The Netgear X6S is basically to make up for the fact that its predecessor, the X6 was underpowered anyway. And by that, I mean that it was unable to saturate the WAN pipe which is a problem if you have Gigabit broadband service. This was especially a problem since Comcast has been giving this router to customers for its Gigabit on coax service (which I have). I have been trying to figure out why I was not getting 900+ mb/sec performance on any speed test until I stopped assuming that this Netgear gaming router actually had decent routing performance. As it stands, the best it can do is 700 mb/sec and usually ends up being 500-600 mb/sec on average. How Comcast never tested this before giving it to their performance-minded customers is...well, just Comcastic.
