That's the only thing available.
Right. After that will I need to configure anything or what? The computer aren't even in the same room. Right now I just have my modem hooked up to a hub. Which runs an Ethernet cable to one computer. Then I have another cable from that running up through the wall to the upstairs. Then that hooks to another hub. Then from the second hub I have cables running to my pc and xbox. What all will I need to change?
