I've never met a reliable WiFi router. Even the expensive well-reviewed models have been disappointing. For years now I have used ubiquiti Unifi access points (UFO looking) for the WiFi (small business, home, parents, installed for multiple different friends) and been very happy with connection reliability and range. PoE means you can install them where they provide good connectivity over many rooms. I've often plugged them into friends shitty home routers and reliability has been okay. If you want more complicated router functionality use a small computer and install open source. I haven't really used any of their other gear, and I dislike their privacy policies and web login. I once used one of their point-to-point links and it worked really really well.
