NetworkManager stops running after disconnecting broadband mobile card

[pvanderploeg]

Binary package hint: network-manager-gnome

I have a Dell laptop Latitude D410 running Ubuntu Intrepid (8.10). On my way to and from work I use a Broadband UMTS card (Qualcomm 3g CDMA model GT 3G Quad) to connect to the mobile network of KPN in the Netherlands. Ubuntu Intrepid recognizes the card without any problem and I connect to KPN's mobile network by choosing gthe appropriate radiobutton in NetworkManager. Every now and then however, the connection is lost due to network coverage problems. When that happens the NetworkManager stops running and I have to restart it manually (sudo /etc/init.d/NetworkManager restart) to reconnect to the mobile network.
package network-manager-gnome 0.7~~svn20081020t000444-0ubuntu1.8.10.2
I would expect networkmanager to keep running. Instead it stops running.

when that happens is a new crash file created for you in /var/crash? if so, please submit that by double clicking on it in nautilus and drop the new bug id here.

Hi Alexander
There is no crash file created. Not when I choose "disconnect" in hte
NMapplet menu, and not when I just remove the card.
When I am connected to my Wireless LAN and to the KPN Mobile network at the
same time, the applet shows the Wireless icon (blue pan-flute like).
Choosing disconnect or removing the carde will stop networmanager.

Thanks for your effort

I installed 9.04 today on my test system and got the same results.
Disconnecting the broadband mobile card (or removing it) stopped
NetworkManager. And apart from that, Firefox did not seem to recognize the
broadband connection at all, as it could not connect to any website. Like
it was OffLine, except that Firefox did not state it was in OffLine mode.
Do you think I should report this as a separate bug??

re my previous remark.. I just found out that on my Jaunty test machine with the broadband mobile card, after the connection is made there is no default gateway. The correct default gw is set on my Intrepid machine. That is probably why my Jaunty machine cannot find any anything. I do not know if that is a problem of NetworkManager. I filed it as a separate bug (366711). Does anyone know where to set the default gateway in networkmanager ppp connections??

as requested by Alexander Sack below please find the output from lsusb command and the syslog file after the broadband connection was disconnected due to network coverage problems.
BTW the lsusb output is exactly the same as it was when the connection was still available.
