Networkmanager: mobile broadband doesn't work anymore

thesofty · 2011-05-10 23:08:52

Hi,

I had setup a mobile broadband connection for my Nokia N900, connected via USB, with the NetworkManager (Gmome 3) two or three weeks ago. It worked perfect. Yeserday I tried the internet connection again - after a couple of rolling updates (e.g. actual NetworkManager 0.8.999-1). Now, the internet connection doesn't work anymore.

NetworkManager --no-daemon prints out the following:

NetworkManager[2944]: <info> Activation (ttyACM0) starting connection 'n900'
NetworkManager[2944]: <info> (ttyACM0): device state change: disconnected -> prepare (reason 'none') [30 40 0]
NetworkManager[2944]: <info> Activation (ttyACM0) Stage 1 of 5 (Device Prepare) scheduled...
NetworkManager[2944]: <info> Activation (ttyACM0) Stage 1 of 5 (Device Prepare) started...
NetworkManager[2944]: <info> Activation (ttyACM0) Stage 1 of 5 (Device Prepare) complete.
NetworkManager[2944]: <warn> GSM modem enable failed: (32) Serial command timed out
NetworkManager[2944]: <info> (ttyACM0): device state change: prepare -> failed (reason 'modem-init-failed') [40 120 28]
NetworkManager[2944]: <warn> Activation (ttyACM0) failed.
NetworkManager[2944]: <info> (ttyACM0): device state change: failed -> disconnected (reason 'none') [120 30 0]
NetworkManager[2944]: <info> (ttyACM0): deactivating device (reason: 0).

It seems, the modem cannot be initialized

Using wvdial with the N900, the internet connection works still fine.

What is the problem? Any ideas?

check the networkmanager bug tracker - lots of bugs getting reported and fixed nowadays...

I'm having the same problem

mits · 2011-05-13 07:52:54

Same problem here ZTE MF110 Modem (up to date kde&networkmanagement+kdeplasma-aplets-networkmanagement)

mits · 2011-05-13 08:46:08

For me is solved by installing network-manager-applet instead kdeplasma-applets-networkmanagement.

hellwalker · 2011-05-13 19:45:42

i got the same problem with kdeplasma-applet-networkmanager, and solved use gnome-nm

fijam · 2011-05-13 21:19:21

I am experiencing the same problem with current [testing] stack and gnome 3. My Option GT Globetrotter used to work just fine, now networkmanager gets stuck at Serial command timed out.

I'm having the same problem here https://bbs.archlinux.org/viewtopic.php?id=118886. However, I can't seem to fix it by downgrading either networkmanager or nm-applet.

thesofty · 2011-05-14 06:42:48

Exactly the same to me:
Neither downgrading network-manager-applet, nor networkmanager fixes the problem. For me, the only way to get my mobile running as an internet modem is using the good old wvdial.

In my attempts to get wvdial configured and working I had to create the directory /var/lock which got wvdial up and running but also seems to have fixed my connection through nm-applet. More details - https://bbs.archlinux.org/viewtopic.php?id=118886.

Hi,
I managed to solve. Only the downgrade did not work. My solution:

1-Create the directory (if not existing)
/var/lock

2-Do not use package:
kdeplama-network-management

3-Use the package (downgrade)
extra/modemmanager 0.4-1 [instalado: 0.4-1]
http://arm.konnichi.com/2011/04/30/extr … pkg.tar.xz

4-Use the pachage (gnome)
network-manager-applet

5-Add dbus policy (If the file nm-applet.conf does not exist, create!)

Hi. I just installed previous version of modemmanager. That did it.
I'm on LXDE+openbox + nm-applet.

Did anyone bother filing a bug yet?

spark666 · 2011-05-24 13:45:46

i had a n900 to in my opinion the best phone ever.better install to your phone Wifi Hotspot application,and try to conect as a wireless router.maybe it will work:)

ilpianista · 2011-05-24 17:53:17

good news about the KDE plasmoid!
With both kdebase-workspace 4.6.3-2 and kdeplasma-applets-networkmanagement 1:git20110524-1 wireless networks and 3G modems work again with NM09.

Mobile broadband stopped working again.
I'm using Nokia N900 as usb modem.
