The front panel features all the power/activity LEDs for the
unit, hard drive, LAN/WAN and wireless LAN ports. The LED status
indicates what activity is occurring no LED means no connection,
steady LED shows connection, and flashing LED means activity. There
are two buttons on the front Power and Copy. Power turns on the
system and mounts the hard drive, while Copy will transfer data
from a connected USB storage device (like a hard drive or flash
drive) to the internal hard drive.
The back panel sports the AC-in jack, the Reset button (hold for
ten seconds to return to factory defaults), two USB 2.0 ports
(three ports in total), one RJ-45 WAN port, four RJ-45 LAN ports
(4-port switch), the wireless antenna jack, and the EZSetup button,
which is used to launch the EZSetup application.

Apart from the highly impressive hardware feature set, the main
attraction with the WL-700gE is its in-built operating system.
Based on a minimalist Linux build, the onboard OS is embedded into
the firmware and takes over the full capacity of the hard
drive.
At a basic level, the router functions as an UPnP NAS device. The
hard drive has a pre-defined file structure for downloads, music,
photos, videos, web files, ASUS utilities and automated USB copies.
The drive is available via UPnP once the initial router
configuration has taken place. No special software is required to
access the drive a connected client running TCP/IP, the Microsoft
Client and the File and Print Sharing protocol (the basic Windows
networking setup), will be able to connect. For Linux and OSX
users, the router uses CIFS as its default network file protocol
and it also supports NFS. In a worse-case scenario, the drives
contents are also accessible via FTP or the routers web-based
admin page.

Imagine all the porn you can download without even
switching on your laptop or PC!
