Stylish Concurrent Dual Band Wireless-N900 Gigabit Modem Router
The ASUS DSL-N66U N900 modem router has up to 900Mbit/s in bandwidth. It is currently the fastest 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.
Get online in 30 seconds
Smart auto-detection design makes it possible for you to go from first plugging in the DSL-N66U to setup completion in under 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 the most extreme 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 works with ASUS routers to offer the most complete, accessible, and secure cloud platform. It's a free app for iOS and Android devices, and allows you to easily sync, share, stream, and access all your content from any location.

For the most intuitive and flexible cloud access from almost any device and location, ASUS AiCloud is your launch point.
Add external storage, printers, and other devices to your network
Routers can easily become so much more by simply adding the convenience of USB ports, which makes them into multi-role servers. Connect external storage, printers, scanners, and many other USB-enabled devices, and exponentially increase your productivity by sharing resources across your network. No queuing for tasks to complete: get more done at the same time and discover genuine router flexibility.
Optimize Your Network for You
Do you game a lot, or spend most of your time streaming videos? Whatever your planned use is, the DSL-N66U has a Quality of Service (QoS) that lets you select how much bandwidth is prioritized for virtually any task. Plus, the traffic monitor allows you to check your Web usage in a clear and graphical interface.
Separate and Secure Wi-Fi Network via Guest Network Access
The DSL-N66U supports up to three wireless networks over the 2.4 GHz band and three over the 5 GHz band, so it can protect computers from any unauthorized access, hacking and virus attacks. The parental control allows you to set up your kids' computer access times.
VPN Server Enabled
Easily set up a VPN server to surf the Web and access data--no matter where you are. Featuring MPPE encryption, your data transmission will be secure and confidential.
Powerful Online Multitasking at up to 300,000 Data Sessions
Support for a massive data pipeline of up to 300,000 data sessions means the DSL-N66U has around 20 times the networking capacity of conventional routers for exceptionally smooth performance.

Write a review for: Asus DSL-N66U Concurrent Dual-Band Wireless-N900 ADSL Router
What seems like a very good modem router on paper turned out to be a big disappointment in use. I bought my first as a returned item and when this stopped working I got another, brand new one to replace it with. Both stopped broadcasting on the lower and more used frequency, without giving any indication that it had. All lights remained on at the front. A real shame. Also the web interface froze on the new one, requiring a reset to fix. Avoid!

BT Sport users beware!
If you want to watch BT Sport via Youview then this router is definitely not for you.
I bought this router to replace my BT Infinity modem and Home Hub 3 and since the Asus has been installed I have been unable to watch BT Sport via my Youview box.
I have raised the issue with ASUS but their support is truly awful - their response times are very slow and the support staff are technically very weak.

Not there yet...
Easy to setup and the range of the 2.4ghz frequency is much better than the home hub 4 I was trying to replace.
The router settings page has so many options which include the ability for it to check and self install firmware updates so you can get a lot of control from your iPad...
Unfortunately as per end of January the router does not support Airplay - We have 2 speakers around the house which work just fine with the BT router but spent a weekend playing with the settings in the ASUS and gave up in the end...
A great kit but on paper but for its price, you would expect it to just work...
