Installing the client utilities from CD installs a number of other apps beyond the EZSetup program. It also installs Device Discovery, Download Master, Firmware Restoration and Photo Album Uploader. Unfortunately, these utilities are only available for Windows platforms. Linux and OSX users are restricted to the web interface.
Device Discovery is simply that - it scans the local network for any available routers and lets you open a Configuration dialogue. Download Master is a GUI interface which taps into the Download Master web dialogue. Here you can copy and paste URLs and kick off downloads, monitor existing transfers and browse the Download folder - that's right, you can download torrents or whatever files and your computer doesn't even have to be turned on. It's basically a much more convenient way of managing downloads, which minimises to the system tray when not in use.
Photo Album Uploader lets you select pictures to form the basis of a new photo album on your personal web page. We selected about 160MB of photos - initially the file transfer seemed rather slow, until we checked afterwards and discovered that the application resizes the images into appropriate web-size images AND thumbnails, and creates a full backend structure so that the photo album is live straightaway - all done on the fly. Rather impressive!
And finally, Firmware Restoration just lets you upload firmware to the device from an application interface, rather than going through the web.
