All are in good condition as I operate the router in a server case. Even the boxes are also in good condition as I've kept it in a enclose drawer.

Dual-band for Lag-free EntertainmentDouble your wireless performance and bandwidth with simultaneous 2.4GHz and 5GHz bands, with speeds up to 300Mbps concurrently. While basic internet applications like browsing or file downloading can occur in 2.4GHz, wireless HD content streaming takes place in the 5GHz band at the same time, so both achieve optimized speeds and you get to enjoy smooth, buffer-free HD content streaming.
Plug-n-surf and Hassle-free ManagementASUS QIS and EZ UI offer you an intuitive router setup without reading manuals. Open your browser, then the QIS wizard will guide you to quickly connect to the Internet, regardless of what OS you use. The intuitive user interface provides a graphical network map, making wireless setup, QoS and client management clear and simple.
4-Network-in-1: Provide Extra NetworksThe RT-N53 can provide 4 wireless networks over the 2.4GHz band, which provides separated connection priorities and access rights. For example, High priority and both network (private and Internet) access are perfect for managers, while middle priority and private network work great for staff, and low priority and internet access only for friends and guests. Protect computers from unauthorized access, hacking and virus attacks.
Universal Repeater - Extend your signal in the simplest wayWith ASUS Universal repeater support, you can use the RT-N53 way to repeat your wireless signal to far away locations from the central access point. Scan for the Wi-Fi signal and link to the SSID you want to repeat.
*Please take note that all repeaters, including this Universal Wireless Repeater mode, will sacrifice half of the bandwidth available from the primary router for clients wirelessly connected to the repeater. Currently, the RT-N53 only supports the 2.4GHz repeater setting.
