Both Wifi and Bluetooth are not working in fresh install ubuntu 21.10

ph flag

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

Please edit your question to show the result of the terminal commands: `sudo modprobe iwlwifi` and also: `sudo dmesg | grep iwl`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
