I have an Asus A7V600 motherboard with the onboard 3Com 3C940 1000 Mbps Ethernet NIC. I go to the University of Florida and when I set it to 10 Full Duplex since that is what he have here in my dorm it will only set to 10 Half thus drastically slowing down my connection. I upgraded from the 44 driver to the 46 one and I still have the problem and flashed my bios from 0012 to 0015 and still the same problem. I was wondering if anyone else had problems with this card and if so if they were able to fix it. There are quite a few people here who are currently having this problem. Thanks for any info that you can give me.
