<https://www.freebsd.org/cgi/man.cgi?query=wlandebug&sektion=8&manpath=FreeBSD#SEE_ALSO> includes a link to four manual pages, three of which are not available: > athdebug(8), athstats(8), ifconfig(8), wlanstats(8) (ifconfig(8) is available.)
In the absence of a manual page, random success with an imaginary option: wlanstats help – does not present help, but does present useful output. <https://forums.freebsd.org/posts/563691>
