Mobile Broadband must be enabled after every power on, suspend, hibernate, or signal loss

Status changed to 'Confirmed' because the bug affects multiple users.

This is also confirmed for Lubuntu, since it also uses network-manager

Chris

I saw an update for network manager was available last night, so I re-installed Ubuntu 11.10 in the hope that it would work better. It did not. Even though the Mobile Broadband configuration is set to connect automatically it has to be manually re-connected at every power-on, resume from suspend or hibernation, or after the signal is lost or dropped.

Mobile broadband does not yet connect automatically; that's just not supported yet (although someone is working on a patch for this). What exactly do you mean by "must be enabled"? Is it just that the connection needs to be clicked on to activate it, or do you need to take other steps?

Hi, thanks for looking. I mean that after every power on or resume I have to open the drop-down for network manager and click on "enable mobile broadband". Because I have "connect automatically" enabled in the connection configuration it will then connect.

If the signal is lost because I travel through a poor signal area, I also have to click on "enable mobile broadband" again, however there appears to be another bug that sometimes stops network-manager from negotiating with the home network - I've been powering off the netbook and turning it back on to get a connection. This occurs at least half the time.

It used to work fine in 10.04 LTS - the 3G connection would be automatically re-established no matter what.

Mathieu Trudel-Lapierre it was work in 10.04 and 10.10. autoconnect. so its just broked on 11.10 somehow

Agreed, as stated in the original problem report above it works very well in 10.04 LTS, to which I have reverted. The problems started with 11.04 and can make mobile computing quite frustrating.

I will be testing the Alpha of 12.04 Precise when I get time, but I expect it is currently using the same version of Network-Manager.

Chris

This problem is confirmed for 12.04 Alpha 1. The version of NetworkManager that is installed is current (0.9.3.0) and all updates have been done (none held back).

The version of NetworkManager that works well in 10.04 LTS appears to be 0.8.0 based on the format of the deb file ie.
network-manager_0.8-0ubuntu3.2_i386.deb
(NB this older version does not have the --version switch so I'm unsure how to verify this)
By "works well" I mean it behaves as you would expect - if Mobile Broadband had been enabled previously it returns to that state when you resume from a suspend or hibernate, or when you power on. If the signal is lost because you pass through a 3G Blackspot it re-connects as soon as it gets a signal.

I'm unsure how I can get this bug moving from "incomplete" and of "low" importance to something that will be looked at. It would be nice if we could have this working for the LTS release because at the moment moment computing with current releases is a fail.

Chris (Off to look at the Gnome NetworkManager project website)

As per the project website I've reported it in bugzilla:
https://bugzilla.gnome.org/show_bug.cgi?id=667488

If someone having this trouble could add details in that report and add a confirmation please...

Chris

This bug is still confirmed for NetworkManager 0.9.4.0 in Ubuntu 12.04

Chris

Same here! Time consuming (click and wait, click and wait.. nothing.. reboot..click and wait)!

Duplicate of bug #848164.

We're seeing some activity for this in the upstream bug report on bugzilla:

https://bugzilla.gnome.org/show_bug.cgi?id=667488

There's a patch listed which I am yet to try (trying to find time) and hopefully we'll see a proper update fix for this at some point.
