WiFi Booster: Do They Work in Real Homes?

They can improve WiFi coverage in areas that are within reach of a usable router signal. Results depend on the building, interference, router, and where the booster is placed.

Not necessarily. It may improve the connection on a device in a weak coverage area, but it does not raise your internet plan's speed or fix a slow connection reaching the router.

Place it between the router and the area with poor coverage, where it can still receive a stable signal. A spot inside the dead zone may leave the extender with too little signal to repeat well.

A signal can pass through some walls, but materials and distance affect how much signal remains. Dense construction, multiple walls, and interference can reduce performance.
