Router

Ubiquiti EdgeRouter X Router

Might be a little harder to configure, but this tiny box is a rock-solid alternative to a consumer home router. Pair it (and power it) with a Unifi access point and the PoE injector comes with it.

WiFi Access Point

Ubiquiti Unifi AP-AC-Lite Wireless Access Point

A tiny disk that runs circles around consumer WiFi routers. Powered via the network cable, so you can place it where it needs to be, without worrying about power outlets. For large spaces, a few of these make a great team.
