Ask HN: Looking for a stable wireless router

I am working from home (1500 sq. ft.) and I have about 10-20 devices connected to my router. I am looking for stable router, that doesn't need a restart every once a while. Something reliable. I have had bad experience with TP-LINK routers where they have good 5Ghz speed but lose connection on 2.4Ghz. Speed is the second priority for me. Thank you.
