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:

carlos@carlos:~$ sudo lshw -C network

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

  • Is this an issue? https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled Welcome to Ask Ubuntu. – chili555 Feb 25 '22 at 01:18
  • I've done it, still have the same problem – Carlospq17 Feb 25 '22 at 01:57
  • Please edit your question to show the result of the terminal commands: sudo modprobe iwlwifi and also: sudo dmesg | grep iwl – chili555 Feb 25 '22 at 03:13
  • Thank you very much, i've just solved my problem, i added a brief description of what turned out to be the problem and how i solved it. – Carlospq17 Feb 25 '22 at 03:29
