I have had all the same issues mentioned previously.
Upgrading to the new version wpa_supplicant 2:2.11.2 and rebooting did NOT work for me and still has my WiFi not functioning.
Downgrading to wpa_supplicant-2:2.10-8 and rebooting is a temporary fix that worked for me until this can be solved long term. Iāve placed this package into /etc/pacman.conf for now.
Odd. This must be targeting very specific machines. Both my late 2014 MacMini and my 2021 Samsung Galaxy Book Pro laptop are fine after updating to wpa_supplicant 2:2.11.2.
I tried upgrading again on my x86 Dell XPS 15 9550 and the latest version of wpa_supplicant: 2.11-2 did not work again. Wanted to double check but this is still a bug for my laptop. Iāve reverted again to 2.10-8.
Thanks for the feedback.
Until wpa_supplicant adds the info for your particular WiFi chip it will still fail.
I am guessing it is still a long way off, if ever.
