I'd appreciate some pointers! Thank you in advance.
In cases like this, more verbose NM and wpa_supplicant logs are helpful. Increase NM logging level by setting "level=TRACE" in the [logging] section of NetworkManager.conf. For wpa_supplicant, add '-ddd' to the command line argument. Both changes require a restart of the daemon. Since those logs can be quite verbose, if you are using systemd-journal you should probably disable rate-limiting by setting e.g. "RateLimitBurst=0" in /etc/systemd/journald.conf. Beniamino
