Thank you Luís for taking the time to open this ticket, and respond with
the additional logs. I am from the from the kernel team, and I have
looked over the dmesg.log that you have provided.
I don't see any networking issues in the kernel log relating to the kernel, but
I do see that some Virtual Box modules have been loaded which are out of tree,
and unsupported by us.
I see that the "VBoxNetFlt" among other Virtual box drivers have been
loaded. This one is the Virtual Box "Network Filter Driver". I think
there is a good chance that the newer kernel version you are now running
is not playing nicely with the VirtualBox drivers. Can you please un-
install them, and see if the problem still exists? I do not see any
other networking related problems in the kernel log.

Title:
Network Manager stops functioning on Ubuntu 24.04
Status in linux package in Ubuntu:
Incomplete
Status in network-manager package in Ubuntu:
New
Bug description:
I installed Ubuntu 24.04 about a month ago on a Asus Vivobook. 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>

```
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.
Thank you.
