipment
A wired access point in a more suitable location
A properly designed mesh system

Do not move fibre or telephone cabling carelessly. Some provider connections require specific cables, settings or equipment.

Mistake 2: Putting the Router on the Floor

Routers are frequently left on the floor beside the broadband socket or underneath a desk.

That sends part of the wireless energy into the floor and places furniture, people and other objects directly in the signal path.

Ofcom advises positioning the router off the floor, such as on a shelf, so less of the signal is lost into the ground and nearby obstructions.

Better approach

Place the router:

On a desk, cabinet or shelf
Roughly at table height or above
In an open position
Away from clutter
Where its ventilation openings remain clear

Raising the router by even a metre can make a noticeable difference in some homes.

Mistake 3: Hiding It Inside a Cupboard

Routers are not usually attractive, so people hide them inside:

Television cabinets
Under-stairs cupboards
Sideboards
Utility cabinets
Wardrobes
Media units

The cabinet itself becomes another obstacle. When it contains metal, glass, electronics or wiring, the effect can be worse.

Enclosed spaces may also trap heat, which can reduce performance or shorten the life of the equipment.

Google advises placing Wi-Fi equipment in an open area and avoiding objects that physically block the signal.

Better approach

Keep the router in the open.

When it must remain inside furniture:

Use an open-backed cabinet.
Avoid metal enclosures.
Keep the doors open during testing.
Provide adequate ventilation.
Place a wired access point outside the cupboard.
Do not stack other equipment directly on top of it.

A separate ceiling or wall-mounted access point is often the cleanest answer when network equipment needs to remain hidden.

Mistake 4: Placing It Behind the Television

The space behind a television may contain:

A large display panel
Metal mounting hardware
Streaming boxes
Games consoles
Audio equipment
Power supplies
Numerous cables

All of these can obstruct or interfere with Wi-Fi.

A television is also commonly placed against an outside wall or in the corner of a room, making it an especially poor central access-point location.

Better approach

Position the router beside or above the television rather than directly behind it.

Where possible, connect fixed equipment to Ethernet:

Smart television
Games console
Streaming player
Audio receiver

Wired connections improve those devices while reducing the amount of traffic competing for Wi-Fi.

Mistake 5: Putting It in the Corner of a Room

A corner wastes coverage in much the same way as placing the router at one edge of the house.

Two nearby walls immediately restrict the routes available to the signal. The problem becomes worse when the corner contains a chimney breast, thick masonry or metal pipework.

Router manufacturers similarly recommend a central position away from corners for maximum coverage.

Better approach

Move the router:

Away from the corner
Towards the middle of the room
Closer to the centre of the property
Higher and in the open

Even moving it a short distance can improve the signal path into an adjoining room.

Mistake 6: Placing It Beside a Microwave

Microwave ovens operate in the same general 2.4 GHz frequency range used by many Wi-Fi devices.

A properly functioning microwave should contain most of its energy, but it can still contribute to interference nearby, particularly when older equipment or weak Wi-Fi signals are involved.

The problem may appear only while the microwave is running.

Ofcom advises keeping routers away from electrical and wireless devices that may interfere with the signal.

Better approach

Keep the router away from:

Microwave ovens
Cordless-phone bases
Baby monitors
Bluetooth hubs
Wireless video transmitters
Large audio systems
Dimmer switches
Halogen lamps

When Wi-Fi drops only at particular times, note which nearby equipment is operating.

Mistake 7: Positioning It Beside Large Metal Objects

Metal can reflect or block wireless signals.

Common problem locations include:

Filing cabinets
Refrigerators
Radiators
Metal shelving
Boiler cupboards
Electrical cabinets
Large mirrors with metallic backing
Steel structural beams

A router placed on top of a metal cabinet may look elevated but still perform poorly because the signal pattern is being altered.

Better approach

Maintain space between the router and large metal surfaces.

Place it on a wooden shelf or non-metallic stand where possible.

