  1. When I use the device manager and expand Network Adapters I see three devices:
    1. Realtek ... Fast Ethernet NIC
    2. Atheros ... Wireless Network Adapter
    3. 1394 Net Adapter
    (your system will be different in which are present and the brand names for the devices)

    (1) is the wired Network Interface Card / chip
    (2) is the WiFi wireless card / chip

    But what is the 1394? Can this be used for Internet access? Short answer: no.

    The 1394 is a reference to the IEEE 1394 Specification.
    This device enables support for Firewire devices, which compete against USB devices.
    Typically external HDs come with both USB and 1394 Firewire ports.

    Speed: 800MB Max, 400MB/s typical, 200MB nominal on XP

    File Sharing: MS KB310433 cites:
    Transmission Control Protocol/Internet Protocol (TCP/IP) over IEEE 1394. This feature makes it very easy to share a single Internet connection when you connect one computer to the Internet and then connect more computers to the first computer. The Windows XP built-in Internet Connection Sharing feature provides the necessary software support. IPX is NOT supported

    Unless you have a Firewire device, you can ignore the device and even disable it
    to save power (on laptops) and clarify the fact that this device is of no concern ON YOUR system.

    I get enough inquiries about firewire to ethernet adapters (mostly from Mac users for some reason) that I suspect some enterprising manufacturer (probably in Asia) will eventually come out with one, much like they did for USB to Ethernet adapters a while ago.
