Please don't follow either of these wiring diagrams. It's very important that pin 3/5(or 4/6, depending on how you look at it) are swapped on both ends. You want: (T-568A) White/green, green, white/orange, blue, white/blue, orange, white/brown, brown Sometimes you'll see (T-568B, preferrred for new installations) White/Orange, Orange, White/Green, Blue, White/Blue, Green, White/Brown, Brown. Both will work the same. For crossover: Do above, one side the orange/blue/green/brown setup, and the other side the green/blue/orange/brown setup. If you don't swap the 3/5(4/6) pins, your cable will might work, but you'll get massive crosstalk, especially over distance or in an electrically noisy environment. Please see: http://www.escape.ca/~droopy/ethernetcables.html http://www.incentre.net/incentre/frame/ethernet.html Also, see: http://catalog.belkin.com/IWCatSectionView.processs?IWAction=Load&Merchant_ID=&Section_Id=522 http://www.startech.com/cable/networking.htm Because that's a LOT easier and more reliable way to do it! If you are making your own cables, proper cable testers cost far too much money. I make do with an old Fluke 620, but it isn't rated for 100mbit or gigabit.
