The problem

Why Perth homes get

WiFi dead zones

Here’s why WiFi dead zones Perth homeowners deal with are so common — and so fixable.

It’s not your imagination, and it’s not a faulty router. Perth homes are genuinely a difficult environment for WiFi, for a few specific reasons.

01

Double brick construction

Most established Perth homes are built from double brick — one of the most WiFi-hostile building materials there is. A single wall can cut signal strength by up to 50%; by the second or third wall, the signal is often gone entirely.

02

Big floor plans

Perth homes are among the largest in the world by floor area. A router sitting next to the NBN box in the study was never going to reach a 300–500m² home on its own.

03

Alfresco and outdoor living

Outdoor entertaining is core to how Perth families use their homes, and it’s almost always outside a standard router’s realistic range.

04

Two-storey layouts

Additional floors and ceiling joists absorb and reflect WiFi signal in ways that are hard to predict without actually testing it in the home.

05

Too many devices, one router

The average Perth household now has 15–20 connected devices — phones, laptops, smart TVs, cameras, speakers — all competing for bandwidth from a single access point.

06

One fix, done properly

None of these are solved by buying a more expensive router. They’re solved by fixing the coverage problem itself — that’s what we do on every job.

Quick fixes

Why the “quick fixes”

don’t work

Before calling us, most people try one of two things — and both tend to make the problem worse, not better.

Quick fix #1

A more expensive router

A faster router still only has one antenna in one spot in the house. If the problem is coverage, not speed, a better router doesn’t fix it.

Quick fix #2

A cheap WiFi extender

Extenders create a second, separate WiFi network that your devices don’t automatically switch between — so you’re manually reconnecting as you move through the house. Worse, they typically halve your speed. You end up with two weak networks instead of one strong one.

What we actually do

What we

actually do

The actual fix is coverage design, not more power in one spot — which is exactly what a properly installed mesh WiFi system does. Read our full eero mesh comparison →

Every job starts with a proper diagnosis, not a guess.

01

Site assessment

We look at your floor plan, wall construction, NBN connection point and where WiFi dead zones Perth homes typically hide — not just where you’d assume.

02

The right hardware for your home

For most Perth homes, that means a mesh WiFi system. We supply and install eero, which we rate highest for Perth conditions after testing the major brands — read why in our full comparison — but the fix is designed around your home, not a product we’re trying to sell you.

03

Placement that’s actually tested

Where each unit goes changes performance more than which brand you buy. We place and test as we go, not from a generic floor-plan guess.

04

Wired backhaul where possible

Running ethernet between even one or two nodes makes a bigger difference than almost any other single upgrade — and it’s the step most DIY installs skip.

05

Full device migration

Every phone, laptop, TV and smart home device reconnected before we leave — you’re not left to sort it out yourself.

We’ll talk through where your WiFi is dropping out and what it’ll actually take to fix it, before recommending anything.

FAQ

WiFi dead zones Perth:

your questions answered

How do I know if it’s a dead zone problem or an NBN/internet plan problem?

If speed tests are fine near the router but drop off or disappear in other rooms, it’s a coverage problem, not a plan problem. If speeds are slow everywhere, including right next to the router, that’s more likely your NBN connection or plan — we’ll tell you honestly which one it is on the phone assessment, before recommending anything.

Usually not on its own — a stronger router still broadcasts from one point in the house. If the issue is a dead zone in another room, coverage design (multiple access points working together) fixes it; router speed doesn’t.

Depends on the home. Some dead zones need one additional node; larger or multi-storey homes usually need a proper mesh setup. We’ll tell you honestly what’s needed on the assessment call — not oversell a bigger system than your home requires.

Most dead zone jobs are same-day, including assessment, hardware if needed, and installation, depending on your suburb and the day you call.

Yes — outdoor coverage is one of the most common reasons Perth homeowners call us, and it’s a standard part of what we assess and fix.

The two biggest causes in Perth are double-brick construction and large floor plans. Double brick absorbs and reflects WiFi signal far more than the timber-frame homes common in other states, and Perth’s big blocks mean rooms sit further from the router than a standard single router was ever designed to cover.
