Chri01,
Your original post really doesn't give much to go on. "It doesn't work."
You say it works on a live Fedora image. Is this live instance the same version as you have installed? If so, the issue is with your installation.
First, check that NetworkManager is running
Code:
systemctl status NetworkManager
Ugh, yes, with systemd make sure you get the capitalization of NetworkManager right or you'll get an error.
Look for a line like
Code:
Loaded: loaded (/usr/lib/systemd/system/NetworkManager.service; enabled; preset>
Active: active (running) since Sun 2023-06-11 14:57:15 EDT; 3 days ago
Does it say "enabled" in the first line? Is it active? If not, as root
Code:
systemctl enable --now NetworkManager
systemd won't give you any confirmation. Check status again.
Error?
As root (or a user with journal permissions)
Code:
journalctl -xeu NetworkManager
That covers NetworkManager, and if the device is being detected and the module loaded, you may be lucky and this is your problem.
If not,
In a terminal
Does the interface (wlanX) show at all?

A similar card, though a different issue.
However, look at the dmesg output. Do you see anything like that, the backtrace when the driver module died? Look for lines following "
------------[ cut here ]------------" like in that thread, and see if anything under relates to the mt7921e module up to a follwoing "
---[ end trace ]---". Maybe that could give us some more info.
That error in probing could be a transient error. I get such errors from time to time with my Broadcom chip, and wifi works fine.
