The functionality of the device is visually described with such pictures:

So, besides the WAN/LAN/WLAN functionality proper, the router offers the opportunity to connect a network disk drive, printer or web-cam via USB, without a computer. We’ll learn more about the functionality of the router below as we will try to set it up.

What’s inside this device? First, a Broadcom BCM5364PKPB network processor with support of five “wired?ports and with RAM and ROM chips (its RAM is as large as 32 megabytes, while its ROM contains the core of a compact version of Linux, see below). Second, a wireless controller Broadcom BCM4306KFB and a Broadcom BCM2050KML transceiver. The USB section is supported by a VIA VT6212 chip. This PCI host-controller provides four USB ports, two of which can be found on the router’s rear panel and two more are pin-connectors on the router’s PCB. So, if you are skilled enough (particularly, at soldering), you can output these connectors to the outside (see this link for details) or use them inside the router’s case by putting there a USB flash drive of necessary capacity (see this link) or even a two-inch hard drive for 40 or something gigabytes via a USB-IDE adapter (an old and cheap 4200rpm model will suit all right here). There’s enough space inside the case to accommodate such a drive, and you’ll only have to add one ampere to the 5-volt line of the router.

So, here’s a list of the things added in the Deluxe version of the router:

• A USB port has replaced the parallel port, and it’s now USB version 2.0. Thus, the integrated print-server doesn’t support LPT printers anymore
• A black-and-white web-camera is now included with the router
• Support of Broadcom’s Afterburner technology is declared. This technology is claimed to increase the data-transfer rate by up to 35%.
