Ubuntu 24.04 does not display all available networks and cannot connect to Android hotspot

[Georg Dahmen]

Ubuntu only shows 4 available networks although there are many more. All networks should be displayed.
When attempting to connect to an Android hotspot (SSID: ge, Password: 1234, Security: Either WPA or WPA2, with visible SSID, Device identification: Standard or Personal Hotspot), the SSID is found, and the password can be entered.
After a brief connection, an error message appears: "Connection failed - Activation of network connection failed" and the Wi-Fi symbol is deactivated.
After this error, entries such as "ge", "ge 2" and "ge 3" appear in the list of saved networks, depending on how often the connection was attempted.
Deleting the saved networks does not solve the problem.
Additional information:
Ubuntu version: [insert your Ubuntu version]
Network controller: [insert the type of your network controller]
Android device and Android version: [insert your Android device and version]
Steps to reproduce:
Open network settings in Ubuntu.
Search for available networks. Observe that only 4 networks are displayed, although there are more available networks.
Attempt to establish a connection with an Android hotspot (SSID: ge, Password: 1234, Security: Either WPA or WPA2, with visible SSID, Device identification: Standard or Personal Hotspot).
Enter the password for the Android hotspot.
Observe that the connection is briefly established and then an error message appears: "Connection failed - Activation of network connection failed".
Check the list of saved networks and notice that there are now entries like "ge", "ge 2" and "ge 3", depending on how often the connection was attempted.
Try deleting the saved networks and notice that the problem persists.
Expected behavior:
All available networks should be displayed in the network settings.
Ubuntu should be able to connect to an Android hotspot without receiving error messages.
There should be no duplicate or numbered entries for the Android hotspot in the list of saved networks.
