How to Choose a WiFi Extender for a 100m Range

A stated range can describe ideal conditions, often without the walls and interference found indoors. The usable distance in your home will vary with building materials, placement, bands and the source router.

It is a coverage claim whose practical meaning depends on how the manufacturer measured it. Check the product's notes and do not assume the figure guarantees a particular speed or signal through walls.

Place it where the router signal remains stable, roughly along the route to the area needing coverage. Installing it at the far edge of a dead zone leaves little signal for it to extend.

It may help in some layouts, but floor area alone is not enough to predict coverage. Multiple floors, dense walls and distant wings can call for more than one access point or a mesh arrangement.

It can improve the local WiFi connection where the router signal is weak, but it cannot raise the speed of the broadband connection itself. The repeated wireless link can also be affected by distance and congestion.
