Something's wrong with scan after resume. Not sure if it's NM or kernel bug, but doing 'sudo iw wlan0 scan' fixes the issue till next suspend/resume.

In the networking tray drop-down I can see one single wifi network listed (out of the many within range), and it can't reconnect to my network. I clear it with the hammer of: sudo rmmod iwldvm && sudo modprobe iwldvm I'm not sure what would be more appropriate, but that works. Then my laptop auto-connects to the right network, as expected. Turning on/off the hardware wireless switch on the thinkpad does not clear the problem. Just before running ubuntu-bug to submit this, I had the problem, then reloaded the iwldvm module. ---- ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-22-generic 4.4.0-22.40 ProcVersionSignature: Ubuntu 4.4.0-22.40-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: james 1934 F.... pulseaudio CurrentDesktop: Unity Date: Thu Jun 9 18:57:10 2016 EcryptfsInUse: Yes InstallationDate: Installed on 2016-05-21 (19 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) MachineType: LENOVO 2325KZ5 ProcFB: 0 inteldrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.4.0-22-generic root=UUID=72122534-7dd5-411b-9c56-c4844502e0ad ro quiet splash vt.handoff=7 RelatedPackageVersions: linux-restricted-modules-4.4.0-22-generic N/A linux-backports-modules-4.4.0-22-generic N/A linux-firmware 1.157 SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 03/05/2013 dmi.bios.vendor: LENOVO dmi.bios.version: G2ETA0WW (2.60 ) dmi.board.asset.tag: Not Available dmi.board.name: 2325KZ5 dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.asset.tag: 518896 dmi.chassis.type: 10 dmi.chassis.vendor: LENOVO dmi.chassis.version: Not Available dmi.modalias: dmi:bvnLENOVO:bvrG2ETA0WW(2.60):bd03/05/2013:svnLENOVO:pn2325KZ5:pvrThinkPadX230:rvnLENOVO:rn2325KZ5:rvrNotDefined:cvnLENOVO:ct10:cvrNotAvailable: dmi.product.name: 2325KZ5 dmi.product.version: ThinkPad X230 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1590985/+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
