is this the mbm plugin used? consider to post the _full_ modemmanager debug output.

Sorry, please find the full output of

# killall modem-manager; modem-manager --debug 2>&1 | tee log

attached. Is there more?

I see this too, and the asked output is provided.

Mobile Broadband worked for me in 9.04. In Karmic, it works the _second_ time i try to connect after booting. The first time nothing happens after registering with the gsm network, so i "disconnect" and connect again. The second time it works. After disconnecting manually, I can't reconnect again unless I reboot.

My card is a 5530 if it makes any difference.

This bug was fixed in the package modemmanager - 0.2.git.20091014t233208.16f3e00-0ubuntu1

It's still not working, I've attached a new debug log (yes, I've rebooted after the update)

I just tried connecting a few times and it worked... besides the segfault in the attached log.

andreas: the 5530 is a completely different card (a Sony Ericsson OEM as
far as I know), please file a seperate bug for your issues.

Herr Schmidt: and close it again because the issues with the 5530 are fixed? :-)

its fixed. all mbm cards should work well now.

sry, thought it was a mbm/ericcson card too. its a novatel according to your log. and the issue is that you dont register. seems there is no CREG=0 or =1 send at all for you.

please try the two variant patches i will attach ... for each do:

sudo apt-get build-dep modemmanager
sudo apt-get install devscripts
apt-get source modemmanager
cd modemman*/
patch -p1 < /path/to/patch
debuild -b # ignore if this fails with gpg keys not working
sudo dpkg -i ../modem*.deb # this installs the modemmanager

please do that for both patches and see if either one works.

oh ... you usually dont need to reboot in between. run sudo killall modem-manager after installing the new package.

in case your log looks completely different, please reboot anyway to be sure that we don't deny this patch because your modem goes into a bad state.

None of them work, I have attached both debug logs. The card works fine
with wvdial and a very simple "ATZ\nAT+cgdcont=1,"IP","cda.vodafone.de""
init. Could it be a firmware bug that the card is not correctly
reporting the registration status?

Bernhard

yes. firmware could be a problem. did it work for 0.7.x for you? any chance you could test that without modemmanager? maybe try if the bits in https://edge.launchpad.net/~network-manager/+archive/ppa can still be used (downgrade and remove modemmanager).

if it works i need a log... start NetworkManager --no-daemon from console with NM_SERIAL_DEBUG=1 in env for that.

also you could just try and see if using CREG=1 does change anything.

No, it never worked with earlier NetworkManager versions either. As far
as I remember it was the same issue (nm kept polling for AT+CREG?). But
I never investigated further.

This is the most current Dell-branded firmware available, I apparently
cannot flash vanilla Novatel firmwares into the module.

> also you could just try and see if using CREG=1 does change anything.

Essentially your second patch with CREG=1 instead of CREG=0? Will do ASAP

> Essentially your second patch with CREG=1 instead of CREG=0? Will do ASAP

yes. any chance to test that?

I have exactly the same problem. Same output in the logs. Same Card (5520) in a Dell XPS M1330.
What i've not tried is to connect via wvdial. But i think it would be the same.

Is here something new? Last post is from October, 31 ?

Is a Firmware upgrade usefull? How can i find out what firmware is installed?
Can i do something else ?

Hi Alexander,

sorry for the delay, AT+CREG=1 does not work either. Please find
attached the logfile.

Best Regards,
Bernhard

I have 413c:8137 5520 (3G HSDPA) Minicard Status Port
, could connect in earlier config. Now logs are

FWIW, doesn't work in lucid (modemmanager 0.3-0ubuntu2) either. Same issue, keeps polling +CREG?

It works same hardware just removed harddrive and updated graphics board, then liveboot diskless and 3G connects perfectly. It (live diskless after removing seagate harddrive keeping the 3G) works with diskless jaunty very well today without installing for very good demo and our very important trend mobility (and tourism).

I tried it without removing any Hardware. I just bootet from a Hardy Heron Desktop Live-CD. The GSM-Modem worked once(!). I could connect to the internet and browse. But when i disconnected the connection and tried it again, it stocked as before.

Very strange 8-|

Anyone tried it with Lucid yet ?

This did not work with lucid, but it does with Maverick. So there is some change in between that makes it work.

I will create a modemmanager debug log of a successful connect later.

Here is the modem-manager --debug log

Have you tried if this still fails in Ubuntu Natty?

It works for me!
