Ok, yeah, this seems to be the case. Just on a whim, by dropping the
iwlwifi-ty-a0-gf-a0-86.ucode blob with the rest of the firmwares, Linux
sill loads the older 83 version. So presumably this is evidence that
indeed the kernel does have a maximum version that it'll attempt to load.
It is possible the 6.5 kernel

Yeah, it might be an option. Though TBH, this is Ubuntu 22.04 with the
updated HWE kernel. I played briefly with the mainline
<https://github.com/bkw777/mainline> package for installing Ubuntu
mainline kernel builds. And while it did install 6.7 OK, it put
packages in a weird state because the kernel package was built on a
system that had a newer version of libc than what 22.04 provides. So I
pretty quickly jettisoned that idea.
I also briefly played with a Broadcom Wi-Fi adapter that I happened to
have around and that was a complete nightmare in and of itself that I
gave up on before getting it completely working.
For now, I've got some iwlwifi module options set to see if they help:
options iwlmvm power_scheme=1
options iwlwifi bt_coex_active=0
But I probably won't be confident that it's had an effect for a week
maybe. I've also heard that the ALFA AWUS036AXML is also an option that
"just works" and well at that, while also supporting Wi-Fi 6E, FWIW.
Failing any of that, I suppose when Ubuntu 24.04 is released, maybe the
kernel is new enough to avoid most of this trouble. It's just
disappointing to see how much of a wild west the whole concept as
rudimentary as "working wifi" is in the land of Linux in the year 2024. :-/
