Okay, this has gotten quite specific now...
I took the floor plans and started to think about where electronic devices with LAN cabling could be placed. On the ground floor, we are already quite far along with the furniture planning, but on the upper floor, we are still very uncertain. The drywall in the bedroom will probably be removed because otherwise, the bedroom would be too small due to the sloping roof.
The two circles in the hallway areas could become two access points on the ceiling.
The lines on the walls could be walls where internet via cable is needed.
The connections themselves + router should of course be located in the utility room.
Ground floor:
Hallway = Access Point
Living room = TV, receiver, game console...
Guest/office room = PC, game console, possibly also TV/receiver
Upper floor:
Children’s room = later at some point TV, receiver, game console, PC
Bedroom = TV/receiver
