Speed is not the only variable here, stability is too, and over the years, if anything, WiFi has become more unstable if anything, going from „I get internet outside my house” to „don’t lean too much towards the wall in my bed, otherwise the 0,50 Mbit is gonna become even less”.

Really? My phone easily connects to my WiFi everyone in my apartment, from couple floors below it and through the ceiling. I have the router in a wall box. For me with WiFi 6 it just got faster, I didn’t notice any stability issues.
