I've stopped wasting time with retail consumer grade routers. It's almost like they're designed to fail after ~two years. I'm a heavy internet/VPN user. They all overheat/lock up occasionally (requiring a reboot) if you put a load on them or a high number of concurrent connections. And don't get me started on the crappy firmware they have and they rarely update. If you do go consumer grade, don't spend more than $100 or so.

It's not too much more expensive to step up to a prosumer type product like the Ubiquity AC PRO access points. Slightly more difficult to setup, but well worth the effort.
