I have recently had trouble with wifi on my laptop. Specifically, wifi will connect but the connection is highly unstable. Downloading any file or loading more than a simple site often fails. Toggling wifi off/on restores the connection for a moment.
The problem started while I was running 21.10. I upgraded to 22.04, but the problem persisted. Eventually, I tried a clean install of 22.04. Following various posts here, I have tried numerous kernel versions. I have disabled power saving. I have tweaked modprobe settings. Unfortunately, after several reinstalls etc, I don't have all the links. But for now I'll keep the list below updated.
Edit: I am on a Dell XPS from ~2016.
