Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?
Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.19 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

But it only works if the hardware switch for WLAN is enabled - thus at the moment the internal WLAN interface and the external need to be on to make it work. Unfortunately (as reported in bug 1385059) this means that the internal interface is sucking up my battery when it tries to connect without success. My expected behaviour would be to disable the internal WLAN via hardware switch and be able to plugin my USB WLAN dongle. I've attached lsmod-output with WLAN enabled (USB dongle working perfectly, while internal WLAN hardware is constantly scanning for networks) and after disabling the internal WLAN. $ lsb_release -rd Description: Ubuntu 14.10 Release: 14.10 --- ApportVersion: 2.14.7-0ubuntu8.1 Architecture: i386 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: hirsch 2675 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.10 EcryptfsInUse: Yes HibernationDevice: RESUME=UUID=cef59770-4af9-4efd-b1a8-f3b9e6fdf30f InstallationDate: Installed on 2013-01-14 (763 days ago) InstallationMedia: Ubuntu 12.10 "Quantal Quetzal" - Release i386 (20121017.2) MachineType: LENOVO 40684KG NonfreeKernelModules: wl Package: linux (not installed) ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-30-generic root=UUID=57ea19ce-b54f-4b7c-975c-b11064321210 ro quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 3.16.0-30.40-generic 3.16.7-ckt3 RelatedPackageVersions: linux-restricted-modules-3.16.0-30-generic N/A linux-backports-modules-3.16.0-30-generic N/A linux-firmware 1.138.1 Tags: utopic Uname: Linux 3.16.0-30-generic i686 UpgradeStatus: Upgraded to utopic on 2014-10-23 (116 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 10/11/2010 dmi.bios.vendor: LENOVO dmi.bios.version: 14CNA0WW dmi.board.name: Kuril dmi.board.vendor: Lenovo dmi.board.version: Rev 1.0 dmi.chassis.asset.tag: No Asset Tag dmi.chassis.type: 10 dmi.chassis.vendor: Lenovo dmi.chassis.version: Rev 1.0 dmi.modalias: dmi:bvnLENOVO:bvr14CNA0WW:bd10/11/2010:svnLENOVO:pn40684KG:pvrLenovo:rvnLenovo:rnKuril:rvrRev1.0:cvnLenovo:ct10:cvrRev1.0: dmi.product.name: 40684KG dmi.product.version: Lenovo dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1422513/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
