@MikeR:
Thanks. I downloaded the missing bin files as you explained in #7 and get rid
of the errors.
However, my wifi was NOT coming back under kernel 5.11.x (still worked fine
when booting 5.8.x)
In my case (Broadcom BCM4313 802.11ac), I had to install a different
(backported) version of the bcmwl-kernel-source package, see
