The ASUS DSL-N55U utilizes a powerful tri-antenna, dual-CPU design that offers the complete benefit of ADSL modem and router features in one streamlined and easy to use device. It supports simultaneous 2.4 GHz and 5 GHz transmission at up to 600 Mbps, making it an ideal choice for power users, gamers, and consumers who stream HD media regularly. Quick and simple installation gets users online complication-free, while two USB ports afford multi-role usability as a file, media, and printer server. Two dedicated devices in one at twice the speed Equipped with two discrete CPUs, the DSL-N55U carries out both modem and router duties in wired and wireless modes. It thus saves users the space, energy requirements, and cost of maintaining a separate ADSL modem and router. With its integrated home gateway design, the tri-antenna DSL-N55U works in dual-band 2.4 GHz and 5 GHz frequencies simultaneously, giving users access to 300 Mbps per band, or a total of 600 Mbps in bandwidth. The 2.4 GHz band can be used for normal online tasks such as web browsing, email, and social networking, while the cleaner and less congested 5 GHz band remains free for intense applications such as online multiplayer gaming and HD multimedia streaming. The DSL-N55U supports up to 300,000 concurrent data sessions, similar to other high end network products from ASUS. It therefore outperforms basic modem routers by up to a factor of 20. The three antennas combine with exclusive ASUS Ai Radar signal enhancement technology, detecting local conditions and the positions of connected devices to ensure the best possible transmission quality. Ai Radar extends coverage range by overcoming obstacles and sources of interference, and results in a more reliable signal. EZ UI delivers ease of installation and use The ASUS EZ UI interface auto-detects ISP settings, so a connection can be established in seconds. Users simply follow several on-screen instructions to configure their home network, with no disc or manual required. The DSL-N55U takes out the complexity from modem and router setup, and offers users the full benefit of its features within minutes of first opening the box. ASUS plans to incorporate its ASUSWRT firmware into the DSL-N55U via a live upgrade in April, offering access to multiple SSIDs, IPv6, 3G sharing, and the Download Master web-based interface. ASUSWRT was previously incorporated into the ASUS RT-N66U. Dual USB ports enable extensive expandability With the standardized accessibility of USB, the DSL-N55U can transform instantly into a file, media, or printer server for even greater utility and multi-role value. It comes fully DLNA-compatible for seamless integration with a variety of devices, from game consoles to set top boxes. Powered USB also serves to recharge portable devices such as smartphones and tablets.
