Ethernet Patch or a Crossover Cable what type to use ????
[MOD EDIT: Subject heading changed to assist community]
A feature of Ethernet called MDI-X provides the necessary auto-detection support to prevent signal conflicts. This feature allows the Ethernet interface to automatically determine which signaling convention the device on the other end of the cable expects and negotiates use of the transmit and receive wires in a crossover cable.
Most home broadband routers (even older models) incorporated MDI-X support on their Ethernet interfaces.
Gigabit Ethernet also adopted MDI-X as a standard.
Modern Ethernet devices now automatically detect the use of crossover cables and work with them seamlessly..
