How to auto connect Ubuntu 12.04 USB GSM Mobile Broadband Connection on Boot as startup service without user login using Network Manager CLi

This guide is intended as a relatively easy step by step guide to:

  • Create a auto start bash script to start the mobile broadband connection at boot time as a startup service without needing to log in as a user.
  • * Update: Added version 2 of the script that will also auto re-connect the mobile broadband connection if the connection is dropped, disconnected or lost for some reason.

Requirements:

  • Ubuntu 12.04 LTS machine with a USB GSM 3G Modem

1. Setup a new Mobile Broadband Connection and connect.

  • After you have set up a new Mobile Broadband Connection it will appear in the network connections (click on taskbar network icon).
  • In this case our new connection name is : 8ta 
  • Connection 'name' should contain only alpha-numerical characters and no spaces to avoid problems.
  • Make sure the "Enable Mobile Broadband" is activated. (see below)
  • Connect to the internet with your Mobile Broadband connection by clicking on the connection name. In this case 8ta

2. Create a Network Manager CLi startup script for your connection.

  • Open the Terminal Window and enter :
sudo gedit /etc/init.d/mobile-broadband-connect
  • Add the following into the startup script file and save: 
  • Note: Replace the YourMobileBroadbandConnectionNameHere with the name of your connection. In this case our service provider is: 8ta
  • Note: If you want the script to also auto re-connect the connection if lost rather use version 2.
  • Note: If you do not see a codeblock right below this text or see a small empty box before step 3 - please reload this page.

​3. Change the startup script file permissions.

  • By default a new file is not allowed to be executed - so we need to modify the permissions to allow us to run the script at startup..
  • Open the Terminal Window and enter :
sudo chmod +x /etc/init.d/mobile-broadband-connect

​4. Update system startup defaults to include your new script as a service.

  • To update the startup services, open the Terminal Window and enter :
sudo update-rc.d mobile-broadband-connect defaults
  • The script is registered as a system startup service so you can start, stop, or check the status of the script with :
sudo service mobile-broadband-connect start
sudo service mobile-broadband-connect stop
sudo service mobile-broadband-connect status

​5. Reboot to complete installation and auto connect.

  • Reboot your system to complete the installation.
  • After reboot it takes up to 60 seconds before the USB device is active.
  • When active - The Mobile Broadband Connection will be activated and auto connected.

6. Troubleshooting.

  • If it does not connect on startup the most likely problem is that the connection is not available to all users at startup.
  • Click on "Edit Connections..." in the Network Connections Manager dialog window, select Mobile Broadband, select your connection, and click on "Edit".
  • Make sure that the "Available to all users" is selected and click on Save

 

Version 2: How to Auto Re-Connect the Mobile Broadband Connection.

  • The script in step 2 is only to establish a connection once the GSM modem becomes available on the system, usually during boot, but can also be in the form of a USB modem that is plugged into the computer.
  • If the connection is dropped for whatever reason the script does not automatically re-connect the modem.
  • The script was updated in version 2 below to allow for this event. It will keep running in the backgroud and keep trying to establish a GSM connection if it finds the modem disconnected for some reason.
  • Edit the script file created in step 2, by opening a terminal window and entering:
sudo gedit /etc/init.d/mobile-broadband-connect
  • Then replace the original code with the code below and save: 
  • Note: Replace the YourMobileBroadbandConnectionNameHere with the name of your connection. In this case our service provider is: 8ta

Works for the startup issues, thanks very much.

AT last and you beauty!

AT last and you beauty! Thanks to all concerned, I've been trying to do this off and on for MONTHS. While not a unix guru I am a PC guru and have struggled with this one... Most of my problem is plain bad attitude: WHY? when the "Connect Automatically" option is checked does it NOT connect automatically without need for a separate script like this one!?!, etc etc etc. So thanks again for this, I'll try not to be so pig headed in the future.

The connect automatically

The connect automatically setting is for the that user only after login, not all users.

i don't have gui network

i don't have gui network manager , how can i add newconnection from cli ??

Thanks a lot. Script works

Thanks a lot. Script works perfectly. But how can i stop auto-connection (for example while at home and want to use only wlan) Any idea?

To stop just use - sudo

To stop just use - sudo service mobile-broadband-connect stop . You could create a desktop launcher item to make this easier.

Thank you! I use it on my
