I have an EA9500 from 2016; However, I passed 5 warranty units. Now that the warranty has expired I have purchased a factory refurbished unit to replace my last defective unit. The first updated device broke right out of the box and restarted 1-2 times a day. The second block keeps the connection alive without resetting; However, after a few hours, some computers will randomly get full internet access, and other computers will have limited internet connection, e.g. For example, email and iMessage work, but you can't access anything in the browser. The EA9500 range is exceptional compared to my previous EA9300 AC4000. It was absolutely the best router I have ever owned. However, 7 failures in less than four years on one of the expensive routers indicates real quality control problems.
