I need to be able to transfer files between my dekstop PC and my iBook while at home. Right now, I'm using a D-Link router, the desktop is connected using ethernet cable to the router and the notebook is conencted via airport card. But I have an extra ethernet cable if it's required. Can anyone tell me how I can do this? Do I have to set up a file server? Do I have to plug one end of ethernet into the PC and one end into the iBook? I'm sorry, but I'm really confused.
