Small correction: the AX211 card in the Framework 12 is able to connect to networks, not just scan. What you're missing is that a bunch of the Wi-Fi firmware blobs were removed from the base system between FreeBSD 14.2 and 14.3, and since 14.3 came out in June 2025 I assume that's what was tested. An upgrade from 14.2 to 14.3 would also have kept working, just not a fresh install of 14.3 or 15.0.
A user needs some other working network connection first. I used my Android phone's USB tethering — all that takes is a quick `dhclient ue0`. Then one can run `fwget` to get the firmware that will make the Wi-Fi work fully: https://man.freebsd.org/cgi/man.cgi?fwget%288%29
Source: very happy Framework 12 owner (currently dual-booting Windows 11 Enterprise and FreeBSD 15.0 + Wayland + KDE) :)
I have tried this very same combination - F12 + FreeBSD + KDE on Wayland and WiFi works to me out of the box (even during installation!), but a lot of things doesn’t work for me - suspend and resume doesn’t work at all (even when I blacklist WiFi kernel module - suspend starts working, but resume doesn’t). A lot of apps on KDE also crash for me - every time I try to run Konqueror or Falkon they crash immediately).
