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:
0d:00.0 Network controller: Qualcomm Atheros AR9462 Wireless Network Adapter 
(rev 01)

I did a bit more digging and pulled the source from
git://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/jammy
and did a diff between -23 and -25 and search for anything related to
ath drivers, but I didn't see much there.

The only thing I did find related to wifi is about iwlwifi. There had been 
changes made to that code, specifically this from -24:
    - iwlwifi: don't advertise TWT support

I did figure out how to compile Ubuntu kernels from Git so I'll try
playing with that but I'm not terribly good at it yet. Have to figure
out how to not overwrite my current -23 kernel with the .deb it makes.
