My old college roommate moved into an apartment above mine. He has his own Internet via cable and I have mine. I am trying to include his machine as part of my workgroup/homegroup LAN network in Windows 7 without me sharing his Internet Connection or him sharing mine. But we'd like to be able to access each others files like music and tv-shows, we also work together in a graphics firm so I'd like the ability to transfer large PSD's over CAT5. Might also try video gaming. Basically I'm seeking a physical connection, wireless is not an option.
Is that possible? Can it be done using one router or do I have to use two, one for each machine and then connect the routers? Reason I ask is he's connected straight to the modem, I'm connected through a router.
Thank you.
