@andrea-p wpa_supplicant-1:2.11-2.fc40.aarch64 will only work if you do not have brcmfmac.feature_disable=0x82000 in your kernel parameters for kernel="/boot/vmlinuz-6.9.12-401.asahi.fc40.aarch64+16k" in GRUB2 menu.
You can find your GRUB settings with the following:
$ sudo grubby --default-kernel
/boot/vmlinuz-6.9.12-401.asahi.fc40.aarch64+16k
$ sudo grubby --info /boot/vmlinuz-6.9.12-401.asahi.fc40.aarch64+16k
index=0
kernel="/boot/vmlinuz-6.9.12-401.asahi.fc40.aarch64+16k"
args="ro rootflags=subvol=root rhgb quiet rootflags=subvol=root"
root="UUID=990d9cc0-4a80-45f1-ba19-72e86f580a57"
initrd="/boot/initramfs-6.9.12-401.asahi.fc40.aarch64+16k.img"
title="Fedora Linux Asahi Remix (6.9.12-401.asahi.fc40.aarch64+16k) 40 (KDE Plasma)"
id="f2fe3c44cc4640b8b7be44e46b5b7bfe-6.9.12-401.asahi.fc40.aarch64+16k"
In the args= line, if you added brcmfmac.feature_disable=0x82000, you can remove this setting with the following grubby command:
$ sudo grubby --remove-args="brcmfmac.feature_disable=0x82000" \
--update-kernel /boot/vmlinuz-6.9.12-401.asahi.fc40.aarch64+16k
The above assumes that you added the extra arg brcmfmac.*to the 6.9.12-401 kernel. Hope this helps!
