ASUS RT-AC66U Review

Our ASUS RT-AC66U review will present you why this router is at the top of its class. The router serves many other purposes than just the fast internet speed. It has twin USB ports that can connect to file, DLNA, and printer servers.

The router technology amplifies transmissions to provide a larger range of coverage than any other router out there. The wide range of applications make this router good for businesses, but it is more convenient to have in your home.

The router’s latest update, version, brings its latest firmware on board. The previous firmware had problems that were later fixed. The update contains a new cloud-based storage system for anyone wishing to access their storage remotely.

The RT-AC66U has a sleek casing that fits almost anywhere. It has detachable external antennas that stick up from its back. The router can pretty much be placed anywhere, even in a vertical position if it needs to be.

Overall, the router looks heavy duty and will gain the respect of your friends. The router has four LAN ports and one WAN port to connect to an internet source. These ports are all Gigabit Ethernet, and therefore, provide very fast internet.

The router comes with a CD of software that walks you through every step of installing the router, so you should have relative ease when trying to get it hooked up. If you are familiar with routers you do not have to use the CD to install it.

The router has a web interface that is easy to use. Through the web interface, you can add guest networks, rerun the initial set-up wizard (if you ever have to reset your router).

The interface has a general items section. This section offers a Network Map where you can view your devices currently connected to the internet.

From the Network Map, you can block a device or set-up a network storage system for that device by clicking on the device from the map. Sometimes there can be a lag when registering items.

The general items section also has a parental control feature, a traffic manager, and a way to manage the router’s USB ports.

There is also a section for advanced settings on the web interface for anyone who is tech-savvy enough to customize these settings.

In the advanced settings, for example, you can create a virtual private network for remote users. This would be great for accessing private files that in a security-sensitive company.

  • Fast and simple setup.
  • Friendly user interface.
  • Wide range.
  • Not a great design.
  • Lacks true Cloud platform of D-Link/Linksys.
  • No USB 3.0 ports.

The two USB ports that I mentioned were located on the back of the router have many functions. They have been used to connect to external data, printers, and a USB dongle that will turn the router into a mobile hotspot.

Another unique feature of this router is the Wi-Fi Protected Setup button, which starts a two-minute window to allow other people to enter the wireless network (with your permission).
