Hello guys,

First of all I'm french so excuse me if my english isn't perfect
I'm new to Linux and I recently decided to install Nobara OS version 37 (a Fedora based distro). Everything was working well. There was only one thing: I installed the GNOME version while i actually wanted the KDE one so I just reinstalled the KDE version. After the installation I noticed that I had no wifi nor bluetooth: "no adapters found".
So I went back and reinstalled the GNOME version of Nobara OS: same problem.

Here are my computer specs:
Desktop running Nobara OS version 37 running kernel 6.2.12-200.fsync.fc37.x86_64
-AMD Ryzen 7800X3D
-ROG Strix B650E-F gaming wifi with the Mediatek MT7921K Network Adapter
-32Go of DDR5
-AMD RX6900XT

Useful commands outputs:

(from what I understood mt7921e is an alias for my card which is the mt7921k)

Here is everything that I tried:
-Install other Linux distributions namely Fedora and Pop_OS
-Removed and re-added the kernel module with the driver
-Resetted BIOS to default settings
-Checked wifi was enabled in BIOS

Does anyone have an idea of what's the problem? Any help would be appreciated!

Thanks!

Try installing the LTS kernel as mentioned here.

Bluetooth not working | mt7921e

It looks like your WiFi adapter not has an update for F38 yet. As a workaround you could try the LTS Kernel so you could at least use your system. kwizart/kernel-longterm-6.1 Copr

Ok I'm working on it, for the record I typed some of the commands that I've seen in the article you've mentioned in case it can help I'm pasting it there:
nmcli radio all WIFI-HW WIFI WWAN-HW WWAN missing enabled missing enabled
rfkill list all (outputs nothing)
 
try installing webmin, it is a web based management setup and if you install it you will have access to many things all in one place. this case you would go into the hardware and networking and see what it finds. You may just need to tell it to enable the adapter. This has happened to me before too.
 
I came across some posts about more people having problems with that driver, for some people the solution was resetting the BIOS, have you tried that? There seems to be a github issue on open on the openwrt project about that driver.
github.com

I would watch this issue and see what happens.
 
I have never been keen on mediatek products, they always seem to create some problem or another,
have you tried to re-boot the bios [whilst switched on, save all work, press and hold power button for 60 seconds, release and re-boot, no guarantees, but it often works

For some reason I can't install it! I tried adding the repo and installing it manually with the rpm but none of these methods worked as dnf outputs: Unable to identify operating system error: %prein(webmin-2.021-1.noarch) scriptlet failed, exit status 2
That surely must be because my distro is based on Fedora and not Fedora itself.

I reloaded the BIOS to its defaults twice already. Indeed the problems mentionned in this post seems to be the same issue as mine!

Yes I've seen a lot of problems related to mediatek chips. I've read on the Asus website that this solution was only for the laptops but I'm going to try then.

it does sound like the "fedora like" system has enough difference that webmin will not install. I attached the repo file which may help then you can use dnf install webmin and it may work. put it into the /etc/yum.repos.d folder.

just in case the attachment does not work...

[Webmin]
name=Webmin Distribution Neutral
#baseurl=http://download.webmin.com/download/yum
mirrorlist=http://download.webmin.com/download/yum/mirrorlist
enabled=1

call it webmin.repo

Still does not work :( Same error.
 
It is beginning to sound like your only option [for a while at least] is to use a USB Wi-Fi adaptor, do you have an old one kicking around you could use for a test run [or one you can borrow from a friend]

I'll try some more things that people tried in the GitHub issue posted by @f33dm3bits and then I'll borrow one from a friend I guess.
That is so frustrating as it worked 2 days ago :'(

Just another thought, have you tried fixing broken packages

Alright I'll try that, if that doesn't work I might actually replace the actual physical chipset of my motherboard with an Intel AX210 and cross fingers that the antenna and the motherboard will accept the swap. I'm very angry that Asus decided to put such a garbage chipset on a 300€ motherboard so I'll make sure to fix that.
