Stream video, place Internet calls, and game online without lag thanks to the range extender's 300 megabits per second speed. Its built-in power socket keeps your outlet free for other uses, and an Ethernet port allows the extender to connect wired devices like smart TVs and gaming consoles to your Wi-Fi.
