USB GSM-Modem ID 12d1:1506 doesn't hold the connection

[Full inu]

When I have internet-connection via mobile broadband (that was configured by command 'sudo pppconfig'), USC think i didn't connected. And not only USC - whole system don't think different.
What happens in result:
1) Can't install any app in USC

What happens in other affected packages:
2) Ubuntu One - do not synchronise
3) Thunderbird - don't search new messages
4) Firefox - always starts in Offline Mode
5) Banshee - din't start synchronisation with Last.FM integration
6) Rhythmbox - the same as Banshee

I attached my settings, they have been configured via 'sudo pppconfig' and located at '/etc/ppp/peers/provider' file.

Hi,

Thank you for the attention :)

i used this device:

Bus 002 Device 003: ID 12d1:1506 Huawei Technologies Co., Ltd. E398 LTE/UMTS/GSM Modem/Networkcard

But really it's Huawei, Model E352, adapted for russian mobile broadband company.

Can you attach the output from
 - ifconfig
 - route -n
before plugin the device.

And the

/var/log/syslog

begining with plugin

and after connection

 - ifconfig
 - route -n

again.

Thanks

Syslog is really interesting :)
i also added log after pon command (i have internet-connection only via this).
Maybe it can be helpful?..

Hi,

I have tested and I got the same the problem here.

I think this is a mistake in modemmanager. I will pass you.

Thank you for your cooperation.

I found, that my modem WORKS correctly in Linux Mint 11 <<Rosinka>>. It might help you?
Attached torrent file for this distributive.

Keep in mind that NetworkManager still blund about any "sudo pppconfig" connection that i create.
Since modem works i just don't need this.
