Wi-Fi Booster Speed: Choosing for Faster Coverage

It can improve a weak local Wi-Fi connection, but it cannot exceed the speed delivered by the internet connection or overcome congestion outside your home.

The extender communicates with the router as well as the client, and a wireless relay shares airtime. Distance, interference and device limits also reduce throughput.

Not in every home. A mesh system can coordinate nodes and may offer dedicated backhaul, while performance depends on model, topology, wired links and placement.

Ethernet can provide a stable backhaul to an access point or mesh node, reducing reliance on a wireless relay. The result still depends on cable, ports and internet service.
