This is a pretty unorthodox situation so I would appreciate any bit of help
from friends here. Here's a diagram of the physical set-up. It'll help you as
you read my explanation.

I have one D-Link DI-624+ Wireless Router that is connected to the internet
through a cable modem in my home. I currently have two desktops connected to
that routerby network cables while a third is connected wirelessly to the
router through a D-Link DWL-G122 Wireless G USB Adaptor without problems.
This third desktop, which I now call D3, has two network ports. I have a
fourth unconnected desktop (aka D4) physically located adjacent to D3.
However, as I do not have a switch or an additional wireless adaptor, and
both D3 and D4 are too far from my router to run a cable between them and the
router without having to drill holes in the walls or ceiling, I decide to run
a network cable between one of the LAN ports of D3 and the LAN port of D4
instead. Obviously, it does not work. I tried running the Network Setup
Wizard on D3 such that the wireless connection is configured to be shared by
both its LAN ports (it has two LAN ports, remember?), but both LAN
connections of D3 and D4 say that they are completely disconnected even
though there is a cable running between them. Can anyone help me out here?

I hope I didn't confuse anyone with this explanation. :)

Connecting two computers directly to each other requires a crossover
Ethernet cable. A regular Ethernet cable won't work, and both
computers will say that the network cable is unplugged. Crossover
Ethernet cables are available at computer and office supply stores.

Internet Connection Sharing uses the 192.168.0.x IP address range. If
the wireless router currently uses that range, you'll have to change
it to a different range, such as 192.168.1.x, to use ICS.

Instead of using Internet Connection Sharing, you can try creating a
network bridge on D3 between its wireless and wired Ethernet
connections. Not all networking hardware works with a network bridge,
but it's worth a try. If it works, you won't have to worry about the
IP address ranges.

Thanks so much.. I thought it was just a simple case of wiring a regular
cable. It seemed so possible.. until now. I do hope that bridging it will
work.
