Description Andreas Ritter 2011-03-09 11:14:17 UTC
User-Agent:       Mozilla/5.0 (X11; Linux x86_64; rv:2.0b12) Gecko/20110222 Firefox/4.0b12

affects OpenSuse 11.4 RC2 and Final:
I have two different Huawei USB UMTS-Modems, which both have the same issues. A connection with a PCMCIA-Modem works alright.

System: x86-64 and i586, kde4, kde-networkmanager (plasmoid and normal kde4-version)

Both USB-Modem worked very well with OpenSuse 11.3 Final and same network-managerprofiles, so it must be a software-related bug in OpenSuse 11.4.

Problem appears with both Huawei USB-Modems, an older Model (E160) and a newer one (E1750), both have this SD-Card Slot, but I don't use that.

Could be connected somehow to this Bug: https://bugzilla.novell.com/show_bug.cgi?id=668838
But as I wrote: Everything works fine with OpenSuse 11.3

Reproducible: Always

Steps to Reproduce:
1. Connect USB-Modem to USB Port.
2. The mobile-phone icon appears in Network-Manager.
3. Click on a profile to connect with.
4. "Setting up connection"...
5. After a few seconds the modem-icon disappears, after a few more seconds it appears again (unconnected of cause, then reproduceable from step 3)


Expected Results:  
Connect to the internet :-)

Put USB-Modem in Port:

Comment 1 Mark Draheim 2011-03-17 12:48:02 UTC
same problem here and other bugs looks like dups but since this one is marked P1 I add comments here. This is a showstopper on mobile computers and a fixed update should be provided ASAP.

likely dups:

https://bugzilla.novell.com/show_bug.cgi?id=561706

The problem is apparently with PIN unlocking. Knetworkmanager fails, Gnome NM applet apparently can do it after a series of ping-pong with root authentication dialogs - but then cannot establish connection. I now start GnomeNM, enter PIN, kill the applet, and start knetworkmanager. It's the only way I found to get a connection via UMTS on 11.4

The advice in one of the above bugs to install provider info did not help at all and I don't see how this could help anyway since I know the APN and other provider info and it is already stored with NM.

It worked fine in 11.3, so this is a major regression.

Running command line nm I get the error that the device is not compatible with the connection.
Comment 2 Andreas Ritter 2011-03-17 13:00:41 UTC
I tested both modems with Opensuse 11.3 with updated kde 4.6.1, so as this one works, it can't be only a problem with knetworkmanager.

And: A PCMCIA-Modem works alright with 11.4. So I thought the problem is somewhere in usbmodeswitch...
Comment 3 Mark Draheim 2011-03-17 15:16:42 UTC
I thought so, too, because of the "device is incompatible" error of console nm. Right now I am connected via the USB stick, so I can't post any output. But I happily provide any output needed to debug the problem. Will start tomorrow. BTW, I have a Huawei E160 USB Stick.
Comment 4 Mark Draheim 2011-03-17 20:10:31 UTC
okay, Gnome nm-applet (NetworkManager-gnome) works, though I do not understand what it needs the root password for. Knetworkmanager definitely does not work unless PIN is unlocked outside knetworkmanager. Even then the configured UMTS connections are not shown in the plasmoid, one has to open the "manage connections" dialog and set the UMTS connection to "auto connect".

The modem cannot return -108. Something is very fishy. Can you provide the output of modem-manager with --debug ?
Comment 9 Dirk Waldeck 2011-04-27 08:49:18 UTC
Same with my Dell Studio 1558
Comment 10 Jan Ritzerfeld 2011-05-28 15:57:28 UTC
I did nothing besides regular updates and, now, I can establish a WWAN connection with KDE although my SIM has a PIN set. Anyone else tried with 11.4 updated?
