NetworkManager does not recognise Modem 3g

Postby walsen » Mon Nov 04, 2013 1:55

Hi,

I had a big fight with my modem 3g to make it work two days ago, after making it using usb_modeswitch I hibernated my machine, when I restarted the session the modem stopped being recognized by NetworkManager again, this time it seems it's not related to usb_modeswitch. I have got the following when I query the modem manager status:

Code: Select all
[email protected] ~ $ sudsystemctl status ModemManager.service
ModemManager.service - Modem Manager

Googleing a bit I found this issue on the Gentoo's forum: http://forums.gentoo.org/viewtopic-t-94 ... art-0.html

I don't really know it it's the same issue. Do you have any thoughts about this problem, I would really appreciate any help.

Thanks.

There have been a couple of threads about this issue which is still ongoing
My modem Huawei E353 can only be activated every time with usb_modeswitch
This occurs both on systemD and sysvinit
I dont have this problem on Arch with systemD

Has anyone solved it?
