Do more with Dual Band technology

Use the 2.4 GHz band for everyday tasks, while leaving the high-speed 5 GHz AC band free for HD video streaming, online gaming and large file transfers. With fewer devices using the high-speed 5 GHz band, there's less interference and congestion, giving you better performance and a lag-free wireless experience.
