Authorization repeatedly requested before connection finally suceeds

[rustycanb]

Network Manager asks for authorization repeatedly (up to five or six times) after reboot.
The connection is only successfully connected after sudo systemctl NetworkManager restart or nmcli con up [connection] is repeated several times ignoring the password dialogue.
Once the connection is established the device works as expected with good speeds.

Not a problem with the driver or this code. The solution is to include in /etc/NetworkManager/NetworkManager.conf:
[device]
wifi.scan-rand-mac-address=no
restart Network Manager:
sudo systemctl stop NetworkManager.service
sudo systemctl start NetworkManager.service
