AC1200 dual-band extender with smart plug

The TP-Link RE370K extends an existing Wi-Fi network across 2.4 GHz and 5 GHz bands, delivering combined wireless rates up to 1.2 Gbps. It is suited for households that need stronger coverage in distant rooms without replacing their current router. The integrated smart plug lets users switch connected appliances on or off from a phone.

Compact wall-plug design with Gigabit Ethernet

The unit plugs directly into a mains socket and measures 4.92 x 2.76 x 2.52 inches, weighing .53 lb. Five status LEDs show power, both radio bands, smart-plug state and overall link health. A single Gigabit Ethernet port allows a wired device such as a smart TV or game console to join the network through the wireless bridge.

Kasa app control and quick setup included

The package supplies the extender, a quick setup guide and an RJ45 cable. Through the Kasa app on Android 4.2+ or iOS 9+ devices, owners can manage the smart plug remotely, toggle LEDs and configure the extender without a computer. The hardware operates from 0 to 40 °C and stores safely down to -40 °C.

Questions about this item

What Wi-Fi standards does the RE370K support and what is the maximum combined data rate?

The RE370K supports IEEE 802.11ac, n, g, b, and a standards on dual-band 2.4 GHz and 5.0 GHz, delivering a combined wireless data rate of up to 1.2 Gbps.

What are the exact dimensions and weight of the RE370K for wall-outlet placement?

The unit measures 4.92 inches by 2.76 inches by 2.52 inches and weighs 0.53 lb, so it plugs directly into a standard AC outlet without blocking the second socket.

How is the RE370K initially configured and which step do users often miss?

Plug it in, connect a phone to its default Wi-Fi, then open the Kasa app to follow the setup wizard; the step often missed is moving the extender to a location halfway between the router and the dead zone after the wizard finishes.
