You can connect wires to the router via the Gigabit Ethernet ports for fast and reliable Internet performance. Also, there’s a download master for wireless data storage and access to the router-connected USB storage devices.

File Sharing, printer sharing, and 3G sharing through the two USB ports add more options to the device.

On the whole, you have four LAN Ports – 4 x 10/100/1000M and one WAN Ports – 1 x 10/100/1000M.

Frequently Asked Questions

1. Which should I choose between the RT-N66U and RT-N66R?

While the choice of router is up to the user, we can state that these two devices are reliable and will offer a solid and impressive performance in most cases.

You’re always going to choose either depending on the kind of task you need it for, and both models offer 900 Mbps over a good range and strong signals that should be good enough for less demanding internet activities.

In addition to that, the RT-N66U has a slightly higher cost and we lean towards it if we have to make a decision. The extra ports on the two indicate their support for wired connections, including a USB port for file sharing and data transmission.

The Gigabit ports will let you connect to a wired network, while the three antennas on either router will increase signal and coverage.


These two routers mean business with identical features and excellent specifications. You can enjoy a host of features to keep you busy online. That’s because they both have the range, speed, and coverage to help you play games, surf the net, and do much more.

The fact is that the RT-N66U is Asus’ first N900 router and is the feature-rich follow-up to the highly popular RT-N56U. It also has a cloud-enabled system.

However, it’s our opinion that there’s very little to tell them apart. Down from the frequency band, data rate, and ports, they sport the same features and offer similar performance. But we find ourselves liking the consistency of the RT-N66U model, and we think this makes for a slight advantage over its counterpart.
