You're using a 568-B cable. Most structured wiring nowadays is 568-A. Are you plugging it into a wall jack, or connecting directly?

Although I'm not sure that makes a difference if both ends of the patch cord have identical terminations.

you sir are 100% correct....There is nothing wrong with the new cable(unless you made it then % goes up) it is just not “Pinned Out”for your application.SAY CHINA not BELKIN.There is a dif and chepo mfgs wont go into detail on the box.
With both connectors side by side,scope it out.As long as each pin has the “SAME” color on it at each end it should fly.Compare 50 footer to 10 footer
