I also have this card and yhis is the same thing that happened to me
when I switched from a 10mbps Hub to a 100mbps hub for my network. It
seemed to work with everthing but NFS. Considering the card, even in
100 mode, can't seem to do more than 1M/s I just stuck it back on the
10mbps hub, and regained the ability to use NFS.
