Lan setups

I wish to set up up a new computer as a server. My problem is the computers are in different rooms of my home and I can't run cables to them. Someone mentioned to me the possibility of using ethernet cards that are digital,or wireless, that have a little antenna, so I can transfer data from a server to the other computers.Is this possible??? If so, what MB would you recommend? I was looking at the Intel850 or I845 for this. What can I do to accomplish this. I contacted 3Com, but they gave me no help.

thank u all
