Wifi problems on Kubuntu (intel AX200 on a Gigabyte AERO 15 laptop)

[Anno Nymous]

Hi, I got a discussion on Kubuntu IRC forum, and I'm here to expose my situation with wifi.

First my wifi wasn't working at all (but bluetooth was), and after I disabled secure boot it worked.
I'm dual booting Kubuntu and Windows 11, and I disabled fast boot too.

But I got problems with the wifi connection : I got lag peaks from time to time, and the speed isn't good enough (compared to my phone for ex. : laptop got ~7Mbps, and phone 30Mbps).
Many people seems to have issues with this wifi card (even some windows users).

I saw some people on reddit that got lag peaks like me, but I don't know how to fix it.

I also got a personal 5Ghz router, but I got Internet from a 2.5Ghz router (that I don't own, it's the apartment router), and with my "custom setup", I got more speed, by connecting to the 5Ghz router, than with the 2.5Ghz one directly. I still got lag peaks though.

So here is my issue, I hope it will help you.
Have a great day.
