Can't use WPA3 security

English Network/Internet
1

My installation is Thumbleweed, KDE, NetworkManager with wpa_supplicant
It refused to connect if WPA3 is set.
My hardware is
02:00.0 Network controller: Intel Corporation Centrino Advanced-N 6200 (rev 35)
Subsystem: Intel Corporation Centrino Advanced-N 6200 2x2 AGN
Flags: bus master, fast devsel, latency 0, IRQ 29
Memory at f2400000 (64-bit, non-prefetchable) [size=8]
Capabilities: [c8] Power Management version 3
Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
Capabilities: [e0] Express Endpoint, MSI 00
Capabilities: [100] Advanced Error Reporting
Capabilities: [140] Device Serial Number 00-23-14-ff-ff-ab-f3-08
Kernel driver in use: iwlwifi

Other clients can connect with WPA3 in this WLAN

The Intel® Centrino® Advanced-N 6200 is from 2011 and very likely the hardware/driver does not support WPA3, WPA3 certification began only in June 2018.

I can connect with NetworkManager configured to use iwd backend and WPA3 on this hardware

I test wifi card with arhiso from USB-stick - it succesfully connects with SAE. So it seems that Tumbleweed wpa_supplicant built without SAE support?

Hi
AFAICS it’s enabled ‘-DCONFIG_SAE’

Hi! I check connection in Tumbleweed again, but without NetworkManager, only wpa_supplicant with -c config - it works!
~/install/iwd> sudo wpa_cli status
Selected interface ‘wlan0’

You are right, but NM therefore is something wrong

…then best to submit bug report.
