However there is one small problem. I am trying to hook up a second xbox in the bedroom at the other end of the house with the computer. I dont want to purchase and run another network cable, and I also have HORRIABLE luck wirelessly (its just crappy signal in the bedroom!) so I need to have a WIRED connection to the computer and the xbox, without running another wire.
Someone suggested that I simply place my older/extra router at the end of the cable running into my bedroom and then wire the desktop and xbox into that router. The problem is, that neither the computer or the xbox can see the internet or other computers, almost like there is a firewall on older/extra router that I cant get past... so any suggestions on how to set this up without buying and running more cables???
