I have 2 laptops(both macs) connected to the same wireless network. Today I wanted to transfer a large file from one to the other so I got a crossover a cable and connect the two laptops directly to each other.
I wasn't exactly sure what would happen, it seems as though when I transfered the file they used the slow wifi connection. I had to disable wifi on one of the laptops in order to benefit from the increased speed of the ethernet cable.
Can someone explained how this setup actually works and what decides what connection is used?
