It’s a driver thing I guess, you need proper software to control the hardware properly, if the system has proper software built in, it will work properly, if it doesn’t have proper software built in, it will not work properly.
//EDIT this thread seem similar to your issue and his solution was kernel 5.11 Wifi misbehaving and this other thread has another solution RTL8822BE Wi-Fi not showing - #4 by Wollie. Try simple solution first, install kernel 5.11 and see. If it doesn’t work then try maybe the other one.
