Getting decent WiFi in a landed house is a completely different challenge compared to a flat or condo unit. The problem is not just size, though size plays a role. It is the combination of floors, staircases, thick structural walls, and the sheer distance between the router and the furthest corners of the property. Many landed homeowners have gone through two or three routers trying to solve a problem that no single router can ever fully fix.
This article walks through the specific reasons why landed houses are difficult for wireless coverage, what the right solutions look like, and how to make sure your setup holds up as your household's device count keeps climbing.
Why Multi-Story Landed Houses Are the Hardest Properties to Cover
Most WiFi coverage advice is written with a flat floor plan in mind. Landed homes do not follow that logic. A typical Singapore terrace or semi-detached house might have three floors, a basement, a rear extension, and an attic space. The signal from a single router has to travel vertically through concrete floor slabs as well as horizontally through brick and plaster walls.
Concrete floor slabs are among the most effective materials for absorbing and scattering a WiFi signal. A router on the ground floor might give excellent coverage on that level but produce a noticeably weaker signal on the second floor directly above it, and practically nothing useful on the third. Each floor effectively creates a new coverage problem that cannot be solved by the floor below.
Add to that the fact that most routers are placed near the main door or wherever the telco installed the optical network terminal on the day the broadband was activated. That point is usually at one end of the house at ground level, which is almost always the worst possible position for a property that extends in multiple directions and upward.

What Does Not Work and Why
WiFi repeaters and range extenders are the most common first attempt at solving coverage problems in landed homes. They are inexpensive, plug into a power socket, and look like a quick fix. The problem is that a repeater rebroadcasts whatever signal it receives, at roughly half the speed of the original. By the time you are on the third floor using a repeater that is connected to a second repeater on the second floor, the speed you actually experience is a fraction of your broadband plan.
Mesh WiFi systems are a step up from repeaters because they are designed to work together as a single network. Wireless mesh systems still share the same core limitation though: the nodes communicate with each other over the air, which consumes bandwidth and creates latency. In a multi-floor property with thick concrete slabs between floors, the wireless backhaul between mesh nodes can be weak and inconsistent.
The honest conclusion is that wireless-only solutions are a compromise. They are better than nothing, but they are not the right foundation for a property that needs reliable, high-speed coverage across every floor and room.
The Right Solution: Wired Access Points on Every Floor
The correct approach for a multi-story landed home is a structured wired network with access points placed on each floor, each connected back to the main router via an ethernet cable. This is the same architecture used in commercial buildings and hotels, and it works for exactly the same reasons: every access point has a direct, full-speed connection to the network, so the signal on the third floor is just as strong and fast as the signal on the ground floor.
A professional home wifi service handles the planning and installation of this kind of setup. The engineer starts by assessing the property layout, identifying the best cable routes between floors, and determining where each access point should be placed for maximum coverage per floor. In most landed homes, one access point per floor is sufficient, though larger properties or those with rear extensions may need two per level.
The cables are run through existing conduit paths where possible. In properties that are being renovated, the cabling is laid before walls are sealed, which gives the cleanest result. In completed properties, cables can still be run through false ceilings, riser spaces, or surface trunking where no other path exists.

What to Expect from the Installation Process
- A site survey and floor plan review before any work begins
- Cable route planning that minimises disruption to finished walls and ceilings
- Cat-6 ethernet cables run from a central network switch to each access point location
- Access points configured on the same SSID so devices roam between floors automatically
- Speed testing on every floor after installation to confirm coverage and performance
HomeNet handles the full process from the initial assessment through to testing and handover. Their engineers have experience across Singapore's landed property types, from terraces and semi-detached homes to bungalows and cluster houses, each of which has its own structural quirks that affect how cable routes and access point positions are planned.

Planning the Network Before Renovation: The Smarter Approach
If your landed home is currently being renovated or you are planning a major upgrade, this is the ideal time to sort out the network infrastructure. When walls are open and false ceilings have not yet been installed, running ethernet cables to each floor and room is straightforward and inexpensive relative to doing the same work in a completed home.
A thorough home network setup Singapore plan at this stage would cover not just WiFi access points but also data points for wired devices in key locations, IP camera cabling for security systems, and the placement of a central network cabinet that keeps all the equipment organised and easy to manage. Getting all of this done during the renovation means the finished home has a clean, concealed network infrastructure with no visible cable runs or surface trunking.
The decisions you make during this window have a long tail. A well-cabled landed home can support 30 or more connected devices simultaneously without performance issues, handles future technology upgrades without needing major changes, and gives every room the same reliable connection quality regardless of how far it is from the router.
Key Factors That Determine How Many Access Points You Need
- Total floor area per level - larger floors may need two access points for full coverage
- Number of floors including basement and attic if used regularly
- Wall materials - thick brick or concrete between rooms requires more access points
- Number of concurrent users and devices across the household
- Whether outdoor areas like the garden, garage, or pool deck need coverage
Frequently Asked Questions
Can HomeNet install the network in a landed home that has already been renovated?
Yes. HomeNet works in both under-renovation and completed properties. In completed homes, they identify the best available cable routes through false ceilings, riser spaces, and existing conduit paths to minimise disruption. Surface trunking is used only where no concealed route is available.
How long does a full network installation take for a three-story landed home?
A three-floor terrace or semi-detached home with one access point per floor typically takes one full day for cabling and installation. Larger properties or those requiring more access points and additional data points may take two days. HomeNet confirms the timeline after the initial site assessment.
Will all devices on different floors connect to the same WiFi network name?
Yes. All access points are configured to broadcast the same network name and password. Your devices roam between floors automatically and connect to whichever access point gives the strongest signal at any given moment, without you needing to manually switch networks or notice any interruption.
