3G USB Modem Not Working in 12.04
Solution 1
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. Runman 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.
Solution 3
have you tried to use usb_modeswitch:
http://wiki.ubuntuusers.de/USB_ModeSwitch
to change the type from USB MMC Storage to 3G USB Modem?
Solution 4
try
sudo modprobe usbserial vendor=0x1c9e product=0x6061
And wait for some time. It always works for me
Solution 5
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 . =)

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
andusb-devices
on two machines , one with 11.10 and the other with 12.04 :Ubuntu-11.10 :
$ lsusb Bus 002 Device 009: ID 1c9e:6061 $ usb-devices T: Bus=02 Lev=02 Prnt=02 Port=03 Cnt=01 Dev#= 9 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=3G USB Modem S: SerialNumber=000000000002 C: #Ifs= 4 Cfg#= 1 Atr=a0 MxPwr=500mA I: If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.)

Sub=ff Prot=ff Driver=option 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 ?!

Seyed Mohammad about 12 yearsWhat should happen after this command ? Should it show-up in Network-Manager ?
-
Rahul Virpara about 12 yearsyep, I hope so.

Rahul Virpara about 12 years
modprobe - program to add and remove modules from the Linux Kernel
-
Seyed Mohammad about 12 yearsI 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 about 12 yearsNo 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 about 12 yearsI 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.
