Samsun Mobile Broadband not connecting

[Vishnu V]

Hi
I have a Samsung C5212 mobile. I use it this as mobile broadband modem in Ubuntu 10.04 without any problems. But in maverick I am not able to connect it to Internet. I tried both bluetooth and data cable. Both fails

I googled about the problem and got command nmcli. But gives an error message

vishnu@vishnu-laptop:~$ nmcli con up uuid f99fc3b0-85fa-4bb5-8664-ff1e2f3e0d84 iface  /dev/ttyACM0 
Error: No suitable device found: device '/dev/ttyACM0' not compatible with connection 'AIRCEL'.

Results of nmcli con list and nmcli dev

vishnu@vishnu-laptop:~$ nmcli  con list

ttyACM0    gsm               disconnected

This problem is only for SAMSUNG mobile. I tried Sony Ericsson K750i,Nokia 3110 which do not have any problem

Please help . Thanks

I am having a similar issue that seems to be related. Though connecting through the NM applet GUI does work initially, the connection will occasionally drop out resulting in an inability to connect until the computer is restarted. Interestingly, even while the modem/computer are still in "compatible" state, nmcli reports the same error as above:

Error: No suitable device found: no device found for connection 'XXXX'.

and also

Error: No suitable device found: device 'ttyUSB0' not compatible with connection 'XXXX'.

when 'iface ttyUSB0' is included in the nmcli command.

For reference, the device I'm using is a Huawei USB stick, with lsusb reporting:
ID 12d1:1404 Huawei Technologies Co., Ltd.

I am using the most recent versions of network-manager and modemmanager, namely 0.8.1+git.20100810t184654.ab580f4-0ubuntu2 and 0.4+git.20100809t153145.be28089-0ubuntu1, respectively.

Any help would be appreciated, and commandline control of NetworkManager would be very useful in this case (since the system is functioning as a headless gateway for the network).

Thanks to all!

By using data cable
1. Connect your mobile to computer. System will detect the a new gsm modem is connected Select configure mobile broad band , if not go to system -> preferences -> network connection under mobile broad band add new

select country provider and select APN

now you can connect to Internet from network connection.
