Related to Getting HUAWEI Mobile Broadband E173 to work in Ubuntu 13.10 . I have the same situation with the huawei ec156 modem .With wvdial it works perfectly with /dev/ttyUSB0 but with Network manager for some reason it uses /dev/ttyUSB2 and fails to connect (even though it is detected by NW manager ) . May be it is as case of way the code/config is implemented. I would really like to use the Network manager for easier connectivity and to use the data card as a Wifi hotspot using network sharing .

This device has support for additional SIM hence ttyUSB2 & ttyUSB0 is CDMA

I have tried the solution here configuring USB modem( Huawei EC156) in ubuntu 13.10 also .

Question is "Can I manually configure Network manager to use ttyUSB0 instead of ttyUSB2"

May be one work around would be to give some options to specify the correct modem and the AT commands just like a normal dialer .

Install following packages sudo apt-get install python-pysqlite2 python-pysqlite2-doc python-pysqlite2-dbg hal python-messaging wader-core –  user224082 May 23 at 13:30
    
Im not sure what that has to do with usb_modeswitch and usb modem . If you are suggesting some steps ; can you list out all the steps ? –  windy_rider May 23 at 15:45

1 Answer 1

It has been identified as wireless data modem mode by the computer. So it is needed to swithch that mode to mobile broadband mode. That mode switch is done by the package usb-modeswith. Confirm weather usb-modeswitch is been installed by:

dpkg --get-selections | grep -v deinstall

This will list the installed packages. See weather usb-modeswitch is thers.(Go through the alphebatical order)

If it present, then try with install the all the packages that Huawei Broadband Modems need to function properly.

sudo apt-get install python-pysqlite2 python-pysqlite2-doc python-pysqlite2-dbg hal python-messaging wader-core

Then also install all the packages that network-manager needs to work properly. (Its dependencies)

sudo apt-get install multiarch-support dbus dnsmasq-base iproute2 iputils-arping isc-dhcp-client libc6 libdbus-1-3 libdbus-glib-1-2 libglib2.0-0 libgudev-1.0-0 libmm-glib0 libnl-3-200 libnl-genl-3-200 libnl-route-3-200 libnm-glib4 libnm-util2 libpolkit-gobject-1-0 libsoup2.4-1 libsystemd-login0 lsb-base policykit-1sysv-rc  udev wpasupplicant

I see "usb_modeswitch" binary already pre-installed with 14.04 . network-manager is also pre-installed . I have tested with another Huawei make (different model) dongle provided another carrier . And network manager works flawlessly . –  windy_rider May 24 at 11:55
    
Model of other working Huawei modem is E1731 –  windy_rider May 24 at 12:07

No luck with that approach . Actually Network manager detects the device and I can see the device listed in the Network Connection dialogs . If you notice the logs usb mode switch also happens . It seems to be picking /dev/ttyUSB2 instead of /dev/ttyUSB0 . –  windy_rider May 24 at 17:15
