I put in 2 CAT6 wires to every room in the house (4 in my office, 4 in garage), with one big PoE switch in the garage.

Everything with an Ethernet port is wired, wifi is for phones and tablets only (a few UniFi WiFi 6 APS).

Works great!

Internet has never dropped for me while working, family loves the always working NAS streaming via wired Apple TV.
