I have an old machine, with a PCI Ethernet card, SMC1211TX instaled. The problem is, Ubuntu cannot detect the existence of this card.

lshw does not show the card, and of course ifconfig shows nothing too.

Anybody can help?

Just fyi, in fact I have set up a USB Wireless G dongle to work with my old machine, but the problem with this wireless connection is the Linux -> Windows file transfer speed cap. I have no idea how to solve that.
