The TP-Link Wi-Fi Range Extender with AC Passthrough uses Wireless N technology and 2 external antennas to expand your home’s existing Wi-Fi and minimize coverage “dead zones.” 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.
