Straight-Through Wiring
Because the 10/100 Mbps port on the access point uses an MDI pin configuration,
you must use “straight-through” cable for network connections to hubs or switches
that only have MDI-X ports. However, if the device to which you are connecting
supports auto-MDIX operation, you can use either “straight-through” or “crossover”
cable.
