@Schizophonic I have the Cloud Gateway Ultra
@Caged mentioned, a PoE switch and a U6 Pro AP. When I set it up I put the AP on a 3D printed stand, so it's pointing upwards, downstairs in my living room as a temporary measure to see what I may or may not need to do to get whole house coverage. My house is a 1950s 2 storey, 2 bed brick house with solid walls and as it turned out the AP covers the whole house with no issue with 4k streaming via WiFi anywhere.
As it looks like a flying saucer that's landed, I'm happy with it as it is. You never know, depending on your house you may get away with minimal outlay.
