Auto connect to 3G network only works after manually enabling mobile broadband after modem inserted/bootup/resume

[Anders Feder]

NetworkManager does not connect to my 3G provider at login, even though it is configured for automatic connection.

What I expect:
- When selecting the option "connect automatically" in the network-setting for a mobile connection, it should connect automatically, like it has until Ubuntu 11.04.

What happens:
- When I plug in the modem (USB; e.g. "UMTS-Stick"), it appears as available connection, but does not connect;

For what it is worth, this the debug output from modem-manager at startup.

[Mathieu Trudel-Lapierre (mathieu-tl)]

AFAIK, autoconnection for mobile broadband is not yet supported.

Marking Wishlist/Confirmed. Some work will be needed there.

Same here but also when I resume the computer after suspend.

[Russell Faull (rfaull)]

This is a kinda annoying bug in 11.10. If my connection drops-out (fairly regular event), I can't reconnect without a reboot. I have tried sudo killall modem-manager (worked in 11.04), disable networking and sudo restart network-manager without effect. Am I missing something? Is there an easy workaround? Can I downgrade network manager or other package?

[Russell Faull (rfaull)]

I tried sudo restart modemmanager and that seems to work after waiting 30 seconds or so.

I wonder, though, if there is a dropout, why does this process not get automatically triggered if auto connection is set in network manager?

[Angelos Vlassopoulos (avlass)]

What I do is put the computer to sleep (suspend) and then when it wakes up everything is ok.

[Anders Feder (afeder)]

Russell, your issue seems unrelated to autoconnection. You may want to file a separate bug report.

[Russell Faull (rfaull)]

Anders, thanks for your help. I have filed bug report at LP#905622

[Zane Zakraisek (doublezane)]

Is this the kind of bug to get fixed in 12.04, or is this looked at as a pretty low priority? This bug is getting pretty annoying. I leave my computer on 24/7 now connected to mobile broadband. Every day the connection drops and I have to go into Netowrk Manager and disable/reenable Mobile Broadband and dial in again. PLEASE FIX THIS!!!

[Zane Zakraisek (doublezane)]

Can someone please fix this????

[Thomas Hood (jdthood)]

Hey yo, Bug Watcher, it's not "Invalid" upstream. The linked report is a duplicate of upstream #554538 which still has status NEW.

[Marius B. Kotsbak (mariusko)]

Updated to correct upstream bug report.

[Vladimir Dobriakov (vladimir-geekq)]

If the bug is really annoying for you and you can not wait for a proper fix, you can use a full automation workaround (bit complicated) http://www.thefanclub.co.za/how-to/how-auto-connect-ubuntu-1204-gsm-mobile-broadband-connection-on-boot-startup-service#version2

I decided for a less complicated workaround creating a script

    #!/bin/bash
    nmcli -t con up id "simyo"

Note: "simyo" is the name of my GSM/UMTS provider and the name of the connection in the NetworkManager. See `man nmcli` for documentation.

Then I bound that simple script to a keyboard shortcut (WindowsKey+F5).

Hi Marius, this worked for me on 12.04. Have got to next release yet

Japp, it still works as a workaround, but we should have a proper implementation of something like this.

More precisely, a user friendly GUI implementation.

-- rpr.

[Shannon Black (shannon-netforge)]

nah, if it needs an extended GUI then its still a bug .. needs to work like a built in connection of the dialog needs to be adjusted.. not too sure why it worked OOTB in 10.10 but if it worked in a previous version its a regression that can be remedied? :)

[TheHobbit (the-hobbit)]

Thr attached script is a work around (tested on 12.04LTS) put into /etc/init.d as mm_monitor and execute
$ sudo uptate-rc.d mm_monitor defaults

The script run as a daemon ensuring that nmcli nm wwan on is called whenever modem manager adds a device. Beside solving the bug as described it also ensure that auto-connect system-accessible WWAN devices are connected on startup (which was my original problem)

Hoping it helps

[Mark Wentland (wentland)]

The problem with 3G network support is not only in autoconnection but also in auto reconnection as described in
https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1158442
Kind Regards

[Marius B. Kotsbak (mariusko)]

There is some code upstream that I am testing now that probably solves this problem, and possibly the reconnection issue too.

[Leonardo Borda (lborda)]

@mariusko

Hi, did you have a chance to test the upstream patch ?

Leonardo

[Rafał Rzepecki (divided-mind)]

I actually tracked it down to ModemManager initially having any modem disabled (and NetworkManager just reflects this state, and can manipulate it). `mmcli -e` enabled a modem and also causes the NetworkManager to connect, which confirms this. So the right solution would be to somehow persuade ModemManager to enable modem by default.

[Marius B. Kotsbak (mariusko)]

Yes, upstream patch works, but for me it did not work after sleep of laptop.

[K Sriram (sriramkannan95)]

Simplest solution to this problem:

open with root permission:
sudo gedit /etc/rc.local

Now add this line above exit 0

(while :; do nmcli -t nm wwan on; sleep 1; done)&

Save the file and exit.

This is the best solution i have tried, it works in all situations.
