Ubuntu – Problem with connecting mobile broadband in Ubuntu 14.04

14.04bug-reportingmobile-broadbandnetworking

When I plugged mobile broadband top right bar new mobile broadband option appears then immediately disappears then again appears then immediately disappears and so on…

If I click on new mobile broadband immediately then it gives error when applying settings because modem disconnect before I configure it. I have idea net-setter (similar to mobile partner of huawei)

enter image description here

On Ubuntu 14.04 I can't connect by using it because of above mentioned problem.(Unstable detection of mobile-broadband)

Wired connection (USB tethering from android) is working fine.

Thus, How can I Solve It?

Solution that works for me:

First stop modemmanager by sudo stop modemmanager.
Then plug net-setter & wait for 20-30 seconds.
Then start modemmanager by sudo start modemmanager

Now when modem (net-setter) detected ; it is stable hence, after connecting, I get stable connection until disconnect or unplugged!

But it is not permanent solution as I have to follow above method each time to get stable connection. So, any other solution will be appreciated.

Note that : Directly restart modemmanager by sudo restart modemmanager not helpful for me.

Additional info: Actually there is no need to start/stop service network-manager entirely. Only go for modemmanager.

You may try connecting from the command line. First create a new mobile broadband connection. To do so:-

Connect your modem. Then select 'New Mobile Broadband connection...' from the panel(aka menu bar) as shown below.

enter image description here

Then in the following window press continue.
Then select your country.
In the subsequent window select your ISP.
Then press 'Continue' and then 'Apply'.

Now open the terminal with Ctrl+Alt+t . Then type the following command :-

nmcli connection

An output similar(not exactly) to the one below will be shown :-

NAME                      UUID                                   TYPE              TIMESTAMP-REAL

As you can see the output displays all the connections that you have created. Now in the above case if I have to connect with 'BSNL/CellOne New GPRS/3G' then I will type the following command:-

nmcli connection up uuid a1f89d7a-12d0-4ef8-b76d-cb6e31b11697

As you can see I have typed the UUID of the connection that I want to connect to. So according to your connection you have got to give the UUID in the above command.
