Ok, I figured out kernel compiling. And many git bisects later, I think I found the commit causing the issue. It's commit 4eb4bb735a536d922fc92de347b90ea290067c71 that causes my WiFi to become unstable. If I go one commit earlier (ef8f38d37265d79607e1fc132e28fadec8f51056) it all works perfectly, using that right now.
The commit causing breakage is a pretty short patch, but I don't really understand what it does: https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/jammy/commit/?h=master-next&id=4eb4bb735a536d922fc92de347b90ea290067c71 I hope this helps at least! -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1968391 Title: Unreliable wifi with loads of CTRL-EVENT-BEACON-LOSS Status in linux package in Ubuntu: Confirmed Bug description: Using the current beta of Jammy, I no longer have stable WiFi after April 5, 2022 update of wpasupplicant from 2:2.10-2 to 2:2.10-6. There is a chance it may also be related to network-manager going from 1.36.4-1ubuntu1 to 1.36.4-2ubuntu1, but the logs seems to point to wpasupplicant (see below) Wifi is stable often, but also often it fails to load webpages intermittently or fails to download the packages using apt for example, so it's not browser related.
