My personal current setup is 10 year old desktop PC with a dual Intel NIC running OPNsense as my router. This is more than enough power and aside from a relatively long reboot time (about 80 seconds or so) it works wonderfully. Connected to this router is my WAN (Frontier fiber) in one NIC port and a TP-Link unmanaged Gigabit switch with POE ports on the other. The Wi-Fi is provided by TP-Link Omada access points managed by a local hardware controller (TP-Link sells these and they support many more APs at a time than I ever would need). This setup has been amazing in terms of managing it and in terms of user experience. Fast Wi-Fi, built in roaming over my 6 access points, and a router that is powerful, fast, and very flexible to manage with a great community behind it. Would have loved an open source AP solution but Omada at least does work well just like most TP-Link stuff.
