Asus RT-AC56U Rich Features Wireless AC Router

Asus RT-AC56U is one of Asus flagship products in wireless ac routers, full features router in wireless ac1200 class. How is it compared with others?

What this product does

This product reminds me with the first debut of Asus dual band router RT-N56U black Diamond, you’ve got to read more carefully knowing that the label is nearly the same – RT-AC56U. both models are designed vertically, however AC56U is wider. Unlike the other two models .i.e. AC66U and AC68U which come with external antenna, this model (AC56U) comes with internal antennas, looks elegant on your desk with metallic stand.

Based on wireless ac technology, this router becomes one of Asus products you can count on to support your high bandwidth demand applications, rich of features best in its class.

Main features

  • Based on latest wifi technology
  • solid client’s connection with AiRadar technology
  • Speeds of up to 1200Mbps
  • Gigabit interfaces and twin USB ports
  • DLNA media server
  • 3G/4G share
  • Asus AiCloud

With these main features, you have full functionality of modern home entertainment environment accessible from anywhere from the palm of your hand via your Android or iOS mobile devices.

Wifi technology

AC56U is engineered based on wireless ac1200 technology, means delivering total bandwidth up to 1200mbps – twice as fast as the speed of its predecessor RT-N56U wireless N600 (300Mbps each band).  This is the same wifi technology applied to its competitor D-link DIR-850L; and compared with Linksys EA6500 or Belkin surely it is different class (ac1750).

Asus RT-AC56U

Both Linksys 6500 and AC56U are engineered based on Beamforming antenna technology that broadcasts in all direction like Omni but focusing to the connected clients solidly to let  you roam within the house without dropping the signal. Asus AiRadar is technically beamforming technology, and most Asus routers are embedded with this tech.

D-link 850L is not designed with beamforming but the other series D-link DIR-868L and DIR-860L come with Smartbeam technology, I guess this is similar technically.

USB ports

Asus AC56U comes with twin USB ports, one port is USB 2.0 and the other one is USB 3.0 which is 10 times faster than USB 2.0. Both AC56U and EA6500 are DLNA certified media server, but D-link 850L isn’t. DLNA media server let you seamlessly connect with other DLNA compliant devices such as XBOX, Blu-Ray, Smart-TV and more devices with DLNA compliant are coming in the coming years.

However, D-link with USB port is designed with MyDlink shareport technology to let you share, sync, access anywhere from your mobile devices while on the go. You can create a private cloud and is accessible anywhere.

Asus AiDisk allows you to setup your own FTP server, connect your USB storage to the port and configure the router for AiDisk to let your storage accessible anywhere from any compatible devices. Watch this video to help you setup your storage as AiDisk cloud (courtesy by Asus and YouTube).

Linksys EA6500 on the other hand comes with smart wifi apps to let you manage your home network and connected devices remotely anywhere via your mobile devices.

3G Share

The other feature Asus AC56U with this USB port is the ability to share the 3G/4G network; you can connect the USB dongle to the router and share the cellular network with other wifi devices. This is the added value for all of high end Asus routers to help you share the cellular network when wired broadband internet is not available. You can setup the router in an impromptu situations such as in the camping ground, on the yacht, on mobile home or any outdoor activities. Its competitors D-link and Linksys do not support 3G share.

Guest network

All the three routers support guest network. But Asus is different, you can create up to three separate networks with different security settings (including password, intranet access, time schedule) each band for total up to six separate networks. Do you really require up to six separate networks for home environment? In some cases probably you do. You can enforce strict rules to your kids with time schedule in accessing the net.
