WiFI SDIO Broadcom, Infineon 43455,  Notes to learn from for FreeBSD / GhostBSD-Arm64 https://wiki.gentoo.org/wiki/Raspberry_Pi4_64_Bit_Install#WiFi WiFi WiFi needs three firmware files from in /lib/firmware/brcm/ : brcmfmac43455-sdio.bin brcmfmac43455-sdio.clm_blob brcmfmac43455-sdio.txt Which is almost but not quite the same as the Pi3. The catch is in brcmfmac43455-sdio.txt where grep boardflags3 produces different results for the Pi3 and Pi4 files. The Pi4 version returns boardflags3=0x44200100 The Pi3 version returns boardflags3=0x48200100 With the wrong brcmfmac43455-sdio.txt file, bluetooth will work but not WiFi. These files, including the Pi 4 version of above file, are found in sys-firmware/raspberrypi-wifi-ucode , to install it you'll also need to install sys-kernel/linux-firmware with the savedconfig USE flag and remove the conflicting files from the saved configuration, and then re-emerge linux-firmware to apply the new de-conflicted saved configuration: /...
