I have the same card in an HP EliteBook 8570p with FreeBSD 14.0-CURRENT (and for a long time, I used it with 13.0-CURRENT).
(Networking is occasionally quirky for me, but not only with Wi-Fi; sometimes also with a wired connection. Quirky, but maybe a peculiarity of my chosen configuration. I might post something more to https://lists.freebsd.org/archives/freebsd-wireless/2022-September/ in due course (ignore the thread that I began on 11th September.)
Gut feeling, after years of using this hardware: the initial non-find of a network, at installation time, in your case, might have been a one-off. If, however, you find it reproducible: I'll be interested to see (or help you make) a bug report in Bugzilla.
