I have gigabit fios. Got a direct gigabit line from a router with kat6. I've seen downloads at 400Mbps. shakes no faster than 350MB/s while standing nearby. I only use it for 5GHz mode. 2.4GHz mode never exceeded 100Mbps. That's not bad performance, but I'm a bit disappointed that I didn't get the full advertised speed of 860 Mbps.
