Google brought me to Linux Wireless. The regulatory database contains all
national regulations about WiFi signals and can be downloaded form that site.
The site also hosts crda (Central Regulatory Domain Agent) and the following
can be found in the README of that package:
CRDA is no longer needed as of kernel v4.15 since commit 007f6c5e6eb45
("cfg80211: support loading regulatory database as firmware file") added
support to use the kernel's firmware request API which looks for the
firmware on /lib/firmware. Because of this CRDA is legacy software for
older kernels. It will continue to be maintained.
My kernel is 4.15.7, so this may explain the error line in kern.log.
The problem is solved by downloading wireless-regdb (no install needed) and
copying reg* to /lib/firmware.
