Product Overview

Thank you for choosing the Linksys by Cisco Simultaneous Dual-Band Wireless-N Router. The Router lets you access the Internet via a wireless connection or through one of its four switched ports. You can also use the Router to share resources, such as computers.

For more wireless bandwidth, the Router can create two simultaneous yet separate Wireless-N networks, one using the 5 GHz band and one using the 2.4 GHz band. For example, use the Wireless-N 2.4 GHz network to surf, e-mail, and print while keeping the less crowded, Wireless-N 5 GHz network free for time‑sensitive traffic like music, gaming, and high‑definition video. For more information, refer to Simultaneous Networks, page 10.
