[SOLVED] USB 3G no longer works after upgrade to GNOME 3.8

dawid.loubser · 2013-04-22 16:51:28

I did the 'big' update today, including upgrading to GNOME 3.8. Unfortunately, NetworkManager no longer picks up my 3G USB modem (which used to work fine before the update). Any pointers as to how I could debug this would be greatly appreciated.

wvdial has never really worked for me, but gnome networkmanager used to pick up my device and the connection, and now simply acts as if it's no longer present. Attempting to follow the instructions on the wiki to re-setup my USB stick (the instructions I followed in the first place) no longer works. Did today's update cause the same problem for anybody else?

**Update: After updating today to modemmanager 0.7.990-4 and running

sudo systemctl enable ModemManager
sudo systemctl start ModemManager

I have full connectivity again with the built-in DW5550 mobile broadband card in my Dell Precision M6600 (including showing signal strength in the GNOME 3.8 top bar, etc). Thanks all for the help, and (most importantly) to whoever fixed up modemmanager!

Check dmesg and journalctl when you plug in your usb 3g to see if it shows anything interesting.

Although, there have been many different problems with the gnome3.8 update. So I wouldn't be surprised if yours was related to the update as well.

The same thing happened to me after the GNOME 3.8 update.

I tried downgrading modemmanager to 0.6 as seems to work for opensuse 12.3 users (see comments at http://dominique.leuenberger.net/blog/2 … go-get-it/), but that resulted in the networkmanager icon vanishing and did not solve the problem.

I also have the problem after last update.
First I see that ModemManager was not started at startup, that was solved by this: 'systemctl enable ModemManager.service'

But when i have connected to LTE in NetworkManager there is now standing 'not enabled' and there is no signal on the icon, and the net do not work.

When I run 'nm-tool' I get this:

- Device: cdc-wdm0  [3] ---------------------------------------------------------
  Type:              Mobile Broadband (GSM)
  Driver:            qmi_wwan option1
  State:             connected
  Default:           yes

Downgrading 'modemmanager', 'networkmanager' and 'network-manager-applet' got me back online..

And when i run 'nm-tool' after downgrade, when my LTE is working, I get this:

- Device: ttyUSB0  [3] ---------------------------------------------------------
  Type:              Mobile Broadband (GSM)
  Driver:            option1
  State:             connected
  Default:           yes

wvdial might also be a workaround, if one does not like to downgrade. In my case, I had to unset my PIN on the SIM card first. One can do that using a mobile phone, for example.

Then

 # pacman -S wvdial

in /etc/wvdial.conf, I put

[Dialer Defaults]
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Modem Type = Analog Modem
ISDN = 0
Stupid Mode = 1
Dial Attempts = 3
Init1 = ATZ

[Dialer huawei]
Modem = /dev/serial/by-id/usb-ZTE_Incorporated_1_1_Surf-stick_MF19001MOD010000-if02-port0
Baud = 115200

[Dialer voda]
Init3 = AT+CGDCONT=1,"IP","web.vodafone.de"

[Dialer dial]
Phone=*99**1#
Username = umts
Password = umts

You can find out your modem name by looking it up with

ls /dev/serial/by-id/

In my case there were names containing the strings if00, if01 and if02, and if02 turned out to be the correct one. This depends on hardware.

Also, in the "Init 3" line, you may have to replace "web.vodafone.de" according to your provider. The section "dial" seems to be quite universal from what I read on the web, so you may not have to change that.

then

# wvdial huawei voda dial

and hope for the best.

Disclaimer: I do not have a comprehensive understanding of what I did here, but it worked in my case and it might work for you, too.

I noticed that the Defaults section makes a difference, because the one I just edited in above avoids some delay in dialing.

Thank you for all the informative replies so far! I wonder if we should file an upstream bug report, since several people have been affected by this? I have not been able to pin down an actual error message that illustrates the problem, it simply... doesn't work (quietly) it seems.

I'll keep trying. Quite a pity, I was just boasting to my colleagues about the smooth and easy 3G connectivity I enjoyed (compared to Mac/Linux) - now I have to eat my hat! But such are the risks of staying on the bleeding edge.

Gnome 3.8 has a couple of very annoying UI quirks that did not exist in 3.6, but that's another thread... and I like the beauty and minimalism on the whole (until I man-up and run awesome or xmonad one day).

I can also confirm the above bug on GNOME 3.8.

Modemmanager is not working.

I can connect to the internet using wvdial.

makan · 2013-04-24 14:14:20

command "systemctl disable ModemManager" can make my cdma modem appear to network manager.
but it always failed when try to dial/connect.

...back to wvdial...

Apparently reinstalling modemmanager and "systemctl enable modemmanager" has fixed my problem. Dunno why modemmanager service got disabled after upgrade. The modem connects fine as well.

Are you sure? I reinstalled modemmanager, but on

# systemctl disable modemmanager

I get

 Failed to issue method call: No such file or directory

Furthermore, there is no service named "modemmanager" listed at https://wiki.archlinux.org/index.php/Daemons_List .

My modemmanager is version 0.7.990-3.

With the new 'modemmanager 0.7.990-4' and 'network-manager-applet-0.9.8.0-3' everything works again..

sorry it's "systemctl enable ModemManager"

Case sensitive.
