Earlier quoted context omitted.
I had nothing but problems with typical consumer hardware. Having to restart routers all the time. Dead spots. When family would visit (both my wife and I have large families) they would connect at least 2 devices each to my wifi (tablet, phone, laptop, etc). My wireless would just tank. They would always ask me why my internet was so terrible. Last year I bought an Edge router and a higher end Netgear hotspot. Works…
Ubiquiti Unifi Access Points just work. I too have bought a variety of high end consumer devices (for a small business), and they all crash or randomly drop out. Disable wifi radio on router, plug in Unifi AP, solid connection. They are annoying to configure, but have been so worth it. Apple AirPort has also been rock solid.
I did spring for a "Unifi Cloud Key", which is just a small (pack of cards sized), dedicated host for running the Unifi Controller. Makes administration and updates a fair bit easier.
As someone else mentioned, they do require a wired ethernet connection, but the point of that is these are intended as (entry-level) enterprise hardware. Unifi vs. Amplifi is for contexts where 1) the administration overhead isn't a burden and 2) it's preferable to run cable and leave wifi bandwidth available for clients and/or the rich multiple network support (vs. mesh networking). Obviously, #1 means it's not intended for the general consumer market.
