Binary package hint: network-manager

Hello!
I Have installed Ubuntu 9.04 on my PC and Laptop and have the same problem.
To connect to the internet I use as modem the "Motorola W3m" cellphone.
Ubuntu recognizes it and works fine with it.
But I have the occasional problem with the sustainability of the NetworkManager
I get a message that he is not running. I looked through the file /var/log/messages and found the following message
erick@ubuntu:~$ dmesg | grep NetworkManager

erick@ubuntu:~$

My ubuntu version is:

erick@ubuntu:~$ lsb_release -rd
Description: Ubuntu 9.04
Release: 9.04
erick@ubuntu:~$

I installed the latest updates, but the problem is constantly repeated.
Reading in the web http://ubuntuforums.org/showthread.php?t=1184623

I guess the problem is something with the EVDO mode... but my cellphone do not have the option to switch to "EVDO only mode"... I have noticed too that when I am in the city where i study this problem is less constantly, but when i am in the city where i live the problem is very constantly. The first city is smaller than the second and it makes me think that the problem is really related with the signal mode (maybe the evdo mode is more stable in the places where less people are connected).

sorry for my english, i'm working on it.

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a ".crash" file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.

If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.

I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.
