Network cards capable of 1 gbps speeds are smart enough (and it's actually required by the 1gbps standard) to determine if the cable is crossover or normal and automatically reconfigure themselves to work right in any situation. If the color order is the same in both connectors, you have a straight (normal) cable, if the color order is different in one jack you have a crossover cable (a cable designed specially to be used between two computers / two network cards)

Look at the wires going into the connector. If you have no idea what category it is, chances are it's Cat5e which means it can do up to 1 gbps.Ĭat5 or older cables would be maybe more than 10 years old nowadays, so I doubt you'd use a cable with the exterior insulation all messed up (which would happen in 10 years)
