I'm a bit lucky (if you call writing router code in the 90's luck.) So there's never been a time I needed to make a call for support. I don't know who's been bad or good. (La la la, la la la al...)

If I were to shop a router today I'd find the INTERSECTION of what routers are on TWO LISTS.

1. CNET's list at https://www.cnet.com/topics/networking/best-networking-devices/802-11ac/
2. Amazon Best Sellers at https://www.amazon.com/Best-Sellers-Computers-Accessories-Computer-Routers/zgbs/pc/300189

What am I using today. 2 routers.
1. The ISP supplied UBEE which is surprisingly good.
2. The https://computers.woot.com/offers/linksys-ea9500-ac5400-max-stream-wifi-router by Linksys which was a steal when I needed my own router.
