I managed to work around the WiFi problem.
Usually when installing software, first thing you do is upgrade the whole thing. So when you run the firmware upgrade, it gets you into trouble with this chip.
This is true in October 2020, later versions to be confirmed.
The current drivers are extremely unstable, older ones are better.
You can get the old ones back (and keep them) using:
wget archive.raspberrypi.org/debian...90114-1+rpt4_all.deb
sudo dpkg --purge firmware-brcm80211
sudo dpkg --install firmware-brcm80211_20190114-1+rpt4_all.deb
sudo apt-mark hold firmware-brcm80211
sudo systemctl reboot
This solved it for me and i am happy surfing through the pi with 5 devices for longer than 6hrs already, while others join and leave the network (read: works as expected currently).