When a room contains extensive metalwork, use Ethernet to position an additional access point on the other side of the obstruction.

Mistake 8: Putting the Router Beside the Boiler or Hot-Water Tank

Boiler cupboards are convenient because they often contain power and service routes. They are poor wireless locations because they may contain:

Metal tanks
Copper pipes
Pumps
Electrical controls
Thick doors
Heat

Water and metal are both difficult obstacles for Wi-Fi.

Excessive temperature can also affect the reliability and lifespan of the router.

Better approach

Use the cupboard for the modem, switch or patch panel only when it is dry and ventilated.

Install the wireless access point outside the cupboard using Ethernet.

This separates the best location for network equipment from the best location for radio coverage.

Mistake 9: Placing It Near an Aquarium

Water absorbs and weakens radio signals, particularly at Wi-Fi frequencies.

A large aquarium positioned between the router and a device can behave like a substantial barrier.

The same principle applies to:

Water tanks
Hot-water cylinders
Dense plumbing
People gathered between the router and device

Better approach

Move the router or aquarium so that the main signal path does not pass through a large volume of water.

A small change in position may let the signal travel around the obstruction rather than through it.

Mistake 10: Keeping It in the Basement

A basement router must transmit upwards through at least one floor before reaching the main living areas.

The floor may contain:

Concrete
Steel reinforcement
Insulation
Pipework
Underfloor heating
Electrical wiring

This can severely weaken the signal.

A basement may also be at one edge of the property rather than centrally positioned.

Router manufacturers advise avoiding basements, attics and closets when those locations prevent even coverage.

Better approach

Leave the incoming broadband equipment in the basement if necessary, but run Ethernet to an access point on the ground floor.

For larger properties, use one access point per floor or conduct a proper wireless survey.

Mistake 11: Installing It in the Loft

A loft seems central and keeps the router out of sight, but it creates several problems.

The signal must travel down through ceilings and insulation. Foil-backed insulation can be particularly disruptive.

Lofts also experience temperature extremes. Summer heat and winter cold may exceed the conditions for which ordinary consumer routers are designed.

Better approach

Use the loft as a cable-distribution route rather than the final router location.

Run Ethernet through the loft to ceiling-mounted access points installed inside the occupied rooms.

This keeps the equipment in a controlled environment while taking advantage of the loft for easy cabling.

Mistake 12: Expecting One Router to Cover a Large House

A more expensive router is not a substitute for multiple correctly positioned access points.

One device may struggle in a property with:

Several floors
Thick stone or brick walls
Long extensions
Converted lofts
Reinforced concrete
A garden office
Multiple wings
Large floor area

Wi-Fi power levels are regulated, and client devices such as phones have relatively small antennas. A powerful router may reach the phone while the phone cannot transmit reliably back to the router.

Better approach

Use additional access points or a mesh system.

Google recommends placing mesh points between the main router and the area requiring coverage, generally no more than two rooms away from another point, and keeping them in open areas.

Ethernet backhaul between access points provides the most reliable performance.

Mistake 13: Putting a Mesh Node in the Dead Zone

A mesh node cannot repeat a strong connection when it receives only a weak one.

People often place a node directly in the room with poor Wi-Fi. It may display a stronger signal to local devices, but its connection back to the main router remains slow or unreliable.

This can produce a full Wi-Fi icon without good internet performance.

Better approach

Place the node roughly halfway between:

The main router
The area with poor coverage

The node needs a strong upstream connection as well as proximity to the target room.

Use the mesh system’s app to check connection quality.

When possible, connect the node by Ethernet.

Mistake 14: Placing Mesh Nodes Too Close Together

Adding more access points does not always improve the network.

Nodes placed too close together can create:

Excessive overlap
Unnecessary interference
Poor roaming choices
Devices remaining connected to the wrong node
More wireless backhaul traffic

Better approach

Space the nodes so their coverage overlaps enough for roaming without placing several devices in the same small area.

