I' m trying to directly connect two computers using a LAN cable. The network connections box keeps saying " A network cable is unplugged" even though i have installed the drivers for my network card which is :

Realtek RTL8139/810x Family Fast Ethernet NIC
Dhcp Server: none responded
Physical Address: 00:40:F4:6C:F9:6F

Networking Dns Servers: 61.88.88.88
125.168.126.6

can someone please help me?

    You'll need a crossover cable to directly connect two PCs.

    Yeah, there's two different cables that'll plug into the same slot. One would be to connect multiple devices to a router/switch and the one you need would connect a pc straight to another pc.

    You must have had a crossover (null) cable. That's the only way to connect two computer directly over an ethernet cable.

    The null cables are usually marked with blue or yellow ends in my experience.

    Yea I'm seeing a lot of auto-sensing NIC cards these days. This one and a half year old T-Pad has one...crossover or not, it just adjusts so laptopbox might have a different problem.

    But, "network cable unplugged" is the error it would give if you had the wrong cable. So, if it worked before but not now, I wonder if after installing a new driver, there is some setting in the driver that turns auto-sensing on or off. Might also be called "MDI/MDX" or something like that. If you don't find a setting, you could try the cross over on the chance that the new driver just isn't figuring things out like it did before the new driver.

    Gigabit cards automatically sense and switch.

    Thanks Gray. The card on this this lappy that always detects is a 1000.

    I believe simple way will be to use a crossover connection with rj45 pin.
    and then do a simple network

    on my dell i have two places where i can put in my LAN cable. ONe is realtek rtl8139d and the other is the onboard network slot which is attaced to the motherboard. In network connections it only shows the realtek card and not the onboard one....

    laptopbox,

    In your first post we got the impression you were just trying to connect two computers. But I also see a couple of DNS servers listed and in another post you mention that this configuration used to share the internet. So, what's the whole network here? Is it just two computers or are you using Internet Connection Sharing to connect these two computers?

    I looked up that rtl8139d. It's a 10/100 and I didn't see anything about auto-sensing crossover. And by the way, this must be a PCMCIA card the way you talk about the on board NIC?

    Can you get to the Dell site, plug in your Service Tag and find the right driver for the onboard NIC? That might be the auto-sensing one you used to use? At any rate, with any working NIC card, you shold be able to connect directly to another computer with a crossover cable.

    go get the crossover cable, that is the cheapest, simply solution.
