Did you try connecting from command line? – VenkiPhy6 Apr 21 '14 at 9:30
No, I didn't. I don't know the command – Ujang Karnadi Apr 21 '14 at 9:33
Ok. I will post it as answer. Try it. I wont guarantee that it will work, though. – VenkiPhy6 Apr 21 '14 at 9:34
I hope it will work. . . thanks before – Ujang Karnadi Apr 21 '14 at 9:36
I'm not too sure it would help but its worth having a look through on this topic. – AzkerM May 7 '14 at 4:58

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

BSNL/CellOne New GPRS/3G  a1f89d7a-12d0-4ef8-b76d-cb6e31b11697   gsm               Monday 21 April 2014 03:22:39 PM IST

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.

@UjangKarnadi Sorry I couldn't help. But don't go for a new modem so quickly. Be patient and wait for more answers. Then go for a new one.. – VenkiPhy6 Apr 21 '14 at 14:01
It's OK. . . The good think is I can know more about command line. . – Ujang Karnadi Apr 21 '14 at 15:46

Hi and welcome to AskUbuntu. Answers that contain just a link are generally considered to be comments. For a post to be considered an answer it should have enough "persistent" information to provide a solution. ie. the link might become unavailable, so your answer should provide enough information to reproduce the solution described in the linked article. Please edit your answer to make it so. – hmayag Apr 21 '14 at 11:38
and the link is broken. – Roland Kofler Jun 4 '14 at 6:10
