How do I turn it on? What do I have to do to get my computer to connect at gigabit speeds??? This all started by trying to increase transfer speeds to my NAS (see thread), only to realize that my iMac was only connecting at 10/100 speeds. I'm on Mavericks (10.9). I've bought a NetGear gigabit (GS608) switch to take traffic loads off of my E2000 Linksys router (which should have no problem doing this). I have tested several Cat5E cables that my NAS, switch and router all recognize as gigagbit. I just bought a few feet of Cat6 and still it isn't working. What do I have to do?
