Posting this in case others encounter it. I have the setup noted below from inxi -F, with a Broadcom BCM43602 wireless card.
Upon upgrade (after a few months away) to the 6.1.31-2-MANJARO kernel, my wireless appeared to be working, but did not see any access points. I did some digging and found this error brcmf_cfg80211_add_iface: add iface p2p-dev-wlp3s0 type 10 failed: err=-12.
I installed the b43-firmware package, which uninstalled manjaro-firmware. On reboot, wireless worked as expected.
I am not sure if manjaro-firmware does not have the correct drivers for the Broadcom 43xx devices, but it did not work with my system and card.
