I went out and purchased a Netgear R7000. I know, it's overkill for a repeater, but I did it. And it's smoking friggin fast. So now, with two wireless AC routers, I have no need for the cable. And when I move, I can decide which one I like better and just use that one. I think the R7000 is going to win out over the AC66R. This thing is a badass lol.
