So, I’m running 2.11-3 of wpa_supplicant. And still, not all networks appeared. Worse, my wireless coverage is poor. Perhaps I’m running off the CM4’s built-in antenna. (I checked. dtparam=ant2 is present in my config.txt) May I know what firmware you are using for the Wi-Fi, as well?
I haven’t had the best experience with iwd, historically. Maybe things will change in this kernel?
