Hello,

It's the firewire adapter. So long as you have the appropriate driver for your Network Interface Card or Wireless Adapter Firewire has no bearing. The fact that it's coming to your attention suggests the NIC driver is not installed, so check that.

The 1394 interface was, apparently, used for networking at some point, but no longer.
