On the front, the router has the usual array of LEDs that show the statuses of the ports on the back, the connection to the Internet, the USB ports, and the wireless networks. These lights are very helpful in case you want to glance at them to check on the router's condition. However, if you're bothered by them, you can turn them off via a button on the back of the router. This is really a nice design touch that helps make the router bedroom-friendly.
Also on the back, the router has four LAN ports for wired clients and one WAN port to connect to an Internet source, such as a broadband modem. All of these ports are Gigabit Ethernet, which is a must for a fast local network with superfast Internet connection. In addition to being a router, the RT-AC68AU can be used as an access point or a media bridge (you can choose among these roles via its Web interface, in Wireless section under Advanced Settings), and when it's not working as a router, the WAN port can also be used as another LAN port.
On the side, the router has a Wi-Fi on-off button and the Wi-Fi Protected Setup (WPS) button, which starts a 2-minute window in which other WPS-enabled clients can enter the wireless network. By default, the WPS function is disabled and can be turned on via the router's Web interface, also in the Wireless section.
