Asus DSL-N55U Annex A, Dual-Band Wireless-N600 Gigabit ADSL Modem Router

As the first ASUS N600 simultaneous dual-band Wi-Fi ADSL router, the DSL-N55U provides a stylish design, sophisticated features, and easy setup alongside supreme wireless and wired networking for the home.

Two USB 2.0 ports allow the DSL-N55U to share 3G/4G dongle signal; to share printing and scanning functions on a network, and operate as high-speed NAS (Network Attached Storage) when an external storage device is connected. It can act as a media server and home entertainment center. Any device, such as a PS3, iPhone, or Eee Pad can directly stream music and video wirelessly through the DSL-N55U.

For wired networking, four Gigabit Ethernet ports provide excellent capacity. Support for up to 300,000 data sessions means the DSL-N55U has around 20 times the networking capacity of other home routers. Data transmission stays fast even when the router is under heavy load, and easy-to-use QoS settings assure that important traffic — VoIP calls or online gaming — isn’t adversely affected by large file downloads.

Two Devices in One – ADSL Modem and Wi-Fi Router

Designed with the latest in networking technology, the DSL-N55U has two Independent CPUs for its ADSL modem and Wi-Fi router modes, which deliver exceptionally fast wired and wireless connectivity. It comes with a powerful detachable Wi-Fi antenna to further extend wireless range.

Dual-Band Connectivity for Lag-Free Entertainment

Double your total wireless bandwidth and reduce Wi-Fi interference with the DSL-N55U’s simultaneous 2.4GHz and 5GHz bands at a combined speed of up to 600Mbps. Basic internet processes like web browsing or file downloads run under the 2.4GHz band, while simultaneous streaming of HD content occurs in the super-fast 5GHz band, always ensuring optimized speeds and allowing a smooth and buffer-free experience.

Optimized and Reliable Wireless Coverage via Ai Radar

ASUS Ai Radar intelligently strengthens connections to wireless devices. With high-powered amplification, it provides stronger signals in any direction with better coverage to improve data throughput.

Dual Purpose: 3G/4G and WAN

Get online using your modem or via a 3G/4G USB dongle – the choice is yours. With 3G/4G failover function, you get a backup plan should DSL fail to connect.

Two Multi-Functional Built-In USB ports

Featuring connectivity to devices, FTPs, Samba, UPnP AV servers, the DSL-N55U makes sharing and networking easier with two built-in USB ports. Download HTTP, FTP, and P2P files to a router-connected USB storage device all day, even without a PC. Additionally, the twin USB ports allow for networked printer and file server connections, so you perform multiple tasks at once.
