I have seen this problem with ethernet cards I have set up before, although
I don't think I have ever used this card in particular.

With the cards I have used, there is a jumper or switch to specify which
connection you want to make (either direct into thinnet or using a drop
cable and tranceiver).  Check your card's manual to see if it has such a
switch/jumper and then check the jumper setting on the board.
