I am just noticing in the new rental apartment how much I miss the direct cable connection. Fortunately, I can still connect my PC directly to the router with a cable. Everything else unfortunately has to be solved with WLAN. rick2018 is, of course, far from average. It’s just a hobby ;)
Double sockets in the living room by the TV, at the workplace(-room), and in the children's rooms should already provide good relief. Additionally, at least once per floor LAN to the ceiling for APs. Whether you start connecting every single device with a LAN connection (e.g., printers, internet radios) to LAN instead of WLAN remains to be seen. The important thing for now is the stationary work and streaming devices that run for a long time and exchange a lot of data without wanting to experience speed losses or connection problems.
