Ask HN: Routers for Remote Work in 2019?

My wife and I both work from home (on a Verizon DSL circuit, supposed to be 3 down but we barely get 1.5 most days). Fiber is being installed in March/April so we are told.

I am using a Linksys WRT1900AC and recently the WIFI is failing. None of our Wifi devices connect reliably. Linksys dropped this model for software updates. We have had this router since April 2015.

There are so many routers out there. It makes my head spin!

I need a stable, well supported router in 2019!
