Thanks for the logs. It might not be a problem with Network Manager. It's indeed not crashing nor emitting errors.
I missed the part from your bug description where you said that "ifconfig" hangs when the problem happens. That points to some issue in the kernel or driver. You can also try the command "ip link show" (ifconfig is kind of deprecated). When the problem starts, does it also hang? If not, does it show the wireless interface? Also, when the problem starts, do you see error messages from the driver (mt7921e I believe) or any network related errors (stack traces for example) in the logs from "dmesg"? You can check that with "sudo dmesg".

Soon after the NetworkManager started misbehaving, with all connections to the internet becoming idle now and then. When this event happens the only way to restore internet access is to reboot the system. If initially these events were occasional, they now take place 3 or 4 times per day, often after signing in from the lock screen. So far I was not able to verify whether NetworkManager is actually crashing, the Settings programme reports "NetworkManager not running" (see attached image). However, in the command line `systemctl` reports an active service: ``` $ systemctl status NetworkManager ● NetworkManager.service - Network Manager Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled> Active: active (running) since Sun 2024-08-27 18:21:44 WEST; 2h 18min a> Docs: man:NetworkManager(8) Main PID: 1149 (NetworkManager) Tasks: 4 (limit: 18646) Memory: 12.2M (peak: 28.6M) CPU: 836ms CGroup: /system.slice/NetworkManager.service └─1149 /usr/sbin/NetworkManager --no-daemon ago 27 19:34:08 Symbolic NetworkManager[1149]: <info> [1724006048.8961] man> ago 27 19:34:08 Symbolic NetworkManager[1149]: <info> [1724006048.8965] dev> ago 27 19:34:09 Symbolic NetworkManager[1149]: <info> [1724006049.1482] dev> ago 27 19:34:09 Symbolic NetworkManager[1149]: <info> [1724006049.1484] dev> ago 27 19:34:09 Symbolic NetworkManager[1149]: <info> [1724006049.1488] dhc> ago 27 19:34:09 Symbolic NetworkManager[1149]: <info> [1724006049.1488] dhc> ago 27 19:34:09 Symbolic NetworkManager[1149]: <info> [1724006049.1489] dhc> ago 27 19:34:09 Symbolic NetworkManager[1149]: <info> [1724006049.2049] dev> ago 27 20:33:50 Symbolic NetworkManager[1149]: <info> [1724009630.5340] man> ago 27 20:33:50 Symbolic NetworkManager[1149]: <info> [1724009630.5344] dev> ``` But if I try to restart the service, the command line just hangs up: ``` $ ping 1.1.1.1 ping: connect: Network is unreachable $ sudo systemctl restart NetworkManager ``` Also from `ifconfig` there is no response: ``` $ ifconfig -a ``` Please let me know if there is further useful information I can report.
