Mobile broadband connection doesn't connect automatically

[maXmo]

In connections settings I have 2 connections: wired and mobile broadband. I reset autoconnect option for wired connection in case they could conflict and set the autoconnect option for mobile connection, but when I insert usb modem it gets detected, the connection shows up in the network manager for connection, but it doesn't connect on its own. Is it supposed to work?

system is mint 14.1 mate 32bit

When I insert the modem, syslog looks this way:

At this point the connection shows up in the netwok manager, but doesn't connect automatically. I connect and syslog continues:

and so on

what's the problem?

[mank_in]

search network connection from menu. select mobile broadband tab select add or edit connection. At least you need insert APN, username and password

[maXmo]

The connection was created and works if I connect it manually, APN, username and password are correct. It just doesn't autoconnect even if I set the "autoconnect" checkbox in the connection properties.

[mank_in]

I didn't bother anyway with that. if you select connect automatically you still need select enable mobile broadband in network connection applet . Maybe this help : http://askubuntu.com/questions/82255/ho ... nd-on-boot

Well, anyway, this is the bug report: https://bugs.launchpad.net/ubuntu/+sour ... bug/848164

[maXmo]

I resorted to an udev rule, that's a little more technical.

Solution 1:

1- create a shell script as follows (Replace "Tunisie Télécom / TUNTEL WEB DATA" with the name of your Mobile Broadband connection name):

Code: Select all

#!/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 <name of the network connection>. 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 "Tunisie Télécom / TUNTEL WEB DATA"
        #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  
done

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 :

1- get the attached script below

2- extract it to your home folder (or somewhere safe) and make it hidden by placing a dot 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 "Tunisie Télécom / TUNTEL WEB DATA".





That's it guys!
