Ubuntu – Mobile Broadband not showing in Network Manager

mobile-broadbandnetwork-manager

I have very big problem with mobile broadband connections…
I tried on my laptop to connect and searched the web for possible solution, but didn't found it.

The problem is that i DON'T have the menu Mobile Broadband. I have only Wireless and Wired connection. I even don't see the Enable Mobile Broadband! I had success with one USB modem with sakis3g, but on my new Alcate didn't worked.

I've tried also on new freshly installed Ubuntu 12.04 on PC, and again – no menu at all for Mobile Broadband! When I open "Network connections" I have menu Mobile Broadbands and when I add a connection – nothing happens, it shows me "last used – never"

In addition to add – In "Networks" I can't add Mobile Broadband, I only have Wired, Wireless, Network Proxy and when I try to add ne type it only shows VPN option.

When I saw I didn't have "Mobile Broadband" in network manager I tried to reinstall it and did big mess, now my menu is very strange (I thing I didn't installed the amd64 at first and that's why it's so weird )

The USB Modem was recognised as Flash Memory and that was the problem! The only thing you have to do is this:

Disk Utility -> The USB FLASH drive(there will be 2 devices for you Model, choose the CD/DVD drive) and UnMount it!

That's it! After this wait a little bit and you're ready!

NM connections are stored in /etc/NetworkManager/system-connections/

Ubuntu – Ubuntu 13.04 recognizes usb mobile broadband modem as ethernet connection

Yes! This is one of the problems I have been facing and here is a possible solution. Looking at your lsusb output, I find the following:

Bus 002 Device 004: ID 19d2:1405 ZTE WCDMA Technologies MSM

This indicates that the Vendor ID is 0x19d2 and the Product ID is 0x1405. I would advise you the following steps:

(1) Create a bash script as follows. This bash script is to be run, everytime you would like to use your mobile modem CDMA connection. Let us suppose that the name of the bash script is `myModem.sh. Do this by typing:

sudo nano ~/myModem.sh

Type in the following lines here:

#!/bin/bash
sudo /sbin/modprobe usbserial vendor=0x19d2 product=0x1405

Save your script and exit from nano. Type:

sudo chmod +x ~/myModem.sh

(2) Run the following commands:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install wvdial 
sudo apt-get install usb-modeswitch usb-modeswitch-data

(4) Type the following:

sudo nano /etc/udev/rules.d/90-zte.rules

and type in the following line (it is a single line and no carriage returns please):

SUBSYSTEM=="block",SUBSYSTEM=="scsi",ATTRS{model}=="USB Storage 1405",ACTION=="add",RUN+="/sbin/modprobe usbserial vendor=0x19d2 product=0x1405"

Save the file and exit from nano.

(5) Now run your bash script from your home directory:

sudo ~/myModem.sh

(6) Now we have to configure wvdial.

sudo wvdialconf /etc/wvdial.conf

This will detect the modem and create a configuration file.

(7) Edit the configuration file to adjust the setting according to your country/service provider. Especially change the dialing phone number, username and password. Do this by typing

sudo nano /etc/wvdial.conf

Remove the semicolons before the phone, username and password. The semicolons tell wvdial that these lines are commented. Save your file and exit from nano.

(8) Now create your connection. Make sure you check the Connect Automatically option.

I hope this will set your modem working.
