Comment 28 for bug 1967690

Just some thoughts to further investigation.

Assuming the majority of german users use FB in "WPA2 + WPA3" mode at home, and control their wifi with NetworkManager, I wonder why this issue doesn't occur more often.

Except for the NM part, this also applies to you, Dirk, does it?

I experimented with a couple of settings today.

FB (7490 with current FW 7.29 and WPA3 transitional mode):

/etc/wpa_supplicant/wpa_supplicant.conf:

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
# enforce PMF
pmf=1|2
sae_pwe=0|2
#sae_groups=1 2 5 19 20 21 22 23 24
ieee80211w=1|2
key_mgmt=WPA-EAP WPA-EAP-SHA256|SAE

Variations are denoted by the pipe.

The initiated discover that this covers variations from optional WPA3 to mandatory MPA3-Personal. None of these setting variations result in a working configuration here.

I begin to believe, that older wifi hardware suffers from some unknown deficits, that contribute to this issue. Mine is a "Intel Centrino Advanced-N 6205 [Taylor Peak]" from my ten years old Lenovo X1 Carbon (Gen 1). Other, than that, I'm up-to-date: kernel 5.16.6 (a bit ahead of TW), kernel-firmware-iwlwifi-20220119, etc..
