[Plasma 6] Wi-Fi and power buttons issues on plasma 6

[Aranycsapat]

Hello.
I'm facing a couple of problems with my gentoo. I'm a Plasma 6 user and once I close my laptop, all intenet (wifi) connections die immediately. Wifi remains dead after laptop openning. Only reboot restores it.
I have a 6.6.62 kernel built by genkernel.
I remember there was no such a problem on Plasma 5.
Moreover, sleep, restart and shut down buttons on the application dashboard don't work. There is no effect when I press them. Nothing happens. So, what should I do with that issues?
