Public bug reported: When trying to connect through wifi it keeps disconnecting and trying to connect again. The output from dmesg shows repeatedly:

This seems to happen only when connecting to a particular router, a vodafone EasyBox (which worked fine before updating to ubuntu 19.04) connecting to some other router seems to not have this problem ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: network-manager 1.15.2-0ubuntu2 ProcVersionSignature: Ubuntu 5.0.0-8.9-generic 5.0.1 Uname: Linux 5.0.0-8-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.20.10-0ubuntu23 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Apr 1 11:30:05 2019 IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback InstallationDate: Installed on 2018-12-10 (111 days ago) InstallationMedia: Ubuntu 18.10 "Cosmic Cuttlefish" - Release amd64 (20181017.3) IpRoute: default via 192.168.42.129 dev enp0s20u9 proto dhcp metric 100 169.254.0.0/16 dev enp0s20u9 scope link metric 1000 192.168.42.0/24 dev enp0s20u9 proto kernel scope link src 192.168.42.112 metric 100 NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true SourcePackage: network-manager UpgradeStatus: Upgraded to disco on 2019-03-31 (0 days ago) nmcli-nm: RUNNING VERSION STATE STARTUP CONNECTIVITY NETWORKING WIFI-HW WIFI WWAN-HW WWAN running 1.15.2 connected started full enabled enabled enabled enabled enabled ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug disco -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1822565 Title: Wireless network immediately disconnects after updating to 19.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1822565/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
