3G USB Modem Not Working in 12.04

Question

When I connect my 3G USB Modem to my laptop with 12.04, nothing shows up in Network-Manager. This modem is working in 11.10 and the modem is shown in Network-Manager but not in 12.04 !!

Here are the outputs of lsusb and usb-devices on two machines , one with 11.10 and the other with 12.04 :

Ubuntu-11.10 :

    I:  If#= 3 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=usb-storage

Ubuntu-12.04 :

$ lsusb
    Bus 002 Device 003: ID 1c9e:6061 OMEGA TECHNOLOGY WL-72B 3.5G MODEM

$ usb-devices
    T:  Bus=02 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  3 Spd=12  MxCh= 0
    D:  Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS=64 #Cfgs=  1
    P:  Vendor=1c9e ProdID=6061 Rev=00.00
    S:  Manufacturer=Qualcomm, Incorporated
    S:  Product=USB MMC Storage
    S:  SerialNumber=000000000002
    C:  #Ifs= 1 Cfg#= 1 Atr=c0 MxPwr=100mA
    I:  If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=(none)

As the output of the above commands show, the device is detected as a modem in 11.10 but in 12.04 it is detected as a USB storage (the device is both a 3G Modem and a SD-card USB adapter).

Any help ?!

and what exactly is the problem? you'll need to provide a lot more information if you expect anybody to understand your problem. — Stefano Palazzo, Oct 20 '10 at 09:56
Is the stick recognized if you try to create a new connection under System -> Preferences -> Network Connections -> Mobile Boradband? — Bobby, Oct 20 '10 at 10:01
I always put the mobile broadband into USB port and wait for anything happen. but nothing happens. I am newbie. I apologize if you are not really understand of my question — ok comp, Oct 20 '10 at 10:36
Put the stick in and then look at the output of dmesg - please include the relevant lines in your question. — Cry Havok, Oct 20 '10 at 11:59
@ok comp: Okay, you're new, no problem with that...but did you try my advice? — Bobby, Oct 21 '10 at 20:22
@ok comp what is the make and model of your 3G device? What ISP/Telecom provider are you with? — Nick HS, Oct 24 '10 at 11:13

After a lot of searching and reading in different forums I found a solution to my problem. Please note that while the other answers didn't solve my problem, they might be helpful to others facing problems with 3G USB Modems (specially the sakis-3g script).

I found my solution in this thread, which I will detail in the following:

When connecting my USB modem, it is detected as a USB storage. According to that thread, running sudo modprobe option could make the device be detected as a modem. If not, it is also suggested to execute the following commands:

sudo su
echo 1c9e 6061 > /sys/bus/usb-serial/drivers/option1/new_id

where 1c9e 6061 is the device ID obtained from the lsusb command. This worked for my device and it was detected in Network-Manager. Note that you must become root using sudo su and running the command with sudo won't work.

To automate things, the following steps are presented:

sudo su
nano /usr/bin/usbModemScript and put the following in the file:
```
   #!/bin/bash
   echo 1c9e 6061 > /sys/bus/usb-serial/drivers/option1/new_id
```
Then save the file (Ctrl+O) and exit nano (Ctrl+X).
chmod +x /usr/bin/usbModemScript

nano /etc/udev/rules.d/option.rules and put the following in the file:

    ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="6061", RUN+="/usr/bin/usbModemScript"
    ATTRS{idVendor}=="1c9e", ATTRS{idProduct}=="6061", RUN+="/sbin/modprobe option"

Then save the file (Ctrl+O) and exit nano (Ctrl+X).

reboot

NOTE : You should replace the values 1c9e and 6061 with the appropriate device ID values of your own modem.

After reboot, your modem should be detected when connecting it to the computer. Of course, this might not be the case (as it wasn't for me)! My device wasn't detected correctly after the first time it was connected to the computer. Instead, I had to disconnect and then reconnect it, and this time it was correctly detected as a modem in the Network-Manger. Some people might also need to restart the network-manager service (as I did):

sudo service network-manager restart

================================================================================

Another potential solution is to use wvdial.

