My dad will be doing all of the networking and configuring. Have a father with 35 years as a Network Engineer for Unisys Corp was bound to come in handy someday!

Anyways, Let me see if I can show you how this would be.

The image below is an ok rendition of what my apartment looks like. The red dot is where the cable modem is, as well as my room-mate's computer. The other bedroom is mine. The red circles are where I could potentially put the computer. To minimize exposed cable, I am prepared to drill through some walls. Given the layout, what would be the best recommendation as a setup?
