Public bug reported:

As the headline says. On the support fora that I frequent, many people
report unstable and unreliable WiFi connections because of this. In
those cases, when power management for the WiFi chipset is turned off,
the connection immediately improves a lot.

Therefore the default for WiFi power management should be "off", non
"on".

Workaround for those who don't want to wait for the fix:
sudo sed -i 's/3/2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

Reboot.

When there's no such .conf file yet:
sudo touch /etc/NetworkManager/conf.d/default-wifi-powersave-off.conf

echo "[connection]" | sudo tee /etc/NetworkManager/conf.d/default-wifi-
powersave-off.conf

echo "wifi.powersave = 2" | sudo tee -a
/etc/NetworkManager/conf.d/default-wifi-powersave-off.conf

Reboot.