Follow the manufacturer’s placement guidance and test performance rather than signal bars alone.

A wireless survey is worthwhile for larger homes and businesses.

Mistake 15: Placing Mesh Nodes Too Far Apart

The opposite problem is equally common.

When nodes are separated by several thick walls, the wireless backhaul may use a slow connection or repeatedly disconnect.

The local device may show a strong signal to its nearest node while the node itself has a poor route to the rest of the network.

Better approach

Move the node closer to the previous point.

Google’s guidance suggests keeping points no more than approximately two rooms apart and positioning them in open areas.

For difficult properties, install Ethernet backhaul rather than adding more wireless hops.

Mistake 16: Putting the Router Near Thick Structural Walls

Not all walls affect Wi-Fi equally.

Signal loss is often greater through:

Reinforced concrete
Thick stone
Dense brick
Foil-backed plasterboard
Metal studs
Insulated exterior walls
Chimney breasts

The route through a wall also matters. Passing diagonally through a thick wall creates a longer path through the material than crossing it directly.

Better approach

Place the access point where signals can travel through doorways, halls and thinner internal walls.

In stone or concrete properties, use several wired access points rather than attempting to force one signal through the entire building.

Mistake 17: Ignoring the Difference Between Frequency Bands

Modern routers commonly use:

2.4 GHz
5 GHz
6 GHz on compatible Wi-Fi 6E and Wi-Fi 7 equipment

These bands behave differently.

2.4 GHz

Usually provides greater range and better penetration through walls, but offers lower speeds and faces more interference.

5 GHz

Usually provides higher speeds and more capacity, but its range through obstacles is shorter.

6 GHz

Can provide cleaner spectrum and very high short-range performance, but is more easily weakened by walls and distance.

A phone close to the router may perform extremely well on 6 GHz while a device upstairs cannot see that band at all.

Better approach

Position access points close to areas that need high-speed 5 GHz or 6 GHz coverage.

Do not expect one 6 GHz radio to serve an entire thick-walled property.

Use 2.4 GHz for compatible low-bandwidth devices requiring greater reach, and wired access points for high-performance areas.

Mistake 18: Pointing Every External Antenna the Same Way

Some routers have adjustable external antennas.

The signal is generally strongest around the sides of a typical dipole antenna rather than directly from its tip. Client-device orientation also varies.

Ofcom suggests pointing multiple antennas in different directions, such as vertically and horizontally, to improve coverage across differently oriented devices and spaces.

Better approach

Begin with:

One or more antennas vertical
Another at an angle or horizontal where the manufacturer recommends it

Do not repeatedly change antenna positions without testing.

Internal-antenna routers are designed around their normal upright installation orientation and should generally not be placed on their side unless supported by the manufacturer.

Mistake 19: Covering the Router With Decorations

Routers are sometimes hidden behind:

Books
Picture frames
Plants
Fabric covers
Decorative boxes
Seasonal decorations

These objects obstruct the radio signal and may restrict airflow.

Plants can be particularly problematic because both the soil and water content can affect the path.

Better approach

Keep clear space around the router.

Do not cover its ventilation openings.

When appearance matters, use an access point designed for discreet ceiling or wall installation rather than concealing a conventional router.

Mistake 20: Stacking Equipment on Top of It

Placing a modem, external drive, television box or games console directly on the router can:

Block ventilation
Trap heat
Introduce electrical interference
Obstruct antennas
Place metal directly in the signal path

Better approach

Leave space between network devices.

Use a ventilated shelf or equipment rack.

Keep power supplies and cable bundles organised rather than surrounding the router.

Mistake 21: Locating It Near a Window

A router beside a window may provide excellent Wi-Fi in the garden while wasting signal outside the property.

Windows may also contain:

Metallic coatings
Reinforced frames
Energy-efficient films

These can influence how the signal travels.

