After fresh install of Ubuntu 18.04.1 wifi and network work flawlessly but after routine kernel update (from 4.15.0-29.31 to 4.15.0-34.37) network manager correctly show wireless networks but cannot establish a connection. Rebooting with previous kernel (4.15.0-29) fix the problem and I had to set it as default in grub. Please find attached the report obtained running ubuntu-bug linux after booting the latest kernel. Bug symptoms look similar to those described for bug 1788997 but as far as I understand they do not seem related. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: mauro 1447 F.... pulseaudio /dev/snd/controlC0: mauro 1447 F.... pulseaudio CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=5f99e622-4108-4ba0-88ab-fd8f80e7e47d InstallationDate: Installed on 2018-09-15 (1 days ago) InstallationMedia: Ubuntu 18.04.1 LTS "Bionic Beaver" - Release amd64 (20180725) MachineType: Dell Inc.
