[Solved] Sierra Wireless 3G Modem stopped working after upgrading

I have a Fujitsu Lifebook E751vPro with an integrated 3G USB Modem. This used to work flawlessly with kde, networkmanager, modemmanager and kdeplasma-applets-networkmanagement. Now I upgraded my laptop with pacman -Syu and mobile broadband connections don't show up anymore in kdeplasma-applets-networkmanagement. I have all testing repos enabled.

installed:
kdeplasma-applets-networkmanagement 1:0.9.0.2-1
networkmanager 0.9.4.0-6
networkmanager-dispatcher-openntpd 1.0-3
networkmanager-dispatcher-sshd 1.0-2
networkmanager-openvpn 0.9.4.0-1
modemmanager 0.5.2.0-2
mobile-broadband-provider-info 20120614-1

So the modem seems to be recognized and initialized. But why Qualcomm??

Again: this configuration worked before. Any clues?

Re: [Solved] Sierra Wireless 3G Modem stopped working after upgrading

I fear this is a kernel bug. They added some lost IDs back in 3.4.3, but they seem to have missed mine...

http://www.kernel.org/pub/linux/kernel/ … eLog-3.4.3

commit a06d0d26d87cc397e11e75f6c1fc54d191bf60ef
Author: Bjørn Mork <bjorn@mork.no>
Date:   Tue Jun 5 21:18:10 2012 +0000

    net: sierra_net: device IDs for Aircard 320U++
   
    commit dd03cff23d694cfb0fdae80cb618e7ced05ea696 upstream.
   
    Adding device IDs for Aircard 320U and two other devices
    found in the out-of-tree version of this driver.

how can I verify this guess?

Since nobody seems to have an idea I filed a bug report

Re: [Solved] Sierra Wireless 3G Modem stopped working after upgrading

Solved. See bug report for further information. You can circumvent this for now by blacklisting module qmi_wwan which gets bound to the third modem interface accidently. Hopefully the fix is in the next kernel release.

Marking this as solved - well, sort of. wink
