Wifi suddenly not working with router using WPA3

Issue is way complicated, because I have reinstalled OS not so long time ago, I have reverted miopen-hip package to older version, until fix for that will be released. Everything worked well until yesterday, I was connecting to wpa3 supported router and after about half hour simply lost internet connection, even can’t ping locally available server. But strange part, I am able access PC from macbook on same network. Reboot not helping, tried every configuration in networks section, even changing to wpa2. Connection always are created but no internet or access to local resources. Also updated kernel to 6.14, hopefully maybe that fixes that issue. After that I started to gather log records and not a lot is there happening. I can see this line when I am connecting to working wifi, but for wpa3 this is missing from log:

[1749652665.2022] manager: NetworkManager state is now CONNECTED_GLOBAL

And every time after connecting I got this one, for working networks I don’t see that.

systemd	NetworkManager-dispatcher.service: Deactivated successfully.

The last thing what I tried was installing dhcpcd and things got really interesting. For working wifi nothing changed, but now I am able to keep connection with wpa3, still till getting randomly message about previous mentioned dispacher deactivation after 5 minutes, but restarting dhcpcd restores connectivity after that.

Here are log from systemctl status NetworkManager

Then connection security - in this case wpa3 - has nothing to do with it.

It is more likely caused by using both IPv4 and IPv6.

In a SOHO (small office home office) scenario easiest solution is to disable IPv6.

//EDIT:

WPA3 is forcing PMF (Protected Management Frame) which may cause issues - if this is the case :man_shrugging:

From a quick search https://sx.nix.dk/search?q=AX200+and+WPA3 it appears that Intel AX200 may have issues with disconnects when using WPA3.

As I recall it, Intel is providing kernel drivers directly to the kernel source.
