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,
Version 5.15.0-23-generic still works great for me, no dropping WiFi at
all. Version 5.15.0-25-generic is where the troubles started. Version
5.15.0-27 from the updates this morning has the same issues.
For completeness sake, my output of lspci for the wireless card:

This is affecting me as well after an upgrade to 22.04 (Ubuntu Mate.)
Previous install, fully-patched 20.04, was rock solid. Now I am lucky if

house runs on wifi -- sadly, no hardwired options. All other
computers/phones have no

I was runing Ubuntu 20.10, 21.04 up to Ubuntu 21.10 with Kernel 5.13.0
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
try boot kernel 5.15.0-23-generic
