"horrible mess" doesn't describe an actual problem.
"almost unusable" doesn't say "why?"

Likely iwlwiifi will not be any better as is iwm(4) at this point;
porbbaly for different reasons.

What does `man iwlwifi` say on your system on how to load iwlwifi
currently?


As a note, as the above will change in the next days for stable/13:

given you have a card also supported by iwm(4), you probably want to
have a look at devmatch_blocklist=".." in rc.conf[.local] to avoid
loading that.

In HEAD iwlwifi(4) will auto-load, but iwm(4) will stay preferred over iwlwifi(4)
if your device is supported by iwm(4) and that change will come to stable/13
as well.
