ASUS AiRadar enhances the Wi-Fi stability and improves coverage up to 150%*. Most importantly, the universal beamforming not only works on 802.11ac clients, but also 802.11a/b/g/n clients. Equipped with powerful hardware NAT acceleration and built-in Gigabit Ethernet, the DSL-AC55U gives you full Gigabit internet performance, with a WAN-to-LAN throughput performance of over 900 Mbps.
USB 2.0 port allows the DSL-AC55U to share printer and scanner over a network, and it can also operate as high-speed NAS (Network Attached Storage) device when external storage is connected.
The easy-to-use ASUSWRT graphical user interface unlocks the power of DSL-AC55U giving robust control to optimize your network for you. 30-second setup and easy traffic management means even network newbies can enjoy its sophisticated features, while power users will love its IPv6 support, multiple wireless SSIDs and encrypted VPN access.

Enhanced signal range and stability
ASUS AiRadar intelligently improves wireless connections by using exclusive ASUS RF fine-tuning. This ensures extended coverage, increases dynamic data speed, and enhances stability.

Total flexibility with DSL, Ethernet or 3G/4G LTE Internet connections
DSL-AC55U has multiple ways to connect to the Internet, with a choice of DSL, Ethernet or 3G/4G LTE*. You can use DSL-AC55U as a DSL modem Wi-Fi router or a standalone Wi-Fi router according to your needs. And with the ability to switch instantly between connections if one fails (and switch back again when it's fixed) or combine multiple connections for more bandwidth, it's perfect for reliable, always-on internet connectivity. *Requires compatible USB dongle

Gigabit Internet browsing with hardware NAT
Equipped with a powerful hardware NAT acceleration engine and built-in Gigabit Ethernet, the DSL-AC55U gives you full Gigabit performance. Its WAN-to-LAN throughput performance is over 900 Mbps, which is more than 4.5 times that of traditional software-based NAT Gigabit routers. This reduces the possibility of bottlenecks on fast internet connections.

Add external storage, printers, and other devices to your network
Make DSL-AC55U your media and device center. With built-in two USB ports, connect external storage drives, printers, scanners and many other USB-enabled devices to share with your networked PCs. Having your devices networked, lets you access them easier than ever before.

Robust control and optimization with DSL ASUSWRT
With the DSL-ASUSWRT dashboard UI, setup, monitor, and control network applications all in one intuitive area. The whole-new dashboard interface lets you manage all clients and settings via a single graphical interface, and provides 1-click updates.

ASUS AiCloud – 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.

Download and stream anywhere
Download Master and enhanced media server let you download and play multimedia files stored on router-attached USB storage on a wide range of compatible devices such as PC, pad, PS4, Xbox, and smart TV. Download Master can also download files while your PC is turned off, and allows you to manage and monitor download status remotely.

Better online multitasking at up to 300,000 sessions
Massive online multitasking at up 300,000 concurrent data sessions gives you 20 times the capacity of mainstream routers, allowing for great performance with no slowdown even during heavy traffic sessions. Multiple downloads occur at the same time to create a smoother user experience. More data sessions translate into quicker and buffer-less HD streaming plus lag-free online gaming even while you download content, so you can do more without compromising your online lifestyle.

VPN server and client for encrypted remote connection
With the virtual private network (VPN) server and VPN client, you can access your home network remotely or surf the internet with encryption, no need for paid VPN services or a dedicated VPN server.
