Experience next-generation 802.11acWi-Fi everywhere
The RP-AC52 wireless range extender has powerful internal MIMO antennas that help to eliminate signal dead zones and improve the coverage of any existing wireless router. It works as a repeater, which means it can extend wireless networking to every corner of the home — even to those difficult, hard-to-reach spots. This ensures reliable high-speed internet coverage everywhere for devices such as notebooks, tablets, smartphones, game consoles and smart TVs. RP-AC52 lets you enjoy lag-free gaming and HD multimedia streaming throughout the home.
Dual-band concurrent range extender
The RP-AC52 gets you true dual-band networking even if you’re on an older single-band router. Double your wireless performance with up to 733 Mbps bandwidth in 2.4 GHz and 5 GHz simultaneously! 2.4 GHz handles daily tasks like web browsing and social networking, while 5 GHz is great for HD video streaming and online gaming.
2.4 GHz and 5 GHz signal strength indicators
An LED signal-strength meter on the front of the RP-AC52 wireless range extender shows at a glance the strength of both the 2.4 GHz and 5 GHz signals.We recommend placing the RP-AC52 between the router and the area where you want to extend wireless coverage. The RP-AC52 works best when it is receiving a strong wireless signal from the router, and you can check this using the signal strength indicator on the front panel of the RP-AC52. This shows the signal strength for both frequency bands — the longer the illuminated band, the stronger the signal. Position the RP-AC52 so that it is as far away from the router as possible but still showing a strong signal level.
One-press setup and worry-free connectivity
RP-AC52 wireless range extender installation doesn’t require a CD or even mouse and keyboard. One press of the WPS button and setup is complete. Optimized performance is assured, so internet experiences are seamless and smooth. For detailed management, you can simply connect the RP-AC52 to a PC via Ethernet cable and go to the configuration page directly, or quickly set it up from tablet or smartphone wirelessly, with no disc or app needed.
