PS.
If you are going to go for a Zyxel, because you said you wanted wireless AC, can I just re-iterate that the model you need would be the VMG
8924-10A
my personal choice for a wireless AC device would be the Zyxel VMG8924.
The 8324 and 8924 look the same, but the 8324 is only wireless N.
Although saying that, most will agree that the the range of the 8324 is pretty good. In fact unless I was stood practically next to the router, my 8324 gave a better speeds than one AC device I tested.
