Ethernet cables

You will probably have to buy Ethernet cables.

  • If the cables go directly from computer to computer (or any two Ethernet devices, like a Mac to a printer), you need crossover cables.

  • If the cables are going from the computer into a hub, router, or switcher, or into a cable or DSL modem, you need straight cables—not crossover.

To tell if an Ethernet cable is crossover or not, hold both ends up, facing the same direction, with the locking clip facing up. Look at the colored wires coming through the end.

A straight cable has the colored wires in exactly the same order.

A crossover cable does not have the colored wires in the same order.
