UMTS Modem: network manager / pppd does hang up immediately after successful connect

[andreas]

Binary package hint: network-manager

Hi,

after installing jaunty I'm no longer able connect to a umts network using a vodafone MC950D umts stick. It was working fine with 8.10. From the logs I see this:

Note: The vodafone-mobile-connect-card-driver-for-linux does work as well. But note that this component provides all binaries in /opt/vnc ... so this works different.

please set your APN, username and password in the connection editor. even though the values might not matter, its required for some modems to be set to something.

[andreas (andreas-zickner)]

Hi, APN, username, password where set. These values where set during setup and manually. During the test (logs in this case) the values where already there. (See also attached screen shot)

Same issue with Verizon and EVDO. I can connect fine if I setup my own pppd config file and chat script and run it from the command line.

Hi,

could you please post your pppd/chat config? I would like to check if I
can confirm the 'runs from command line' with my configuration.

thanks

I just used the instructions from here:

[andreas (andreas-zickner)]

Hi, I did that that with the same result! So I can connect using
pppd/chat following the same instructions (changed only username and
phone number).

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.
