Better WiFi with AC1600 Dual Band
Dual band gives you two WiFi networks operating simultaneously in the 2.4 GHz and 5 GHz bands. Single band routers only use the 2.4 GHz band. This band is often full of interference as all your devices share that single band with your neighbors. The 5 GHz band in dual band products is typically much less crowded and has less interference. The bottom line? Dual band delivers much better WiFi.
AnyBeam WiFi beamforming at 2.4 GHz and 5 GHz focuses the wireless signal on your wireless devices to further enhance wireless performance.
Clean and Easy
Integrating the modem and router saves space, reduces wires and power cubes, and provides a single user interface.
