just to be clear .. plugging the cable only will not make it recognised. the other end needs be in a router or something, ,to make a circuit.
Make sure the port is not dead...
Apart from that it should show as connected.. though you need make sure you have drivers etc before it will actually work.

Please check the bios/drivers to ensure you do not have a power saving option like GREEN Ethernet or similar.

I have once seen a green switch and green adapter not see one another(Dlink switch and I think it was an Intel lan card).

They both powered down when not detecting the other device because it powered down waiting for a signal(voltage) from the other end as well.

I HAVE THE EXACT PROBLEM YOU MENTIONED. I have a Dell with Intel Lan Card and an HP with a Dlink. I am trying to get them connected to each other directly via ethernet but both of them say that the cable is unplugged.

I just want to confirm, the computers are both connected to dlink and it works, but to each other they show unplugged?

Do you get any lights? When you connect computers to each other you most times need to give each one an ip in the same and subnet(192.168.2.1 and 192.168.2.2 ect and a subnet of 255.255.255.0. You can use other numbers as long as they work with the subnet).

If you do not get any lights, check the bios for power savings options if not the card properties in device management should have an option.

No. One computer has a Dlink network adapter and the other has an Intel network adapter. They are plugged into each other (directly with an ethernet cable) and BOTH of them say no network cable is connected. They both tell me a network cable is unplugged.

Will giving these computers an IP address mess up WIFI?

I do not know how to check the bios for power saving options and I did not see any power saving options in the card's properties in device management.

If you're trying to directly connect two computers, you need a crossover cable. A straight through cable (standard cable) only works if you connect to a hub, switch, etc. If you use a regular cable to connect two computers the transmit pins on one computer are connected to the transmit pins on the other. They need to be flipped, hence the crossover cable. It connects transmit to receive.

Most newer cards will deal with it automatically, but yes, fredweston is right, many times you do NEED a crossover cable. or just to stick any router/switch or hub in between them.

If you can get them to see one another, then you have to assign the systems an ip address because in a normal setup, DHCP will take care of it for you, but without a dhcp server(like what routers have built in), the systems do not know what ip to use.

Actually, you technically don't need to worry about addressing because APIPA (auto private IP addressing, i.e. 169.254.x.x) applies. When an interface configured for DHCP cannot successfully lease an IP address, it will fall back to a 169.254.x.x address with a netmask of 255.255.0.0. Once both computers have APIPA addresses they will be able to communicate normally. In practice though, it's a good idea to assign IP addresses because it makes things simpler and you don't have to wait for DHCP to fail for an IP address to be ready for use.
