The TP-Link RE450 is a high-performance, wall-plug style dual-band wireless signal repeater designed to eliminate Wi-Fi "dead zones" in large residential or office spaces. It connects to an existing router wirelessly to amplify and extend the primary network signal coverage. Additionally, it integrates TP-Link OneMesh™ technology, creating a seamless mesh network when paired with a compatible router so your devices stay connected to a single network name without dropping while moving from room to room.
