That doesn't sound like a good advice from the internet.

First, enable debug logging. For that, edit
/etc/NetworkManager/NetworkManager.conf to have a section

[logging]
level=DEBUG


then, restart NetworkManager, reproduce the issue and show the logfile.
The logfile you will find somewhere in syslog, search in /var/log.

Thomas
