these onhub routers, need more ethernet ports and USB ports for storage and printer sharing, and they are really not worth upgrading from your ISPs router, especially when they are coming with AC and gigabit.
I have had three Asus ac routers and they have all had issues. One is still working, but not very well. I am now using it as an extender to an Apple AirPort Extreme, but my devices drop connection to it randomly, so I mostly connect directly to the AirPort Extreme.
Based on my experience, I wouldn't buy another Asus-made router.
