HEre is an explanation that I made in another topic. I decided to make it a main topic .... because I thought this could help others.... in case it is not seen in the other topic 
Questions.... please ask.
OR if you do not understand something, I'll try to explain it better.

but why use a link cable? If you have a router, that is much nicer.
I think a PC crossover cable will work as well.
A router allows you to connect to other PC's.... but you can hook the LAN cable direct from the BBA to a port on the router. BUT you cannot hook a gamecube up (IE Gamecube to Gamecube) with just 1 normal LAN (ethernet... cat 5 or 5e) cable.
If you don't want to buy ... or if you don't have a router, you can MORE THAN LIKELY use a cross over cable.
Basically..... it is a normal LAN (Ethernet cat 5 or cat 5e cable) but its not a straight cable. The switch the pairs on on of the RJ45 connectors. This allows you to hook 2 computers together WITHOUT a router via network cable.
see what happens in a router (or a switch) has both (lets say Gamecubes) hooked up to it via 1 lan cable to each broadband adaptor through 2 different router (or switch) ports. When One Gamecube sends information to the other.. .this is what happens:
Gamecube 1 sends info that travels up the lan cable to the router (or switch). The router (switch) "twists" the communication and sends it down the lan cable to Gamecube 2. The Gamecube 2 sends back to Gamecube 1 in this same manner.
The Cross over cable does the same thing, but in 1 cable.
There are benefits to using a router/switch as opposed to a crossover cable. That is the router/switch tends to help manage the packets better (back and forth between the systems). The crossover just sends raw data back and forth. I am not getting into this very much as its more advanced.
Also, my Gamecube 1 and 2 analogy came from a PC 1 and 2 anology that works in the same concept.
You can get crossover cables at any computer store. Also, I am going to test this out and let you all know if it works
I hope this makes sense :lol does it?
*** The difference between a router and a switch is that a switch is just for connecting computers together. A router does the same thing but has extra features that CONTROLS what computers connect and what ports..etc. A switch does not do that. Anything on a switch can be accessed (with the proper computer settings..etc).
