I ditched my consumer Asus router (RT-AC68U) for Ubiquiti Networks a long time ago.
You do need some level of IT knowledge to set them up, but they're in the same price point (or a negligible difference) as some of the "high end" consumer routers, and are 100x better.
Moving from Asus to UBNT gave me far better coverage and signal quality, and the UBNT devices let me manage my network however I want to. The Asus was just far too restrictive for me, and I spent over $200 on it.
For almost the same cost, I picked up a UBNT router and access point, and couldn't be happier. And all of the "our Wifi sucks!!" complaints magically went away!