Better approach

Place the router further inside the property unless outdoor coverage is a deliberate requirement.

For garden coverage, install a suitable outdoor-rated access point rather than relying on an indoor router aimed through glass.

Mistake 22: Putting It Next to the Cordless Phone Base

Traditional cordless-phone systems and other wireless household equipment may use nearby frequencies.

Interference may become noticeable during calls or when devices are positioned very close together.

Ofcom specifically recommends separating routers from cordless phones and other wireless equipment.

Better approach

Keep several feet of distance between the router and:

Cordless-phone base stations
Baby monitors
Wireless cameras
Wireless audio transmitters
Other routers

Test again after temporarily switching nearby equipment off.

Mistake 23: Installing Several Routers Beside Each Other

Homes and small offices sometimes contain:

The provider’s router
A separate gaming router
A mesh router
A Wi-Fi extender
A smart-home hub providing Wi-Fi

When all of them broadcast beside one another, they compete for the same radio spectrum.

They may also create multiple networks, double NAT and confusing roaming behaviour.

Better approach

Decide which system will provide Wi-Fi.

Disable unnecessary wireless radios or configure the provider’s equipment in modem or bridge mode where supported.

Do not change operating modes without understanding how your broadband, telephone service and firewall are configured.

Mistake 24: Positioning an Extender Where the Signal Has Already Failed

A Wi-Fi extender needs a usable connection to the original router.

Installing it in the dead zone produces a weak rebroadcast connection.

Better approach

Position the extender where the original Wi-Fi remains reasonably strong, often around halfway towards the problem area.

For better speed and reliability, replace wireless extenders with wired access points or a well-designed mesh system.

Mistake 25: Expecting Signal Bars to Measure Speed

A device can show full signal while still providing poor performance.

Signal bars do not reveal:

Interference
Channel congestion
Packet loss
Backhaul quality
Broadband congestion
Router processing limits
Latency
Retransmissions

A mesh node can provide a strong local signal while using a poor upstream connection.

Better approach

Test:

Download speed
Upload speed
Latency
Packet loss
Performance in each room
Wired speed at the router
Local network throughput where relevant

Use the same test device and server for meaningful comparisons.

Mistake 26: Testing Only Beside the Router

A speed test performed one metre from the router proves very little about whole-property coverage.

Your network needs to perform where people actually use it:

Home office
Bedrooms
Kitchen
Living room
Garden office
Meeting room

Better approach

Create a simple room-by-room test.

Record:

Download speed
Upload speed
Latency
Signal strength
Connection band
Dropouts
Time of day

Move the router and repeat the same tests.

Mistake 27: Moving the Router Without Checking the Cables

A router in a better wireless position may perform badly if it is connected through:

A damaged Ethernet cable
An unsuitable telephone extension
A poor-quality coaxial lead
A loose fibre connection
An overloaded powerline adapter

Better approach

Use proper cabling and check that the router’s incoming connection remains stable.

Do not sharply bend fibre cables or place furniture on them.

Test the broadband connection through Ethernet before and after moving equipment.

Mistake 28: Placing It Where It Cannot Ventilate

Routers contain processors, radios and power circuitry that generate heat.

An overheated router may:

Reduce performance
Restart unexpectedly
Drop wireless connections
Become unstable under heavy load
Fail prematurely

Better approach

Place the router:

Upright as designed
In the open
Away from radiators
Away from direct sunlight
With ventilation holes clear
Without equipment stacked on top

Do not place it on soft furnishings that block lower vents.

Mistake 29: Leaving It in Direct Sunlight

A sunny windowsill can raise the router’s temperature considerably.

The problem may appear only during warm afternoons or summer months.

Better approach

Move it away from direct sunlight while retaining an open, elevated position.

When a router becomes unusually hot, check ventilation and confirm that the power adapter is correct.

Mistake 30: Assuming a New Router Will Solve Every Problem

Poor placement is only one possible cause of slow Wi-Fi.

