Wifi drop regularly

aul16 · November 8, 2023, 5:57pm

Hello everyone,
I am new to Fedora and decided to use it full time on my LG gram laptop, but I have a wifi problem: it drops regularly (usually I just click on the wifi name directly and it reconnects, but never showed it was disconnected).

I am using this card :

00:14.3 Network controller: Intel Corporation Raptor Lake PCH CNVi WiFi (rev 01)

I got the log from journalctl but I wasn’t able to find out the reason.

Btw I had the same problem in Fedora 38 and I have already disabled wifi power management, that didn’t solve the issue.

I hope someone can help me

This is the important part from which we see that the chipset id for the wifi chip is
8086:51f1:8086:0094

It is using the iwlwifi driver as anticipated for intel chipsets but the issue is finding what causes it to drop regularly. You may check with that laptop and perform a probe at the linux hardware database to see what it may tell you. Sometimes minor changes in the chipset can affect performance.

Intel has historically done well in keeping the drivers up to date but occasionally there is a small lag between the hardware release and the release of the updated drivers. It often may need feedback in the form of filing a bug for issues with the newer hardware for the problems to become known.

Someone with more experience than I may be able to add to the troubleshooting suggestions.

Just as an additional note:
The log snippet you posted above is truncated at the right (ends with ‘>’) so we cannot see the full content of the messages. It is always a good idea to try and have everything included so the full details are available.

I also note that every disconnect & connect message is followed by an audit message with selinux attributes reported. This may be an issue with selinux interfering with wifi. We cannot tell exactly what the report is about since those lines are the ones that are truncated – though it clearly is related to network manager.
Maybe the simple act of running sudo restorecon -R / to reset all selinux context on the entire system may fix the problem. Restorecon may take some time to complete since it checks and verifies the context of every file on the entire system. The same may be done at boot time by using sudo touch /.autorelabel before shutting down then patiently waiting for the check and relabel to complete before the system will finish booting (restorecon does not interfere with normal operation of a running system in most cases).

Thank you for your answer. I’ll try to run the command. If the problem happen again, I will make sure to post the full log
