Hi all,
First of all, if you have the instructions to do it in any other OS that is not windows 8, just save your self the time.
I used to share the internet from my windows 7 laptop via an ethernet cable. Now I got a windows 8 computer and it doesn't work like that. I went to my internet connection/properties/sharing but when I plug the desktop to the cable (windows xp, though I also tried sharing to a windows 7 desktop) the machine doesn't receive anything.
Note that I'm looking for an answer to this, I am not considering buying a USB wifi adapter for the other machine. If you don't have anything valuable to contribute, keep it to your self.
Those who contribute with an insight to my question, Thanks!
