@FEIN buy something for routing and firewalling, and then something else for wifi.place wifi access points (with a wired backhaul aka cable) near where you use wifi the most. add more access points to cover your appartment/house as needed.I use two ancient tp-link eap 245v3 in my house, one per floor, and they are "dumb APs" only translating wifi to cable back to my switch and router. then a firewall/router.you don't need much spec-wise. at my moms place I have a small SBC with two rj45 ports for routing/firewalling and similar dumb APs for wifi, and that setup manages their gigabit connection without issue.
