How to Extend WiFi Range in a Large Home — Complete Guide
A single router covers about 50–80 square metres effectively. Larger homes, brick walls and multi-storey layouts all create dead zones where WiFi is too weak. Here is how to fix it properly.
A single router covers about 50–80 square metres effectively. Larger homes, brick walls and multi-storey layouts all create dead zones where WiFi is too weak. Here is how to fix it properly.
Common causes:
- Single router placed in a corner of a large home
- Brick internal walls attenuating WiFi signal
- Multi-storey layout with signal loss between floors
- NBN-supplied router designed for apartments not large homes
- Interference from neighbouring networks
Optimise router placement first
Move the router to the most central location. Avoid cupboards, behind TVs or against exterior walls. Every wall reduces signal by 30–50%.
Understand 2.4GHz vs 5GHz
Connect devices near the router to 5GHz (faster, shorter range). Devices further away should connect to 2.4GHz (slower but better range).
Add a WiFi range extender — budget option
A TP-Link RE Series extender plugs into a power outlet and rebroadcasts the signal. Note: creates a separate network name and reduces speed.
Install a mesh WiFi system — recommended
Mesh systems (TP-Link Deco, Eero, Google Nest WiFi) use multiple nodes placed around the home. Devices automatically connect to the strongest node seamlessly. Best solution for most Australian homes.
Use powerline adapters for granny flats
Powerline adapters send the network signal through existing electrical wiring. Excellent for granny flats without running cables.
Consider a wired access point for maximum performance
If you can run ethernet to a distant room, a wired WiFi access point provides full-speed WiFi without wireless backhaul loss.

Frequently asked questions
What is the best way to extend WiFi in an Australian home?
For most homes, a mesh WiFi system (TP-Link Deco, Eero or Google Nest) is best — seamless coverage, no separate networks, easy to expand.
Will a WiFi extender fix my dead zones?
It improves signal but reduces overall speed by 30–50% due to wireless backhaul. Mesh systems are a better solution.
How many mesh nodes do I need?
For a standard 4-bedroom Australian home, 2–3 nodes provide full coverage. Larger homes or thick brick walls may need 3–4 nodes.
