I'm running Win2k with a 10Mbps NIC and a 10/100 Mbps NIC. The 10Mbps NIC is connected to my cable modem and the 10/100 NIC goes to my LAN through an auto sensing hub. The problem is that I cannot get the 10/100 NIC to run at 100Mbps. Everything else on my network runs at 100Mbps. I've tried forcing the card from Auto to 100Mbps and even moving it to different PCI slots as well as using different 10/100 cards. This is also the case when I boot up to Win98 or Millenium. My system specs are: Celeron 400; Tyan Tsunami ATX mobo; 256Meg PC100 RAM

Same deal here mate. It's because your cable modem is running at a -10Mbps speed. Your cable modem will never ever hit 10mps let alone 100. So in essence it really doesn't matter what it says. Consider the cable modem another computer for a second. If you plugged it into an auto-sensing hub it would switch to 10mbps because it is that slow. Windows is just doing the same thing...G'luck

Have you tried setting it to 100-half duplex?

Yes, I've tried setting it to half duplex. Gerak, I contacted Tyan an they said that there should be no problem with a computer running two nic's at different speeds. Also, my network does run at 100Mbps from Server to laptop and 10Mbps from PC with two nic's to laptop or server. Really, I can see no reason that the OS would throttle down the 100Mbps capable nic to 10Mbps.

Hi, I'm running 2 NICs on my server, same setup as you have (cable modem & LAN). I used to have a 10Mb NIC attached to my cable modem and a 100/10Mb attached to a 100/10Mb D-Link switching hub. The setup was running at 100Mb without any problems, I had installed multiple systems, all vere able to run @ 100Mb (exept the cable modem NIC that was a 10Mb card). Then I even changed the cable modem NIC to a 100/10Mb, still everything was running fine (and still is). What I have noticed was when I connected a 100/10Mb Win9x machine to my LAN, it would not work at all, the hub wouldn't even light up. That made no sense, hub is 1000/10Mb, the Win9x PC was 100/10Mb NIC... still no luck. The card was installed properly, it was getting IP from the server... still, it would not even ping other PCs on the LAN. It turned out to be the HUB, there is some sort of a switch that ebables/forces 10/100 on all ports, for some NICs forcing 100Mb without forcing 10Mb first doesn't seem to work. I had to go through forcing 10Mb, then forcing 100Mb, then autosensing, then it would stay at 100Mb. This happend only to my 3Com cards, all Intel NICs had no problems with autosensing 100Mb from the beginning. Hope this will give some more options to test. Manxx

I would just like to say that I am running Win2k AS and I have two NICs installed. One is a 3COM ethernet for my cable modem running at 10Mbps and another is a D-Link 540TX running at 100Mbps and also plugged into a D-Link switch/hub. You can run multiple NICs in the same computer and at different speeds simultaneously. My system runs fine like this. I just thought that I would mention this so that you know it is possible, sorry that I can't help out any further with your specific problem.

I am trying to put 2 nics into a server to enable a vpn, but I am having problems with speed also. As soon as I put in a second card (doesnt matter what brand), and try to browse my network, everything is really really slow, even the local computer takes forever to open through the netork. Maybe that is the problem you are having too. If anyone knows what I could be doing wrong please email me. I think some of my problem is active directory.
