I think it works now. The only thing that helped was setting:

[connection]
wifi.powersave = 2

in the file

/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

[dubhater]

They are just warnings. I got the first one too. It's fine.

[tomaspinho]

Yeah, power management doesn't work well with this driver as described in the README.
