POCO F1 (beryllium) - 2.4GHz WiFi conection disconnects periodically

Describe your issue

What's the expected behaviour?

WiFi works without interruptions.

What's the current behaviour?

Something causes 2.4G wifi connection to disconnect in random periods of time which results in buggy ssh connection, unstable internet connection and other related issues. 5g wifi doesn't work at all (both on systemd and open-rc).

How to reproduce your issue?

Connect to 2.4GHx network and observe the WiFi indicator. You can see that it keeps disconnecting periodically at x seconds intervals. Try to type something over ssh and it will lag a lot if connects at all.
