Head to head
For home Wi-Fi, “booster” and “extender” often describe the same repeater-style device. Choose based on the exact setup: a separate extender for a coverage gap, or a wired access point or mesh system for broader whole-home coverage.

The verdict
TP-Link lists Wi-Fi 6, a Gigabit Ethernet port and range-extender/access-point modes.
NETGEAR lists dual-band Wi-Fi 5 and a 10/100 Mbps Fast Ethernet port.
The RE715X page lists EasyMesh compatibility, though it requires a compatible ecosystem; a multi-node mesh plan may fit better than a single device.

Common questions
In many home-network listings, “booster” and “extender” refer to a device that repeats or extends an existing Wi-Fi connection. Check the actual operating modes rather than relying on the label.
If both terms refer to a repeater, neither is inherently better. Compare Wi-Fi standard, Ethernet, mesh compatibility and setup method, then match these to your router and coverage problem.
It does not increase the speed supplied by your internet plan. A well-placed extender can improve the connection in a weak area, but the relay link may have less capacity than a direct router connection.
A single extender can address one nearby dead zone. A mesh system is often easier to coordinate across multiple coverage areas, while wired access points can provide a direct backhaul where Ethernet is available.
Place it between the router and the target area, at a point where it still receives a dependable signal. A location inside the dead zone is usually too far from the router to relay reliably.
