Bug Description

After updating from hardy to jaunty (9.04) internet stops working after some time in Jaunty, I did not have this behaviour in hardy, there was no change in hardware. After some time (usually 30 minutes to 1.5 hours) internet just stops working.

There are no error message in the system log, no notifications, everything seems normal but internet stops working. A reboot solves the problem (for a while).

I did find the following in the daemon.log file (at around 21:22 the problem occurs).

May 18 20:48:17 bebodenp1 NetworkManager: <WARN> list_connections_cb(): Couldn't retrieve connections: No such method 'ListConnections' in interface 'org.freedesktop.NetworkManagerSettings' at object path '/org/freedesktop/NetworkManagerSettings' (signature '').

May 18 21:22:45 bebodenp1 NetworkManager: <info> Policy set 'Auto eth0' (eth0)as default for routing and DNS.

I use internet via a cable-modem, and the physical device state isn't changed.

Some extra information, the NetworkManager remains running while this problem occurs. And as workaround instead of rebooting you can do a "sudo /etc/init.d/NetworkManager restart"

sboden@bebodenp1:/var/run/NetworkManager$ ls
NetworkManager.pid
sboden@bebodenp1:/var/run/NetworkManager$ cat *

Will be added in a couple of hours, don't have access to the machine right now.

It's been ongoing since the original report. After every +- 30 minutes of inactivity the network drops out, nothing is wrong with the network itself. And when I restart NetworkManager as above the desktop crashes.

attached syslog file.

The problem occurs at 18:36 when "internet" stops working, I restarted the networkmanager at 18.42

The errors on b43 is something which already happened in hardy (which didn't have the above problem).

Thank you for taking the time to report this bug and helping to make Ubuntu better. We are sorry that we do not always have the capacity to look at all reported bugs in a timely manner.
There have been many changes in Ubuntu since that time you reported the bug and your problem may have been fixed with some of the updates. It would help us a lot if you could test the current Ubuntu version (10.10). If you can test it, and it is still an issue, we would appreciate if you could upload updated logs by running apport-collect <bug #>, and any other logs that are relevant for this particular issue.
