hi, I am having trouble connecting my ps3 wirelessly to my wireless modem router which is in my office. Luckily or not I have an unused phoneline that runs from the office to my living room that comes out by the ps3. What I would ideally like to do is use the cable in the wall as an ethernet cable. I have checked the cable and it is a very thin untwisted four core cable. Is this suitable to run lan over, the run is only 8 meters long. I have looked here and it seems that it may be possible but this example does use cat5 cable but does only use four cores. http://www.zytrax.com/tech/layer_1/cables/mixed.html Would I need a port/swich? could i just plug the ps3 directly to this cable if I reterminate the ends of this cable to a RJ45 conection? Any networking guys be able to help?
