Wifi does not connect to home network at startup after upgrade to 24.04

After upgrading to 24.04 the Wifi on my laptop would not connect to my default home network after starting up.

Fix was found here:

In NetworkManager.conf the setting "managed" needs to be set to true.
After that networkmanager needs to be restarted.

Issue not solved.
When laptop is powered off for a long time, at power-up the default wifi network is not immediately found.
On warm reboot however, default network does seem to be found.
