Arch Linux

Description: on my Lenovo T400 wifi connection only possible if routers wpa option set to wpa2 (CCMP).
The combination wpa2 + wpa3 does not work no more. No problrm on my other linux laptops.


Additional info:
core/wpa_supplicant 2:2.10-1
core/linux 5.16.5.arch1-1
(same with)
core/linux-lts 5.15.19-1

with wpa2 on router everything's fine and i get:
