Hi all. I'm hoping a tech savvy dude can help me out here, as I would like to set up a home network and am unfortunately competely ignorant on how to do so. Right now, I have a Mac hooked up to DSL on the second floor. My father would like to put his PC down in the basement and share the DSL connection. Is it even possible for a Mac and PC to share one internet connection? They dont need to talk to each other, just both go online. Would I need to run an ethernet cable down from the 2nd floor to the basement, or would the wireless signal reach it? Any help would be appreciated.
