Ethernet Card problems in Win XP
(Click here to view the original thread with full colors/images)

HI, and thanks for helping me out. XP keeps telling me that my network cable is unplugged, when everything is set up fine. I installed two cards, a D-Link DFE-530txs and a card that is RTL8139 compatible. With both cards there was the same error from windows (network cable was unplugged). XP installed the drivers automatically and the hardware profile says it's running fine. I tried to screw with my IP addresses and some other settings in the network properties but I didn't get anywhere. If any of ya'll can give me some specifics to fiddle with I'd appreciate it. I'm just looking for a few explanations of the some of the XP properties and settings so I can try new stuff. Thanks again.

Does it actually disconnect you from the internet, or does it just say "network cable unplugged" every now and then when everything's actually fine?

One good thing to check, if you haven't tried it, is locking the card speed down to 10Mbps Half-Duplex. Your card may support 100Mbps and Full Duplex, but the hub or router it is going into may not. Occasionally, auto-negotiation will fail, and can get reported back as "Network cable unplugged"
Actually had it happening to me recently, in fact. Gigabit NIC in the computer going into a 100Mbps switch. NIC decided it wanted to do Gigabit and because it wasn't getting it from the switch, it chose to sulk instead of falling back to 100Mbps. But locking it down to where it needed to be any way worked.

that can happen when a network cable dies. if you have a spare, try it, or borrow one, or worse case buy a new cable.

FIrst off thanks for responding everyone. Second, The cables are working properly, I can access the internet with another computer that has a significantly older netowrk card (old ISA slot)
Third, I tried to screw with the speed of the card both with and without a user defined IP address. Once I saw that it didn't work I had originally tried to designate an IP address under the TCP/IP in the local area connection properties, but it didn't work. ( I thought I choose a proper IP address, but I could be wrong) I don't know if I should enable a user configured IP and DNS settings or what.
The router is a D-Link DI604
Some questions:
Should I try to go back to WIN98? I have WIN XP Pro Corporate right now.
What are transmit and recieve buffers and a Tx threshold? I can change them, but are there certain combinations that are standard?
The D-Link network card:
The card uses IEEE standard 802.3 to communicate with the internet. In windows there was an option to use 802.1x standard, so I tried turning that off, but to no avail.
The cards instruction booklet says it can be used for full/half speed and duplex network at wither 10 or 100 speed. However, XP installed the driver and rightr now there is no XP driver from the manufacturer.
Again, thanks for the help.
