I know that RJ-45 conectors have 8 pins, but 100BaseT only uses pins 1,2,3,and 6 to transfer data. If I used pins 4,5,7,8 and made an adapter for temporary use, could i use it as 2 network cables? I know it's best to run all new cable, but I don't have the time to run a second wire until a few weeks for now. (this is for my own personal use, not for a customer or anything). My question is will it work, and will there be a diminished transfer rate?
