Disabling PMF doesn't work anymore
I had trouble connecting to my 5Ghz WiFi in the past that I solved by disabling PMF using
nmcli connection modify <connection> wifi-sec.pmf disable
, that added pmf=1 in [wifi-security] section in connection conf (source: https://fedoramagazine.org/troubleshoot-pmf-f28/).
But since update to 1.14.6 from 1.14.5dev+17+gba83251b (Arch Linux) workaround doesn't work anymore and I see again error messages, mentioned in the article, that I saw before:
wpa_supplicant[611]: wlp2s0: WPA: Failed to configure IGTK to the driver
wpa_supplicant[611]: wlp2s0: RSN: Failed to configure IGTK
Downgrading fixed the problem.
