Hikvision DS-3WRE3N Wi-Fi Repeater (Range Extender)

DS-3WRE3N plugs into an outlet between the router and the weak-signal area and repeats the signal further: a far room, the second floor or a hallway gets stable Wi-Fi with no cabling. Setup takes a minute — the WPS button or a web page. Useful for Wi-Fi cameras and smart devices sitting at the edge of coverage that keep dropping off.