Other causes include:

Slow broadband
Outdated router hardware
Old client devices
Channel congestion
Faulty cables
Background downloads
VPN use
Poor mesh backhaul
Router firmware problems
Weak device antennas

Better approach

Separate the broadband problem from the Wi-Fi problem.

Connect a computer to the router using Ethernet and run a speed test.

When wired speed is good but Wi-Fi is poor, investigate placement and wireless configuration.
When wired speed is also poor, contact the provider or diagnose the incoming connection.

Finding the Best Router Position

A strong starting location is:

Near the centre of the property
Elevated above floor level
In an open area
Away from corners
Away from large metal objects
Away from electrical interference
Away from heat and water
Close to the rooms with the highest usage

Ofcom’s guidance similarly recommends a central, raised position away from other electrical and wireless devices.

The perfect location is rarely identical for every property.

A Practical Placement Test

Before installing new equipment, try this simple process:

Test the broadband through Ethernet.
Record Wi-Fi speed in the main rooms.
Temporarily move the router into a more central, raised position.
Keep it away from the television and electrical equipment.
Retest the same rooms using the same device.
Note which locations remain weak.
Decide whether additional access points are required.

Use temporary long Ethernet leads for testing before paying to install permanent cabling.

When You Need an Additional Access Point

One router may not be enough when:

The property has several floors.
Walls are thick or reinforced.
The house has a long extension.
There is a detached office.
Important rooms are at opposite ends of the building.
5 GHz or 6 GHz coverage is needed everywhere.
Many people use the network simultaneously.

Place access points where the signal is needed and connect them by Ethernet whenever possible.

Why Ethernet Backhaul Matters

A mesh node with wireless backhaul uses Wi-Fi both to communicate with devices and to reach the main router.

That shared wireless path can reduce capacity and become unreliable through walls.

Ethernet backhaul provides:

More consistent speed
Lower latency
Greater stability
Better node placement
Less dependence on wireless hops

A well-placed Wi-Fi 6 access point connected by Ethernet may outperform a newer wireless mesh node placed badly.

A Sensible Placement for a Two-Storey House

A typical arrangement could use:

Broadband modem or provider router near the entry point
Ethernet to a central ground-floor access point
A second wired access point near the upstairs landing
Wired connections to televisions, consoles and desktops
A separate wired or fibre link to a garden office

This is usually more reliable than trying to make one router cover every floor and outbuilding.

A Sensible Placement for a Flat

A single router may be sufficient when it is:

Centrally located
Raised
Clear of furniture
Away from neighbouring electrical equipment
Not hidden in a utility cupboard

In a flat, neighbouring networks may create significant congestion. Placement helps, but channel selection and modern Wi-Fi equipment may also be required.

A Sensible Placement for a Business

Business Wi-Fi should not depend on a single consumer router in the manager’s office.

A professional design may include:

Multiple ceiling-mounted access points
Ethernet backhaul
Planned channel allocation
Centralised management
Separate staff and guest networks
Capacity calculations
Roaming optimisation
Coverage surveys
Secure authentication

The goal is not simply to display a strong signal. It is to provide consistent capacity where people work.

Router Placement Checklist

Before blaming your internet package, check that the router is:

Central
Elevated
In the open
Away from metal
Away from water
Away from microwaves and cordless phones
Away from direct heat and sunlight
Not behind a television
Not inside a sealed cupboard
Not surrounded by cables and power supplies
Properly ventilated
Supported by additional access points where necessary

Small Moves Can Produce Large Improvements

You may not need a faster broadband package or a more expensive router.

Moving the existing router from the floor to a shelf, out of a cupboard or away from the television can improve performance immediately.

For larger or difficult properties, the answer is rarely one oversized router. A network of properly positioned, wired access points provides better coverage, reliability and capacity.

Router placement is free to change, easy to test and should always be investigated before purchasing new equipment.