Installation: sudo apt-get install wvdial
Connect your modem to the computer.
Run: sudo wvdialconf /etc/wvdial.conf. If it says 'no modem found' then you are out of luck!
If the modem is found, run: sudo nano /etc/wvdial.conf and input your ISP information where needed by filling the fields you know about. Run man wvdial.conf in a separate terminal for information about the options. Once you are ready, save the file (Ctrl+O) and exit nano (Ctrl+X).
Now try to connect: sudo wvdial

For more information on wvdial, read the man page (i.e. man wvdial).

Hope this helps :)

I have Huawei E156 HSDPA (3G) USB Stick and I did the following, also it worked for my samsung 3g mobile via usb cable.

sudo apt-get install wvdial

after installing wvdial type following lines in terminal to edit wvdial.conf

sudo gedit /etc/wvdial.conf

Paste into your editor, the following lines:

[Dialer name]
Modem Type = Analog Modem
Phone = *99#
ISDN = 0
Baud = 460800
Username = " "
Password = " "
Modem = /dev/ttyUSB0
Init1 = ATZ
Init2 = at+cgdcont=1,"ip","your Access Point Name"
Stupid Mode = 1

Whenever you have to connect just type in your terminal

sudo wvdial name

Now you will be online with blazing speeds. I think this method is less time consuming and faster than other methods.

What should happen after this command ? Should it show-up in Network-Manager ? – Seyed Mohammad May 30 '12 at 05:32
yep, I hope so. – Rahul Virpara May 30 '12 at 05:43
modprobe - program to add and remove modules from the Linux Kernel – Rahul Virpara May 30 '12 at 05:47
Unfortunately this command didn't solve the problem and still there is no Mobile Broadband connection in my Network-Manager. Thanks for helping anyway. – Seyed Mohammad May 30 '12 at 06:04
@SeyedMohammad Normally this command also did not work for when modem was attached. 1. Remove dongle. 2 Run this command here product should be Target 3. Insert modem. – d a i s y Jan 30 '17 at 11:37

have you tried to use usb_modeswitch:

to change the type from USB MMC Storage to 3G USB Modem?

I assumed that UsbModeSwitch is a pre-installed module on modern Linux dirtros! Anyway I found another way to switch the device type, which I will fully explain as an answer. – Seyed Mohammad Jun 06 '12 at 06:05

Did you install usb-modeswitch ? Ubuntu 10.10 must have come along with it . Try to check with Synaptics whether usb-modeswitch is installed . Once installed , plug in your USB modem and wait . There will be an option at the connectivity icon where it writes create new mobile broadband . Then follow the steps from the window . Im using usb modem with Ubuntu 10.10 and it runs fine . =)

For this USB MODEM, try sakis-3g. You can download it: http://www.sakis3g.org/#downloading

No I haven't tried that script. I was hoping there would be a standard solution to the problem, specially since the device works fine with the previous version of Ubuntu (i.e. 11.10). – Seyed Mohammad Jun 06 '12 at 05:57

Just, use alternative connection, full update ubuntu. Connect again using your 3g Dongel.

And it will work fine!

I always keep my Ubuntu installation up-to-date (every-day), but unfortunately that didn't make my modem show-up in Network-Manager. – Seyed Mohammad Jun 06 '12 at 05:55

Do you know what brand and model your modem is? Huawei, Option or Sony Ericsson? Some Huawei models need some tweaking. At the danish site here: http://scripts.linux.dk/joomla/index.php/mobilt-bredb%C3%A5nd/mobiltbredbans.html you can download and run a script that will make most Huawei models work. You can translate the page with google translate ;-)

I used Huawei once, for the usb-modeswitch, it srill cannot work, because nothing still happen, even my mobile broadband modem didn't being detected. just the lights of my broadband keep blinking – ok comp Oct 26 '10 at 05:21
I also already download http://scripts.linux.dk/joomla/index.php/mobilt-bredb%C3%A5nd/mobiltbredbans.html the following link, but the result still the same – ok comp Oct 26 '10 at 05:22

install usb-modeswitch and use wvdial or gnome-ppp to connect to internet. You will also be able to connect using network manager if your modem is detected. usb-modeswitch is the trick.

If your modem has custom drivers available then install them.
