Why there is no single reach distance
A manufacturer’s coverage description cannot predict the result in every building. Construction materials, neighbouring networks, router position and the client device all affect the link.

How Far Can a WiFi Extender Reach in Your Home?
There is no dependable distance figure for every home. Walls, interference, router signal and extender position shape the usable coverage.
The extender must receive a usable signal
A repeater relays what it receives. Put it too far from the router and the extended network may also be weak; use the setup indicator or app to find a better point.
Walls and floors change coverage
Dense walls, foil-backed insulation and floors can attenuate radio signals. Test the route into the target room instead of relying on an open-space range claim.
Check coverage where you use devices
Walk through the rooms with a phone or laptop and note where the connection becomes unreliable. After setup, repeat the check at the same locations.
When one extender is not enough
A long or complex layout may need a wired access point or a mesh system with well-placed nodes. More repeaters do not automatically mean better performance.
Common questions
Questions before you buy
How far can a WiFi extender reach?
The usable reach varies with the building, interference, router signal and device. Treat range claims as conditions-dependent and test placement at home.
How far should an extender be from the router?
Place it far enough towards the coverage gap to help, but still where it receives a reliable router signal. Its indicator or app can guide adjustment.
Can a WiFi extender reach through walls?
Signals can pass through walls, but materials and thickness reduce strength differently. A position with fewer obstructions may work better.
Will a WiFi extender cover a garden?
It depends on the building and distance to the outdoor area. Check the signal at the intended location and use equipment rated and placed for the environment.
