This is my first time trying Linux
I first installed Ubuntu 20.04 and had the same problem where wifi and bluetooth icons wouldn't show in the bar menu, and wouldn't appear in settings menu.
I checked "Software & Updates" in case a driver were missing and it didn't showed, then i decided to install Ubuntu 21.10 in case that would help solve the problem and it keeps exactly the same.
I read this post and thought for a moment that this could be the error, and i just needed to wait for kernel 5.10, but then i did:
carlos@carlos:~$ uname -r
5.13.0-30-generic
And i have a higher version of that, so i don't know what could be the cause of this problem.
When i tried to check my bluetooth driver with:
carlos@carlos:~$ sudo dmesg | grep -i blue

Then, with my wifi i did:

I think it is also important to note that i also have Windows 10 installed on my SSD, in case that could cause some problems. And both wifi and bluetooth works perfectly fine there.
My Motherboard is a MSI z690-A Pro DDR4 Wifi.
EDIT: The problem has been solved, it turned out that the firmware version was newer than the kernel implementation.
I used mainline and select the lastest version and now i have both wifi and bluetooth working flawlessly
