I can post you one I'm not using, instead of you buying one. It's a Realtek PCI 8139 10/100 Mb/s. Let me know if you're interested. Chris

However, I have tried another NIC in the machine (a Realtek USB adaptor) and it worked normally. At that point I would suspect the hardware except that when this machine had linux loaded on it, it worked normally. The box is in a 1U case with no spare PCI slots, so I need the motherboard NIC to work for it to be useful long-term.
