Apple has gotten out of the router business so I can no longer recommend the Airport devices. That has now left an opening for other companies to fill in the void. The two products I have been happy with over the last few years are:

1. Orbi by Netgear
2. Velop by Linksys

Both of those systems do a great job. They can be a little cumbersome to set up but once setup, they work very well and are stable. I’ve set up many of each system and have had very little negative feedback. The only negative thing I would say about both product lines is that they are convoluted. There are too many models from which to choose. If you’re sitting on 2000sq feet however, almost any of the current packages would do just fine. I think the Apple store is selling the Orbi systems but I’m sure they’re available at Best Buy as well as online via Amazon, etc...
