Bug Description
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.
