Looking for similar errors some posts suggest to disable the
wpa_supplicant service as it might be clashing with NetworkManager
starting it on it's own but disabling it doesn't seem to have any
effect.
This seems to happen only when connecting to a particular router, a
vodafone EasyBox (which worked fine before updating to ubuntu 19.04)
connecting to some other router seems to not have this problem
