Description Michael Braunstein 2025-09-29 18:39:22 UTC
After install onto blank machine Networking works fine. Software then connects and downloads updates. After reboot the icon for wifi disappears from my Lenovo ThinkPad W53core i7 QC 3270qM 1344150159 skb-517291  and there is no wifi in settings and no icon in the top corner of the screen. A google search found some command line suggestions that did nothing.

Reproducible: Always

Steps to Reproduce:
1.Install Fedora 42
2. Run Updates
3. No WIFI networking
Actual Results:
No network settings anywhere

Expected Results:
Laptop continues working

Comment 1 Íñigo Huguet 2025-09-30 05:45:22 UTC
Please collect the kernel logs and attach them: journalctl -b -k > kernel.log

Same for NetworkManager logs: journalctl -b -u NetworkManager > nm.log

Also, tell us the outputs of these commands:
  ip addr
  iw dev
  nmcli d

dnf4 history entry for update that broke networking

Comment 5 Markus Himmel 2025-10-06 09:28:33 UTC
I have also lost wireless networking after the most recent update (via KDE Discover). I have attached network manager and kernel logs as well as the dnf4 history entry showing the packages that changed during the update which broke networking. In the network manager logs, it can be seen that the wireless device wlp4s0 is discovered before the update and does not appear after the update.

I am experiencing the problem on a Lenovo ThinkPad Z16 Gen 2.

Kernel log from machine with linux-firmware 20250917-2.fc42

It seems to be specifically linux-firmware 20250917-2.fc42. I initially suspected just mt7xxx firmware (that's my wifi), but there are other system issues as well (and they can't be upgraded individually via dnf).

Luckily, I use snapper and am able to recover to a previous system snapshot, and test updates individually. I suspect a lot of users will not be in a similar position, and may have issues recovering (this laptop, Thinkpad Z13, doesn't have a NIC. So it would be difficult to get a fixed update had I not had snapshots).

Aside from non-functioning wifi, the system also has an unusually high (>1) load average (top output included). Additionally, it hangs at "System Power Off", requiring holding the power button to shut down.

I still have the bad root with the affected firmware available if any other logs are required.

I've also added a note to bodhi for this update.

(Rest of the logs to follow, I believe I can only add one attachment at a time.).

`iw dev` had no output, thus no log attached.

Probably related: #2401216

Reassigning to linux-firmware as per comments above

Comment 16 William Oprandi 2025-10-07 10:34:42 UTC
I'm also impacted after update of linux-firmware & linux-firmware-whence packages :

Have you opened separate issues for these? I was also affected on a Thinkpad L13 Yoga Gen 4.

It may be related. Nothing else jumped out to me in the logs. Once #2401216 is resolved, if there is still a power/activity issue, I'll create a ticket.
