Right.  I'm sleeping.  Yes, of course it's the same thing.  I tend to
use the terms "BNC", "coax", or "RG58" for this, and "10-Base T" for
UTP.  Thus the confusion.

No, that's fine, it's my misunderstanding.

I still don't see why you need wire cutters.  If this is coax, the two
most likely causes are:

1.  Somebody tripped over a cable somewhere and split the network into
    two non-functional halves.
2.  Somebody removed a terminator.

See if the other machines on the net work first.  You may have a fair
amount of debugging ahead of you.
