I waited some time, updated Ubuntu, kernel, BIOS/firmware and wifi router. Still have the same problems :-( Will add error report
** Description changed: If I do video conferences for example my wifi breaks down. I'm preety sure the it happens since I updated my WiFi router (FritzBox 7590 to Firmware 7.20). I was in contact with the manufacturer. They don't know any problems. I checked dmesg and saw a lot of error messages. So i thought I should report a bug here. Some times WiFi breaks down and comes up again after a few seconds, sometimes it will not come back and I have to restart the computer. Sometimes I can't even turn of WiFi in the Ubuntu menu. Settings telling me something link "network manager not available" (not sure what the exact message is). All firmware updates are installed, I updated to the latest kernel and had the problem again. The logs generated with "ubuntu-bug linux" in this ticket are with symptom "recovers after some seconds" with massive hanging of hole Ubuntu (was not able to move mouse / press strg+alt+t to open terminal). Before I learned how to generate proper logs I saved output of dmesg. I will append some of this to this ticket. There are different error messages. Some without recovering. I will append more proper generated logs (ubuntu-bug linux) to this ticket if I get similar problems and if you would like to see them. It's a ThinkPad T490, it's Ubuntu 20.04.1 LTS, it's a "Intel Corp. Intel 9560 WLAN (8086:9df0)" WiFi card. fnpk@cl003287:~$ uname -a Linux cl003287 5.4.0-48-generic #52-Ubuntu SMP Thu Sep 10 10:58:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux fnpk@cl003287:~$ fwupdmgr get-updates • Thunderbolt Controller has the latest available firmware version • Prometheus has the latest available firmware version • Prometheus IOTA Config has the latest available firmware version • SAMSUNG MZVLB512HBJQ-000L7 has no available firmware updates • System Firmware has the latest available firmware version • UEFI Device Firmware has the latest available firmware version • UEFI Device Firmware has the latest available firmware version • UEFI Device Firmware has no available firmware updates • UEFI Device Firmware has no available firmware updates ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.4.0-48-generic 5.4.0-48.52 ProcVersionSignature: Ubuntu 5.4.0-48.52-generic 5.4.60 Uname: Linux 5.4.0-48-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Thu Sep 24 09:06:55 2020 InstallationDate: Installed on 2020-01-10 (257 days ago) InstallationMedia: Ubuntu 19.10 "Eoan Ermine" -
