Got the bigpipe elite plan, loving the speed but not really reaching its maximum potential as all of our devices at home are on wifi 99% of the time. 

I get around 200-290 Mb/s over wifi on the 802.11 AC network using the Huawei HG-659. I have a 2014 Macbook Retina. 

I've been looking at modems, particularly the Asus AC-68U. Would I see a decent increase in speed? From what I have read online I believe it will cap out around 400-500 Mb/s under optimal conditions.

Has wifi technology not caught up to gigabit internet? Or is there a solution...
