Oh, you are right. I booted into the 5.15.0-23-generic kernel and the WiFi instability went away. I've been using it for a few hours now and I would have seen the issue by now. I checked the logs and the update to 5.15.0-25-generic was installed on 6 April, 2022 which correlates roughly when I started having issues.
I suppose this means I filed this bug against the wrong package. Should I do something about that? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1968391 Title: Unreliable wifi with loads of CTRL-EVENT-BEACON-LOSS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/wpa/+bug/1968391/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
