Wireless and wired given same interface?

[dnairb]

System -> Administration -> Network Tools -> eth0 interface -> configure gives the following alert:

The interface does not exist
Check that it is correctly typed and that it is correctly supported by your system.

I also noticed that the interface statistics on this tab shows thousands of reception errors, even though the network is active and working OK.

So I tried a few terminal commands:

sudo lshw -C network gives:

iwconfig gives:

This seems that Ubuntu has eth0 as both a wired and a wireless interface.

I have a Lan port on my box, but have disabled it in BIOS as I don't use it. I have a wireless adapter (Belkin F5D7050, version 4 using the open zd1211 driver) that worked perfectly in Gutsy and other than this problem works OK in Hardy.

Any ideas as to what is going on?

**EDIT: The above occurs on a fresh-install of Hardy, and running from the Live CD, with or without LAN enabled in BIOS
