I am also seeing this problem. My motherboard has an onboard Intel AX201
wireless module. 'lshw -class network' reports.
I am running ubuntu 24.04-1.

Clients associate but hang when the password is sent. Then timeout.
NO other information appears in the journals.
Other non intel devices work fine.This looks like as strange interaction
between NetworkManager and wpa_supplicant when an intel iwlwifi is being
used.
I have looked through network manager and wpa_supplicant source code for where
ap_scan=2 is set but have not found it. Has anyone tracked this down further?
