WiFi authentication required after a timeout

Recently, there is the occasional appearance of a dialog for WiFi authentication. I suspect the timing of the dialog is driven by a timeout. When it appeared I clicked on it and it showed that my WiFi password was already known to Ubuntu. How can I prevent this dialog from appearing?

How to prevent real MAC address leakage
pk flag

Normally you cannot change the MAC address through network manager until after you've connected to a network and exposed your wifi card/devices real MAC address. How can I ensure that every card or usb adapter immediately gets issued a randomized or specific address the second I plug it in and never leaks the real address? I noticed that ubuntu doesn't randomize wireless network scans either.
