I updated my Fedora KDE Plasma OS, and when I booted up immediately after the update, network connections were gone.
When I open the network menu in the bottom-right of my task bar, it states No available connections, even though there are tons, which all of my other devices are able to see and connect to.
I’ve seen that many other people seem to have a similar issue, and I tried their solutions but to no avail. I was hoping someone here could help me. Thanks!
I figured out the issue. For anyone who has the same problem, here’s the solution:
In the console, run:
sudo lspci -nnk | grep -i network -A4
Look for Kernel modules: and copy any names that are stated there.
Then run
sudo modprobe PUT_YOUR_KERNEL_MODULE_HERE
And you should see network working again shortly after.
That should have been automatic. I think you have noticed a bug.
Yep. It happened in a new small update to Fedora 42.
You could report the problem against the kernal in the fedora bug tracker.
See How to file a bug :: Fedora Docs
I think including the dmesg output before you load the module will be helpful.
FYI add kernel bug reports are read but few are replied to for lack of maintainer time.
Bugs with easy workarounds will be lower priority unless they affect large cubicle farms. Bugs that point to a specific change that causes the problem are more likely to get attention. Network bugs, however, often need vendor participation. Refurbished “enterprise class” systems are often still being used in large deployments so bugs do get attention.
i am facing the same issue.
i just deleted my windows 11 and installed fedora 42 kde plasma in my laptop.
i did the first step and for the second command i am getting command not found.
please help me from this issue.
Please start a new topic so we can help you.
From the few details you provide you have a different issue.
Hi,
I have this issue since upgrading to Fedora 43 from Fedora 42, after the upgrade my wired network stops working. (Works fine on live CD)
I’m brand new to linux, so i hope you can help a bit. When i run the first command “sudo lspci -nnk | grep -i network -A4” it runs in the terminal, but there is no output, where can i see the result from the command. Is there a file or something i have to check?
Thank you, BR Peter
I met the same problem when upgrading from kernel 6.17 to 6.18 in Fedora 42 : the kernel was updated but NOT kernel sources so the modprobe op fail as the network driver build cannot be done. I had to boot again 6.17 kernel to update kernel-dev repo.
This won’t print anything if the network interface isn’t detected.
Linux support is a community effort, and many issues are shared across multiple distributions, so you want it to be easy for others to find your topic with a web search.
You are more likely to get help if you start a new topic. You should provide enough detail (in a web-searchable text format) to allow others with similar hardware to reproduce the issue. A good way to do that is to install the inxi program and then run inxi -Fzxx in a terminal and post as pre-formatted text using the </> button from the top line of the text entry panel. You should also mention if the network interface has worked in the past or in the Live USB Installer. You can make it easier for others to reproduce your configuration if you have updated both Fedora and vendor firmware, and your issue may have already been solved with updates.
After having booted again the 6.17 kernel the Wi-Fi network worked fine again so i was able to run the “sudo dnf update kernel*” that updated kernel sources, modules and kernel-devel repo.
After reboot to 6.18 kernel networking was OK.
