Solution 1:
1- create a shell script as follows (Replace “Tunisie Télécom / TUNTEL WEB DATA” with the name of your Mobile Broadband connection):
#!/bin/bash
while true; do
LC_ALL=C nmcli -t -f TYPE,STATE dev | grep -q "^gsm:disconnected$"
if [ $? -eq 0 ]; then
#jdownloader is still in the download status so stop it because
#internet is disconnected and jdownloader won't resume download
#when connected again
#jdownloader --stop-download
#sometimes I can not get connected after disconnection when
#I click on . I have to disable
#and enable Mobile Broadband
nmcli -t nm wwan off
sleep 1
nmcli -t nm wwan on
sleep 1
nmcli -t con up id "YourMobileBroadbandConnectionNameHere"
#wait approximately 15 sec to get connected
#if anyone can add better command to check for it just comment it :-p
sleep 15
#now connected to internet so start download
#jdownloader --start-download
fi
#it does not worth keep it checking every millisecond.
#my connection will be reestablished within 5-15 seconds
sleep 2
#if anyone can code it better please feel free to comment
#TO-DO:: check for data received. if data < 15 KB after 20 seconds of connection
#reconnect mobile broadband connection

2- Save it and give it execution permission then add it to Startup Applications.
- Now it will connect automatically at startup and if connection is dropped.
- Solution 2 :same thing another method
1- get the a readymade script download
2- extract it to your home folder (or somewhere safe) and make it hidden by placing a period before it like this .network-autoconnection.sh (so that you won’t accidently delete it)3- Give it execution permission like this: rightclick on it, go to “properties”, then navigate to “permissions” then tick “Allow executing file as program”
- 4- go to the Mint menu and type “startup applications”
5- click on “add” then “browse” opposite to “command” field to give the directory of the script (your home folder or wherever you’ve placed it) then give it a name in the “name” field, for example mine is “Reliance smart WAP”
- finished
solution 3:
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 : Reliance smart WAP
- 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 Reliance smart WAP
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
#!/bin/sh
# CD Mobile Broadband Startup Service script v2.0 beta by CD May 2012
# acts as startup service script for nmcli to fire up Mobile Broadband Connections
# user the name of the Mobile Connection as defined in the Network Manager as the 'id'
# USAGE: start|stop|status
#
### BEGIN INIT INFO

echo "[MBC] *** Starting Mobile Broadband Connection."

LC_ALL=C nmcli -t -f TYPE,STATE dev | grep -q "^gsm:disconnected$"
if [ $? -eq 0 ]; then
# now gsm detected, run the script
echo "[MBC] GSM Modem Detected - attempting auto connect"
nmcli -t con up id YourMobileBroadbandConnectionNameHere

echo "[MBC] Hopefully connected now... sleeping for 30sec"
sleep 30
else
# GSM device not detected yet or GMS device already connected - sleep
echo "[MBC] MBC still running - sleeping for 10....."
sleep 10
fi

nmcli -t con down id YourMobileBroadbandConnectionNameHere
ps aux | grep "mobile-connection-connect-2.0.sh start" | grep -v grep | awk '{print $2}' | xargs kill -9
#nmcli -t nm wwan off

# Check network status with nmcli
nmcli -p dev

*)
echo "[MBC] Mobile Broadband Startup Service"
echo $"Usage: $0 {start|stop|status}"
exit 1
esac
exit 0- Add the following into the startup script file and save with name : mobile-broadband-connect.sh
- Note: Replace the YourMobileBroadbandConnectionNameHere with the name of your connection. In this case our service provider is:Reliance smart WAP
- 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
