I just got a windows xp pc from my friend that he was about to through away. I want to turn the pc into a sort of media hub where I can store my movies, music, tv shows, etc. However, my office is on the second floor and my router is on the first so I use a wifi card to get internet access up there. I remember reading somewhere that you could share internet access between tho computers using a standard internet cable. Is it possible for me to some how make it so that the windows xp pc also gets internet from the same wifi card on my gaming rig? If so, how would it be done?
