Stylish Concurrent Dual Band Wireless-N900 Gigabit Modem Router
The ASUS DSL-N66U
N900 modem router has up to 900Mbps in bandwidth. It is a fast modem router with support for VDSL
connections. The DSL-N66U works in 2.4GHz and 5GHz, and uses dual CPUs
for optimal computing power towards faster and more stable connections. Wired
and wireless networking each have a CPU dedicated to them, guaranteeing
improved performance. It also includes two WAN ports (Ethernet WAN and DSL WAN), allowing customers to use it as a modem router or standalone router. Equipped with powerful hardware NAT acceleration and built-in Gigabit Ethernet, the DSL-N66U gives you full Gigabit internet performance, with its WAN and LAN throughput at over 900Mbps.The ASUSWRT interface supports quick setup and simplified network management, while the DSL-N66U also includes AiCloud, the exclusive ASUS cloud computing app.
Two CPUs for fast and stable connections
The DSL-N66U offers dual CPU performance and flexibility. Its twin processors each optimize wired and wireless connections. By separating wired VDSL/ADSL and Wi-Fi networking into two compute modules with their own dedicated processing power, the DSL-N66U achieves maximum performance for both connection types with no compromises.
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.

Smart auto-detection design
makes it possible for you to go from first plugging in theDSL-N66U to setup completion in
30 seconds! Compared to the lengthy installs and hassles of other
routers, this development from ASUS offers a true wonder of ease of use, and
puts fast networking speeds within your reach quicker than ever before.

ASUSWRT - Intuitive network setup and control
Easy to use and highly intuitive, the ASUSWRT graphical interface offers complete network management. Gamers and HD media consumers get improved performance with ASUS QoS bandwidth prioritization that prevents slowdown even with other tasks in the background. One-click settings enable easy troubleshooting, plus printer, parental controls, and Download Master all ensure better network productivity and management.
Two WAN ports for DSL and Ethernet offer double the choice
The DSL-N66U has two WAN ports, allowing it to be used as a standalone router when not operating as a ADSL/VDSL router modem. You can choose which mode suits your needs, and in any scenario gain considerable savings and clutter reduction by not having to buy separate power-consuming devices. Whether for a basic home setup or a full wireless network, Ethernet WAN affords the flexibility you require.
Gigabit Internet Browsing with Hardware NAT
Equipped with a powerful hardware NAT acceleration engine and built-in Gigabit Ethernet, the DSL-N66U gives you full Gigabit performance, making its WAN to LAN throughput up to 2-5 times that of traditional software-based NAT Gigabit routers.
AiCloud - Sync. Share. Stream.
Your World on Demand
ASUS AiCloud keeps you connected to your data wherever and whenever you have an internet connection. It links your home network and online Web storage service* and lets you access it through the AiCloud mobile app on your iOS or Android smartphone or through a personalized URL in a Web browser.
